Ever Wanted a Modern Mac Mini, but Windows? And for AI? The MS-S1 Max Review

The Minisforum MS-S1 Max is one of those mini workstations that looks straightforward on paper, but starts to feel unusual once you look at how it is put together and who it seems to be aimed at. It is built around AMD’s Ryzen AI Max+ 395, pairing a 16C/32T CPU with Radeon 8060S integrated graphics and an NPU that contributes to a quoted platform total of up to 126 TOPS. The big differentiator is the memory design: 128GB of LPDDR5x-8000 UMA, shared between the CPU and GPU, which changes the usual limits you hit on iGPU systems where VRAM is the first bottleneck. Minisforum also leans into “serious deployment” features here, including dual 10GbE, WiFi 7, USB4 v2, a slide-out chassis for maintenance, and even references to clustering and 2U rack mounting. The result is a machine that can make sense for creators, power users, and AI-focused workloads, but it also comes with a price level that forces the obvious question: what are you actually getting for that money beyond raw specs.

Minisforum MS-S1 Max Review – Quick Conclusion

The Minisforum MS-S1 Max is best understood as a compact Strix Halo workstation rather than a conventional mini PC, because its value is tied to the Ryzen AI Max+ 395 APU, the Radeon 8060S iGPU, and especially the 128GB LPDDR5x-8000 UMA memory pool that helps avoid the usual iGPU VRAM ceiling in creation, GPU-accelerated work, and local AI experimentation. It pairs that core platform with unusually strong external connectivity for its size, including dual 10GbE RJ45, WiFi 7, and a mix of USB4 and USB4 v2 ports that make high-bandwidth docks and storage setups practical, while the internal 320W PSU and heavy cooling stack are clearly built for sustained loads rather than short bursts. In testing, the system’s behavior has a few quirks that matter in daily use, particularly the way the chassis can feel hot to the touch in idle until the fan profile becomes more reactive under load, and the fact that noise ramps into the low 50 dBA range once the cooling really gets going, even if idle acoustics are more modest. Expandability is also a mixed bag: the slide-out design is convenient, but the storage layout includes a PCIe 4.0 x4 M.2 slot alongside a second M.2 limited to PCIe 4.0 x1, and the PCIe x16 slot is PCIe 4.0 x4 electrically, so it rewards buyers who already know what they plan to add. The price is the real gatekeeper here, because it only makes sense if you will actually use the UMA memory capacity, the iGPU performance, and the high-speed networking and USB bandwidth, but for that narrower audience, it offers a rare combination of compact form factor, strong APU compute, and connectivity that is difficult to match without moving to a much larger desktop or adding a discrete GPU.

Minisforum MS-S1 Max Review – Design & Storage

The MS-S1 Max feels like Minisforum took the general “mini workstation” idea and then built a thicker, more industrial version of it to cope with the Strix Halo platform. The chassis is metal and noticeably more substantial than the smaller MS-series boxes, with ventilation cut across multiple sides rather than relying on a single intake and exhaust path. It can be used vertically or horizontally thanks to feet on more than one face, which makes sense given how much of the marketing leans toward desk use one day and rack or shelf use the next.

Minisforum also keeps the slide-out structure here, and it is clearly intended to make maintenance less annoying than a traditional small desktop. In practice, it is still a compact, dense build, but you are not dismantling the entire enclosure just to access the main service areas. The system also has a couple of physical touches that make it feel more “deployment aware” than most mini PCs, like the mounting points underneath and the general emphasis on stacking, shelving, or grouping more than 1 unit together.

Storage is one of the areas where the MS-S1 Max shows both its strengths and its compromises. You get 2 internal M.2 2280 slots, but they are not equal: 1 is PCIe 4.0 x4 and the other is PCIe 4.0 x1. That means you can have a fast primary NVMe for OS and active work, but the second slot is better treated as capacity storage, warm data, or a secondary pool where peak throughput matters less. Minisforum ships the reviewed configuration with a 2TB Gen 4 SSD, so you can start testing immediately, but once you begin planning expansion, that lane split becomes a real consideration.

Physically, the M.2 placement is functional but not especially convenient. The slots sit low in the chassis near the base and tucked behind a lot of the cooling hardware, which makes upgrades feel more fiddly than they need to be. There is airflow down there, but it is not the kind of open, easy-access layout you get in a larger desktop. It also does not really encourage tall, pre-fitted heatsinks on SSDs, since clearance is limited and the space around the cooling assembly is tight. If you plan to run heavy sustained writes, you will probably end up choosing low-profile drives or slim heatsinks simply because it is the easiest fit.

On the expansion side, the MS-S1 Max includes a full-length PCIe x16 physical slot, but it is PCIe 4.0 x4 electrically, and that matters if you are buying cards based on the x16 shape alone. The form factor also pushes you toward half-height, half-length cards in most practical installs, and even then it can get cramped depending on cabling and where the PSU wiring runs.

In other words, the slot is useful for NICs, storage adapters, capture cards, and some compact accelerators, but it is not a “drop in any x16 card” situation, and the system rewards planning ahead before you buy hardware for it.

Minisforum MS-S1 Max Review – Internal Hardware

At the heart of the MS-S1 Max is AMD’s Ryzen AI Max+ 395, and the main thing to understand is that it is an APU platform built to behave more like a compact workstation than a typical integrated-graphics mini PC. You are getting a 16C/32T Zen 5 CPU with boost up to 5.1GHz, paired with an on-die Radeon 8060S GPU with 40 CUs and up to 2900MHz. In real use, that combination shifts the expectations around what “no discrete GPU” actually means, because the compute and graphics capability are designed to scale together rather than feeling like a strong CPU with an afterthought iGPU.

The most defining hardware choice is memory, because you do not get SODIMM slots here at all. The system uses up to 128GB LPDDR5x-8000 on a 256-bit bus, and it is shared between CPU and GPU via UMA. That has practical implications in workloads that normally hit VRAM limits first, like GPU-accelerated creative work or local AI inference, where the ability to allocate a much larger pool to the GPU can matter more than raw shader count. It also means your “upgrade path” is basically decided at purchase, so the value proposition depends heavily on whether 128GB UMA is something you will genuinely use, rather than just admire on a spec sheet.

On the AI side, the platform is marketed around a combined figure of up to 126 TOPS, with the NPU itself rated up to 50 TOPS. In day-to-day terms, that does not automatically translate into every app running faster, because it depends on whether your software actually targets the NPU, the GPU, or the CPU. What is clear from the positioning, and from how similar Strix Halo systems are being used, is that this design is meant to handle local model work without immediately forcing you into a discrete GPU purchase. That also explains why Minisforum leans into “run large models locally” messaging more than it usually does on its mainstream mini PCs.

Cooling and power delivery are tightly linked to the internal hardware decisions. Minisforum rates the system at 130W in Performance mode, 95W in Balanced, and 60W in Quiet, and the cooling stack is built around a copper base, 6 heat pipes, phase change material, and dual turbine fans, with a max fan speed of 3600 RPM. The PSU is internal and rated up to 320W, which helps explain why the chassis is thicker than many of Minisforum’s earlier workstations. In practice, that internal PSU choice also supports the idea that this box is expected to hold higher sustained loads than a typical mini PC without relying on a large external power brick.

There are also a few platform-level details that shape how “workstation-like” it feels. The system supports Windows 11 Pro and Windows 11 24H2 Pro/Home, and the BIOS is positioned as feature-rich, with fan monitoring and tuning options plus platform toggles that matter to power users. This is relevant because the MS-S1 Max is not just built for one narrow purpose, it is built for people who will switch between modes, tweak profiles, and repurpose it across different roles over time. If you treat it like a sealed appliance, you will still get high performance, but you are leaving a lot of what the platform is trying to offer on the table.

Minisforum MS-S1 Max Review – Ports & Connections

The MS-S1 Max is one of the more connectivity-heavy systems Minisforum has put out, and it is clearly designed around the assumption that it will sit in a workstation or lab environment rather than acting as a living-room mini PC. On the front, you get 2 USB4 ports at 40Gbps, a USB 3.2 Gen2 Type-A at 10Gbps, and a 3.5mm TRRS combo jack, plus 2 built-in DMIC mics that are pitched for voice and AI-assisted capture use. In practice, that front layout feels aimed at day-to-day convenience: fast external storage, a dock or capture device, and simple headset or mic options without needing to reach around the back.

On the rear, Minisforum doubles down on bandwidth. There are 2 USB4 v2 ports at 80Gbps, which is the kind of future-proofing that only really makes sense if you plan to use high-speed docks, external storage, or potentially GPU enclosures over time. The review experience lines up with that idea: the ports work as normal USB4 for most peripherals, but the value is really in the headroom, because 80Gbps devices and adapters are still not common in most studios. Alongside those, you get 2 USB 3.2 Gen2 ports at 10Gbps and 2 USB 2.0 ports, which is a more practical mix than it sounds, because it means you are not “wasting” high-speed ports on low-speed peripherals like keyboards, UPS management cables, or dongles.

Networking is a major selling point here, but it is also a slightly divisive one depending on your setup. The MS-S1 Max provides 2 10GbE RJ45 ports, both using Realtek RTL8127 controllers, and it also includes WiFi 7 and Bluetooth 5.4. In use, the wired ports are straightforward and do what you would expect in a compact workstation, including saturating 10GbE when paired with storage that can keep up.

WiFi 7 is also immediately usable, and the practical takeaway is that you can get multi-gig wireless performance without much effort if you already have a WiFi 7 router, but it is still not a replacement for wired 10GbE if you are treating this as part of a storage or production workflow.

Video output is handled through 1 HDMI 2.1 FRL port plus DisplayPort Alt Mode over USB4 and USB4 v2, which makes multi-display setups easy without any additional hardware. Minisforum rates these outputs up to 8K@60Hz and 4K@120Hz, and in the real world that means you can run high-refresh 4K displays or multiple monitors with less compromise than most iGPU-based mini PCs. The only real caveat is that the system leans heavily on USB4 for flexible display and peripheral expansion, so the people who get the most out of the port selection are the ones already planning to use docks, external storage, or high-bandwidth accessories, rather than just plugging in a keyboard and a single monitor.

Minisforum MS-S1 Max Review – Performance & Tests

In day-to-day use, the MS-S1 Max feels less like a typical mini PC and more like a compact workstation that happens to have an iGPU. General desktop operation is consistently responsive, and the platform’s bandwidth-heavy design shows up most clearly when you start stacking tasks that normally push integrated graphics systems into obvious slowdown. One thing that stood out early is how “hot to the touch” the exterior can feel when the system is sitting idle, with thermal imaging showing roughly 55 to 60°C around sections of the chassis and vents in that state. At the same time, internal sensor readings were not presenting anything alarming, which suggests the metal body is doing what it is meant to do as part of heat dissipation, but the idle fan curve behavior did not feel especially reactive until a workload actually kicked in.

Once the system is put under load, the cooling behavior becomes easier to understand and, in practice, more reassuring. During active workloads, the external readings dropped notably in many areas, with measurements around 31 to 34°C being observed on parts of the casing once sustained tasks were running, and internal hot spots that had looked extreme during idle did not remain in that range once the fan profile ramped. Noise levels followed the same pattern: at idle the system sat around 39 to 41 dBA, but under heavier load it ramped to roughly 51 to 53 dBA. It is not silent, but it is also not unexpectedly loud for a high-power APU system with multiple fans and a chassis that is clearly built to move air.

Power draw is one of the more interesting parts of the MS-S1 Max story because it is unusually low when the system is doing very little, then rises quickly once the GPU side is engaged. Idle consumption landed around 13 to 16 W, which is striking given the CPU, GPU, memory bandwidth, and overall positioning of the device. More moderate CPU-oriented workloads pushed consumption into roughly the 45 to 58 W range, with brief spikes into the 70 to 80 W area depending on thread behavior in the test. Once the Radeon 8060S was hit hard in GPU-heavy testing, total system power moved into triple digits, with figures around 141 to 158 W being recorded, which lines up with the idea that this chassis is designed to translate a lot of electrical budget into sustained APU performance rather than short bursts.

Benchmarking results were strong, but the platform’s newness made comparison data less useful than usual in several tools. PCMark produced a score of 8,353, and a run through 3DMark showed a wide spread depending on the test: Solar Bay scored 5,200, Speedway landed at 1,900 with frame rates around 18 to 19 FPS, and Steel Nomad Light cleared 11,000 with an average of 82.3 FPS. Night Raid, which is a better fit for integrated graphics platforms, came in at 70,000 overall, with a graphics score of 130,522 and a CPU score of 19,312. The practical takeaway from these results is that the MS-S1 Max can behave like a “real” gaming-capable APU system in the right workloads, but it also sits in a strange middle ground where some benchmark suites still struggle to place it cleanly against older mini PCs or discrete-GPU desktops.

Minisforum MS-S1 Max Review – Verdict & Conclusion

The MS-S1 Max is easier to understand once you stop thinking of it as a “mini PC with good specs” and instead treat it as a purpose-built Strix Halo workstation in a compact chassis. The big wins are the APU design and the 128GB UMA memory pool, because that combination changes what is practical on integrated graphics, especially for workloads that normally fall over due to VRAM limits. In use, it shows up as a system that can handle serious creative and compute tasks without immediately forcing you into a discrete GPU upgrade path, while still giving you enough connectivity to fit into faster workflows through dual 10GbE, WiFi 7, and USB4 v2. It is not flawless though: the system can feel surprisingly hot to the touch in idle despite internal sensors looking fine, and the fan behavior seems more tuned for “react under load” than “stay cool at rest,” which is a real-world usability detail you notice when it is sitting on a desk near you.

Where things get more complicated is the value discussion. At pricing around the mid/high $2,000 range depending on configuration, this is not competing with mainstream mini PCs at all, and it is not trying to. The audience is much narrower: people who want a high-bandwidth APU platform, who will actually use the memory capacity and fast external connectivity, and who are comfortable paying for that kind of compact engineering. If your workload is mostly general office, light creation, or basic homelab tasks, it is difficult to justify over more conventional systems, including Minisforum’s own smaller workstations. But if you are specifically chasing a compact workstation that can credibly do gaming, content work, and local AI experimentation without a discrete GPU, the MS-S1 Max is one of the few systems that makes that argument feel realistic, even if it comes with the usual early-platform quirks and a price tag that will still put off most buyers.

Did Minisforum FINALLY Go Too Far with the MS-02 Ultra?

The Minisforum MS-02 Ultra is positioned as a compact workstation that deliberately blurs the line between a high-end mini PC and a small server platform. While its physical footprint remains relatively small at 4.8 L, the design choices made across CPU selection, PCIe expansion, storage layout, and networking place it well beyond the scope of conventional desktop minis. During extended hands-on testing, it becomes clear that this system is not designed around a single use case. Instead, it targets users who expect to adapt the hardware over time, whether for professional content creation, software development, virtualization, NAS deployment, or mixed workloads that benefit from high I/O density. This flexibility comes with complexity, and the MS-02 Ultra expects a certain level of user familiarity with BIOS tuning, PCIe lane allocation, and thermal tradeoffs that are rarely encountered in this form factor. A key point that emerged during testing is how sharply the experience changes depending on which CPU configuration is selected. The Ultra 9 285HX variant is not simply faster than the lower-tier models. It fundamentally alters what the system can do by unlocking ECC memory support, enabling dual 25GbE SFP+ networking, and adding a PCIe combo card that expands total M.2 capacity to 4 slots. The Ultra 9 275HX and Ultra 5 235HX versions retain the same chassis and core platform, but they operate closer to a traditional high-end mini PC, with fewer storage options and reduced network throughput. As a result, the MS-02 Ultra range should be viewed less as a single product and more as a tiered platform, where hardware capability and intended role scale directly with price.

From a value perspective, pricing spans a wide range and reflects both component availability and Minisforum’s attempt to offer barebones and fully populated options. The entry barebones Ultra 9 285HX configuration sits at $1,199, while fully populated ECC-based builds can reach $2,999. During testing, it became apparent that much of the system’s long-term value is tied to its scalability rather than its out-of-the-box configuration. Users who intend to keep the system static may find better value in smaller Minisforum models, while those planning to expand storage, networking, or PCIe devices over time are more likely to benefit from the MS-02 Ultra’s architecture. This distinction frames the rest of the review, which focuses less on raw specifications and more on how those design choices behave in real-world use.

Minisforum MS-02 Ultra Review – Quick Conclusion

The Minisforum MS-02 Ultra is best understood as a compact but highly modular platform rather than a conventional mini PC, and its design clearly reflects that intent. It delivers strong CPU performance, extensive connectivity, and an uncommon level of internal expansion for a system of this size, but it also expects the user to engage actively with its configuration, cooling behavior, and upgrade planning. The system’s real strength lies in how well it can scale over time through additional storage, PCIe expansion, or higher-speed networking, rather than in any single out-of-the-box performance metric. Its pricing and hardware complexity place it firmly in enthusiast and professional territory, making it ill-suited for users who want a simple or inexpensive desktop replacement, but a compelling option for those seeking a compact system that can grow into demanding roles such as a workstation, NAS, or virtualization host as their needs evolve.

Minisforum MS-02 Ultra Review – Design & Storage

The MS-02 Ultra immediately distinguishes itself from earlier Minisforum workstation designs by abandoning the lighter, more modular internal layout used in systems like the MS-01 and MS-S1 Max. Instead, the chassis adopts a far denser internal structure that resembles a compressed micro-tower, with components stacked tightly around a central airflow channel. While the system still uses a slide-out internal frame, the motion is more deliberate and less fluid than previous designs due to the weight and density of the installed hardware. This approach prioritizes structural rigidity and thermal containment over ease of access, signaling that the MS-02 Ultra is designed to be configured carefully rather than frequently opened.

Storage implementation is one of the defining aspects of the MS-02 Ultra, particularly on the Ultra 9 285HX configuration. In this model, storage is split across the motherboard and a dedicated PCIe combo card. Two M.2 NVMe slots are mounted directly on the board and are positioned close to the CPU and memory area, which places them inside an active airflow path but also imposes strict height limitations. SSDs with tall, pre-attached heatsinks are not practical here, and Minisforum instead supplies low-profile heatsinks intended to work within the confined space. During testing, this design proved functional, though it requires more planning than a conventional desktop layout.

The additional two M.2 slots are integrated into the PCIe card that also houses the dual 25GbE controllers. This card is exclusive to the Ultra 9 285HX version and is responsible for expanding total NVMe capacity from 2 drives to 4. Unlike typical expansion cards, this unit combines networking and storage on a single PCB and includes its own active cooling solution. In use, the card introduces noticeable power draw even when the network interfaces are idle, but it also centralizes high-speed I/O in a way that simplifies cabling and internal layout. This design choice is unusual, but it aligns with the system’s goal of maximizing capability within a small enclosure.

There are also important performance considerations tied to how storage bandwidth is allocated. The motherboard-mounted M.2 slots are specified as PCIe 4.0 x4, but during testing, lane sharing and PCIe crossover behavior resulted in scenarios where one slot operated at PCIe 5.0 x4 while others were reduced to PCIe 3.0 x4. This was not immediately obvious from the documentation and required closer inspection of the PCIe lane map and BIOS configuration to fully understand. While overall throughput remained strong across all drives, the behavior highlights that the MS-02 Ultra expects users to pay attention to lane allocation if they intend to fully populate all storage bays.

From a practical standpoint, the storage design reflects the broader philosophy of the MS-02 Ultra. It offers unusually high capacity and flexibility for a system of this size, but it does so by imposing constraints related to drive selection, thermal clearance, and PCIe bandwidth sharing. For users planning a fixed configuration, these limitations are manageable once understood. For those intending to experiment with different storage combinations over time, the layout rewards careful planning rather than casual swapping. This reinforces the idea that the MS-02 Ultra is engineered for deliberate, long-term deployment rather than frequent hardware iteration.

Minisforum MS-02 Ultra Review – Internal Hardware

At the core of the MS-02 Ultra is Intel’s Core Ultra HX platform, with the Ultra 9 285HX representing the most complete implementation of what this chassis can support. This processor combines 8 P-cores and 16 E-cores, allowing the system to scale from low-load background tasks to sustained multi-threaded workloads without the immediate thermal collapse often seen in compact systems. In practice, the CPU feels closer to a desktop-class part than a mobile processor, particularly when sustained power limits are raised in the BIOS. That capability comes with tradeoffs in power draw and cooling demand, but it also defines the MS-02 Ultra’s positioning as something far more ambitious than a conventional mini PC.

Memory support further reinforces that distinction. The system includes 4 DDR5 SODIMM slots, but only the Ultra 9 285HX variant enables ECC functionality. During testing, ECC was supported at 4800 MT/s, and while that frequency is lower than some non-ECC DDR5 kits, the stability benefits are clearly aligned with the system’s server-adjacent ambitions. The physical layout of the memory slots is unconventional, with 2 slots positioned close to the CPU cooling path and the remaining 2 mounted on the opposite side of the board.

Minisforum has added a custom heatsink over part of the memory and nearby controllers, suggesting thermal behaviour around the DIMMs was significant enough during development to warrant dedicated mitigation.

PCIe lane availability is one of the most critical aspects of the MS-02 Ultra’s internal design. The system exposes 3 PCIe slots: 1 PCIe 5.0 x16 slot, 1 PCIe 4.0 x16 slot, and 1 PCIe 4.0 x4 slot. Notably, the PCIe 5.0 x16 slot is not occupied by the bundled 25GbE combo card, leaving it available for future expansion. This is an unusual design choice in a system of this size and points to forward-looking intent rather than immediate necessity. However, physical space limits the practicality of using this slot to low-profile, short-length cards, which significantly narrows the pool of compatible GPUs and accelerators.

Power delivery inside the chassis is handled by an internal 350 W PSU, which is uncommon for systems in this size class. During teardown and testing, it became clear that Minisforum opted for an internal unit to support higher transient loads and to provide direct power connectors for PCIe devices. While an external PSU would have simplified thermals and internal space management, the internal design enables a cleaner external setup and removes a common bottleneck seen in expandable mini PCs. The tradeoff is increased internal heat density, which places more responsibility on the cooling system to manage both CPU and power delivery components simultaneously.

Overall, the internal hardware configuration of the MS-02 Ultra reflects a deliberate shift away from simplicity and toward flexibility and scalability. Each major subsystem, CPU, memory, PCIe, and power delivery, is implemented in a way that assumes the user will actively engage with BIOS settings, lane allocation, and hardware planning.

This makes the system less forgiving for casual users but far more capable for those who intend to push it beyond default configurations. Rather than hiding complexity, the MS-02 Ultra exposes it, which is both its defining strength and a potential barrier depending on the user’s expectations.

Minisforum MS-02 Ultra Review – Ports and Connections

The MS-02 Ultra offers a port layout that reflects its hybrid workstation and infrastructure-focused design rather than a consumer desktop orientation. On the front panel, Minisforum has placed 2 USB4 v2 Type-C ports operating at up to 80 Gbps, alongside a single USB 10 Gbps Type-A port, a 3.5 mm audio jack, and the power button. In practical use, the front USB4 v2 ports proved capable of sustained high-throughput operation, including external NVMe enclosures where transfer speeds in the 6 to 7 GB/s range were observed. This makes the front panel suitable not just for peripherals, but for temporary high-speed storage, capture devices, or docking solutions without needing to access the rear of the system.

The rear I/O panel expands connectivity significantly and is where the system’s infrastructure focus becomes clearer. It includes 1 USB4 Type-C port at 40 Gbps, 3 USB-A ports at 10 Gbps, and a full-size HDMI 2.1 port supporting high-resolution and high-refresh output. The HDMI port provides a straightforward display option for setups that do not rely on DisplayPort over USB4, which is useful in environments where compatibility or cable length is a concern. Together, these ports support multi-display configurations without requiring a discrete GPU, though display bandwidth sharing across USB4 ports should still be considered when attaching multiple high-resolution monitors.

Networking is one of the defining characteristics of the MS-02 Ultra, particularly on the Ultra 9 285HX model. This version includes the previously mentioned 2 25GbE SFP+ ports delivered via the internal PCIe combo card, in addition to a 10GbE RJ45 port and a 2.5GbE RJ45 port. Each wired interface uses a separate controller, allowing simultaneous multi-tier networking without shared bandwidth bottlenecks.

In testing, the presence of multiple active network controllers contributed to higher idle power draw, but it also enables complex routing, storage, or virtualization scenarios that would normally require a much larger system. The 2.5GbE interface also supports Intel vPro, allowing remote management and BIOS-level access in supported environments.

Wireless connectivity is handled by an onboard WiFi 7 and Bluetooth 5.4 module, with external antenna connectors located at the rear. In close-range testing, WiFi 7 throughput exceeded 5 Gbps when paired with a compatible router, making it a viable option for high-speed wireless workflows when cabling is impractical.

While wireless connectivity is unlikely to replace the wired interfaces for sustained workloads, its inclusion rounds out the system’s connectivity and reinforces the idea that the MS-02 Ultra is designed to function in a wide range of deployment scenarios, from desk-based workstations to lab or rack-adjacent environments.

Minisforum MS-02 Ultra Review – Speed, Noise, Heat and Power Tests

In day-to-day operation, the MS-02 Ultra behaves closer to a compact desktop workstation than a typical mini PC, particularly when configured with the Core Ultra 9 285HX. General responsiveness under Windows 11 Pro was consistently strong, even with multiple background tasks running, and the system showed no signs of instability during extended uptime.

Light workloads such as desktop productivity, media playback, and development tools rarely pushed power draw beyond moderate levels, although the presence of the 25GbE combo card does raise baseline consumption compared to smaller Minisforum systems.

CPU-focused testing highlighted the platform’s ability to sustain high loads, but also underscored how aggressively the system can scale power. In Cinebench, single-core workloads typically drew around 65 to 70 W, while full multi-core runs pushed total system power beyond 200 W at peak. These figures are unusually high for a system of this size, but they align with what would be expected from a high-core-count HX processor running with elevated power limits. Despite this, the cooling system maintained control, with external chassis temperatures remaining within reasonable limits even during prolonged stress periods.

Integrated graphics performance was evaluated using a mix of synthetic benchmarks and real-world gaming tests. Cinebench GPU and PCMark scores placed the system solidly ahead of most integrated-graphics mini PCs, but well below even mid-range discrete GPUs. In practice, games such as Sons of the Forest and Street Fighter 6 were playable at 60 FPS using medium settings, confirming that casual and light gaming is viable without additional hardware.

However, more demanding benchmarks like Steel Nomad and Solar Bay Extreme demonstrated clear limitations, reinforcing that users seeking higher graphical fidelity or advanced rendering will need a discrete GPU or external GPU solution.

Where the MS-02 Ultra differentiates itself is in scalability rather than raw out-of-the-box performance. USB4 ports supported external GPUs and high-speed storage without issue, and internal PCIe expansion allowed for measurable gains when discrete graphics were introduced. Storage benchmarks showed expected scaling across PCIe generations, with PCIe 5.0 NVMe drives exceeding 12 GB/s, PCIe 4.0 drives reaching around 6 GB/s, and PCIe 3.0 drives performing in line with their specifications. Overall, performance testing confirmed that the system’s architecture prioritizes flexibility and sustained throughput over specialization in any single workload.

Disclaimer on 25GbE and NAS Testing

This review does not include full performance validation of the dual 25GbE SFP+ interfaces or in-depth NAS and virtualization benchmarking. At the time of testing, a complete 25GbE network environment was not yet in place, which prevented meaningful throughput, latency, and sustained load testing of those ports. As a result, the networking discussion in this article is limited to hardware behavior, configuration, and early observations rather than verified performance metrics. A dedicated follow-up video and article are planned that will focus specifically on deploying the MS-02 Ultra as a NAS and Proxmox host, including detailed 25GbE testing, storage performance under RAID and VM workloads, and long-term stability analysis.

Minisforum MS-02 Ultra Review – Conclusion & Verdict

After extended testing, the Minisforum MS-02 Ultra stands out as one of the most ambitious small-form-factor systems Minisforum has produced to date. It is not designed to be a simple plug-and-play mini PC, and it does not try to hide that fact. Almost every aspect of the system, from PCIe lane allocation to storage layout and cooling behavior, assumes the user will be willing to spend time understanding how the hardware fits together. In return, it offers a level of flexibility that is uncommon at this size, combining workstation-class CPU performance with expansion options that normally require a much larger chassis. The result is a system that feels closer to a modular platform than a fixed appliance.

In practical use, the MS-02 Ultra proves capable across a wide range of workloads, but its real value lies in how well it scales beyond its default configuration. CPU performance is strong enough for sustained professional tasks, integrated graphics are sufficient for light gaming and creative work, and the internal and external expansion options open the door to far more demanding roles over time. At the same time, the pricing, particularly for ECC-equipped or fully populated configurations, places it firmly in enthusiast and professional territory. Users who want something quiet, simple, and inexpensive will likely be better served by smaller Minisforum systems. For those who are comfortable tinkering, planning future upgrades, and investing in a platform that can evolve alongside their needs, the MS-02 Ultra delivers a rare combination of compact size, connectivity, and long-term adaptability that few systems currently match.

PROs of the Minisforum MS-02 Ultra	CONs of the Minisforum MS-02 Ultra
Strong multi-core CPU performance that approaches compact desktop-class systems Unusually high internal expandability for a 4.8 L chassis PCIe 5.0 x16 slot available for future expansion Dual 25GbE SFP+ networking on the 285HX model Support for ECC DDR5 memory on the 285HX configuration Four M.2 NVMe slots available on the top-tier model Internal 350 W PSU with auxiliary power for PCIe devices USB4 v2 ports capable of very high external storage and docking throughput Suitable for multiple roles including workstation, NAS, and virtualization host	High pricing for a area of the market where buyers are getting used to low, low prices, even for ECC-equipped or fully populated configurations Limited physical space restricts larger GPU and PCIe card choices Fan control largely confined to BIOS with limited OS-level adjustment (TBC) Complexity and tuning requirements may deter less experienced users who want to maximize their investment in this system
