Minisforum MS-A2 Review – Internal Hardware

Inside the Minisforum MS-A2, users have a choice between two processors: the AMD Ryzen 9 9955HX or the Ryzen 9 7945HX. Both CPUs offer 16 cores and 32 threads, with a maximum boost clock of 5.4GHz. The 9955HX uses the newer Zen 5 architecture, while the 7945HX is built on Zen 4. The two processors are close in raw specifications, but the Zen 5 variant benefits from a more efficient 4nm process and updated IPC improvements. Integrated graphics are handled by the Radeon 610M on both options, offering basic graphical capabilities suitable for general-purpose workloads, but not designed for high-end gaming or intensive GPU compute tasks.

Memory support on the MS-A2 is generous for a mini PC. It features two DDR5 SO-DIMM slots, allowing up to 96GB of RAM. Systems based on the Ryzen 9000 series CPUs support memory speeds up to 5600MT/s, while Ryzen 7000 series CPUs are rated for up to 5200MT/s. This flexibility gives users room to configure the system for heavy multitasking, virtualization, or memory-hungry professional applications. However, the MS-A2 does not support ECC memory, which may be a consideration for users needing strict data integrity for server or professional workstation tasks.

Storage options are extensive, with three onboard M.2 slots available. One slot supports U.2 or standard M.2 NVMe drives up to 15TB (PCIe 4.0 x4), while two additional M.2 slots support either NVMe or SATA drives up to 4TB each.

All slots run at PCIe 4.0 speeds, ensuring strong storage performance for workflows like video editing, virtual machines, or database management. Minisforum also hints at future expandability through an optional accessory that would allow for the installation of up to six M.2 drives, although cooling for such configurations is still under development.

Cooling inside the MS-A2 is designed to accommodate the considerable thermal output of the CPUs and storage devices.

A dedicated CPU cooling system with copper piping and a 12V fan handles the processor, while a second 5V fan directly cools the SSD slots and the 10GbE controller. Despite the compact space, Minisforum has optimized airflow reasonably well, but heat sink space is limited, especially for M.2 drives, making active airflow critical.

Overall, the internal hardware layout focuses on balancing high performance with maintainability, though users planning extensive upgrades should be aware of space and thermal limits.

Minisforum MS-A2 Review – Ports and Connections

The Minisforum MS-A2 is equipped with a wide range of external connectivity options aimed at both workstation and server-style deployments. On the front panel, users will find two USB 3.2 Gen 1 Type-A ports, one USB 2.0 Type-A port, a 3.5mm four-in-one audio jack, and the system’s main power button with integrated LED indicator. This arrangement makes it easy to quickly connect peripherals like external drives, keyboards, or headsets without reaching around to the back of the device.

The rear panel is where the MS-A2’s workstation orientation becomes more evident. It features two USB 3.2 Gen 2 Type-A ports, two USB 3.2 Gen 2 Type-C ports with Alt Mode DisplayPort 2.0 support, a single HDMI 2.1 output capable of 8K60 video, and dual 2.5GbE RJ45 ports powered by Intel controllers. More notably, the system also includes two 10GbE SFP+ ports driven by an Intel X710 controller, opening up high-speed networking options typically reserved for larger systems.

This broad mix of ports covers a wide range of use cases, from high-resolution displays to enterprise-grade network environments.

The MS-A2 also provides PCIe expansion via a PCIe Gen 4 x8 physical slot, allowing users to install low-profile cards such as additional NICs, storage controllers, or even mobile GPUs through adapters. While the slot runs at x8 electrically, it can mechanically accommodate a x16-sized card, offering some flexibility in component choice.

However, users will need to consider power and thermal requirements carefully, given the limited space and airflow in the chassis. Overall, the MS-A2 offers a strong set of external connection options that match its intended role as a workstation-class device in a small form factor.

Minisforum MS-A2 Review – Design, Cooling and Power Consumption

The Minisforum MS-A2 maintains a compact footprint at 196 × 189 × 48 mm, but compared to typical mini PCs, it leans toward a small form factor workstation design rather than an ultra-portable device. Accessing the internals is straightforward thanks to a tool-less design: a single latch at the rear releases the chassis cover, making upgrades and maintenance simple. Ventilation is placed around all sides and across the base, maximizing airflow within the tight internal layout. Although densely packed, the internal component arrangement is relatively clean and accessible given the system’s size constraints.

Cooling inside the MS-A2 is split between two fans: a 12V fan for the CPU, which uses a heat pipe and fin arrangement, and a separate 5V fan cooling the storage area and 10GbE networking controller.

Minisforum has improved fan placement over the earlier MS-01 model, aiming to deliver better cooling to both the processor and critical components without introducing excessive noise.

During testing, the CPU temperatures at idle remained around 31–32°C, rising to approximately 50–52°C under sustained heavy load, including simultaneous 10GbE network activity and storage operations. SSD temperatures were also well-controlled, aided by direct airflow across the M.2 slots.

Power delivery for the MS-A2 comes through an external 240W power brick, rather than an internal PSU.

This design choice saves internal space but results in a relatively bulky external adapter. In idle conditions, the system drew between 23W and 26W, depending on network activity.

During maximum CPU load under PCMark and 3DMark testing, power consumption peaked at 129W.

Average system operation under moderate workloads saw consumption range between 60W and 80W. These figures suggest a reasonably efficient platform considering the CPU core count and networking capabilities, though users expecting true low-power behavior typical of smaller mini PCs should adjust their expectations accordingly.

Noise levels from the MS-A2 stayed moderate during most activities. Fan noise measured around 36–38 dB under light loads and rose to about 41–43 dB under heavy CPU and network utilization. This places the MS-A2 in a middle ground: quieter than larger workstations but more audible than simpler fanless mini PCs.

Overall, Minisforum’s cooling approach is effective for a compact workstation, balancing thermal performance and acoustic levels without the need for more aggressive—and louder—cooling solutions.

Metric	Measurement
Idle Power Consumption	23W to 26W (single 2.5GbE connection)
Boot-Up Power Consumption	35W to 75W (fluctuating during initial 5 minutes)

These results reaffirm that while the MS-A2 is well-suited to workstation and productivity tasks, it is not designed for gaming or heavy graphical processing without an external GPU.

CPU-centric benchmarks demonstrated the strength of the Ryzen 9 9955HX. In the 3DMark CPU Profile test, the MS-A2 achieved 10,208 points at maximum threads and 9,879 at 16 threads, with a respectable 1,235 points in single-thread performance.

These scores reflect excellent multi-threaded processing capabilities, making the MS-A2 a solid choice for parallelized workloads such as software compilation, virtualization, and data analysis. Across extended testing sessions, thermal throttling was minimal, and the system maintained consistent performance without significant drops under sustained load.

Storage performance varied depending on the drive slot used, but generally provided strong results. Read speeds were consistently high, reaching 5.5 GB/s in AJA testing and peaking at 7.3 GB/s in CrystalDiskMark. However, write speeds showed more inconsistency across different test runs, sometimes peaking near 4 GB/s but with occasional dips depending on the benchmarking tool and conditions. While read performance makes the MS-A2 well suited for workloads involving frequent large file access, users planning heavy write-intensive tasks may want to further validate storage behavior based on their specific needs.

Minisforum MS-A2 or the Minisforum MS-01 PC?

While the Minisforum MS-A2 and MS-01 share a compact workstation focus, they are built around notably different platforms and priorities. The MS-01 uses Intel’s 12th and 13th Gen Core H-series processors, with options ranging from the Core i5-12600H to the Core i9-13900H, alongside Intel Iris Xe integrated graphics. It supports up to 64GB of DDR5 memory at 5200MHz and offers storage flexibility with up to three M.2 SSD slots. Crucially, the MS-01 features two USB4 ports capable of 40Gbps speeds and supports external GPU connectivity, along with dual 2.5GbE RJ45 ports and dual 10GbE SFP+ ports for network-heavy environments.

In contrast, the MS-A2 leverages AMD’s Ryzen 9 9955HX or 7945HX CPUs, offering more cores (16 cores and 32 threads) compared to the MS-01’s maximum of 14 cores and 20 threads. It also supports up to 96GB of DDR5 memory and includes three PCIe 4.0 NVMe slots, but lacks USB4 or Thunderbolt connectivity. Instead, the MS-A2 leans on internal expandability with a full PCIe 4.0 x8 slot and places a stronger emphasis on internal compute performance rather than external device bandwidth. Users needing the fastest possible external drive support or lighter CPU performance may prefer the MS-01, while those requiring maximum multi-threaded processing power and internal storage scalability will find the MS-A2 better suited to their needs.
