The UniFi UPS-Tower 600W UPS Review

UPDATE – The Desktop UPS TOWER is available HERE for $159 , and the 2U Rackmount UPS-2U is available later in Q4 2025 HERE for $279

UniFi’s entry into the uninterruptible power supply market brings two distinct solutions tailored for professional and prosumer environments: the UPS-Tower desktop model and the UPS-2U Rackmount unit. The tower configuration provides 1,000VA / 600W of backup capacity and uses a single 12V, 9Ah lead-acid battery, while the larger 2U rackmount version scales up to 1,440VA / 1,000W with dual battery modules. Both adopt a line-interactive architecture with simulated sine wave output, a 6–10 ms transfer time, and Ethernet-based network management. Integration is handled natively within UniFi Network, where users can adopt, monitor, and configure the UPS directly from the UniFi Controller interface. For non-UniFi deployments, both models retain NUT (Network UPS Tools) compatibility for safe shutdown and system monitoring. This marks a significant expansion of UniFi’s ecosystem into power management and continuity—areas traditionally dominated by brands like APC and CyberPower—positioning UniFi’s UPS line as a bridge between smart network infrastructure and automated power protection.

The UniFi UPS-Tower 1000VA / 600W Review – Quick Conclusion

The UniFi UPS-Tower and UPS-2U deliver practical and ecosystem-focused power protection for small network environments. Both models emphasize integration and manageability rather than raw performance, providing stable 120V line-interactive backup power with simulated sine wave output. The tower model offers 600W of protection in a compact desktop enclosure, while the rackmount unit increases capacity to 1,000W with dual batteries. Integration through the UniFi Network Controller is straightforward, enabling central monitoring and alerting without external software. While limitations such as the lack of USB ports, PoE passthrough, and pure sine wave output restrict versatility outside the UniFi ecosystem, both units are solid entries for users seeking consistent, centrally managed backup power within UniFi-managed infrastructures.

The UniFi UPS-Tower UPS Review – Design & Connectivity

The UniFi UPS-Tower adopts a vertically oriented, compact chassis that measures 288 x 99 x 280.5 mm and weighs just over 8 kg. Its enclosure is built from a polycarbonate and ABS blend, which offers a balance between durability and low weight, and the overall shape resembles a small desktop speaker or heater.

The unit’s IP20 rating indicates it is intended for indoor use only, with ventilation panels positioned at the top, sides, and bottom to maintain airflow. During testing, internal temperatures averaged around 45–47°C after 24 hours of continuous operation, demonstrating stable thermal management for a unit of this density. The design is understated, with no LCD screen or physical display, relying instead on LED indicators and the UniFi interface for monitoring battery level and status.

In terms of connectivity, UniFi has implemented a clear division between power protection and control interfaces. On the rear panel, the UPS-Tower provides five surge-only outlets and five battery-backed surge-protected outlets, all of which are NEMA 5-15R ports suitable for 120V environments. The input connection uses a NEMA 5-15P plug, rated for 12A maximum load, supporting both 50 and 60 Hz operation. While this configuration is typical of compact line-interactive UPS units, the number of protected outlets is unusually high for its size, making it suitable for powering multiple small network devices, NAS units, or edge appliances simultaneously. However, only the five battery-backed ports will remain operational during a power loss.

UniFi has also included Ethernet management for remote monitoring and control. The rear I/O layout features a 100/10 MbE network connection that links the UPS directly into the UniFi ecosystem, as well as two GbE ports for surge in/out, allowing for protection of wired data paths. This implementation enables the UPS to send automatic notifications and power-state updates to the UniFi controller, ensuring that connected devices can safely power down when mains supply is interrupted. While users will not find USB connectivity here—a feature absent from both models—Ethernet management ensures seamless network-level integration with UniFi OS devices and provides remote monitoring capabilities not typically available in basic desktop UPS designs.

On the visual and operational interface side, UniFi relies on a multi-stage LED system to communicate battery and status information. A ring of LEDs on the front panel indicates power state, network connectivity, and battery percentage, with specific color patterns representing states such as initialization, adoption, or firmware upgrades. For example, a steady blue LED denotes normal operation, while flashing red signals a low battery, and alternating white/blue indicates firmware updating. This LED-centric approach aligns with UniFi’s existing product language and keeps the design minimalistic while relying on software integration for detailed telemetry.

Physically, the UPS-Tower fits neatly into a small office or studio environment, blending alongside UniFi routers or switches without dominating desk space. It operates quietly, with only a faint hum from the internal fan during battery mode. The 2U rackmount model, by contrast, uses a galvanized steel enclosure with front ventilation and nearly double the weight at 14 kg, prioritizing durability for data racks and wiring cabinets.

Both maintain an IP20 protection rating, ensuring basic safety against accidental contact but not dust or moisture resistance. Overall, UniFi’s approach emphasizes modularity, network integration, and compactness over display-driven functionality, positioning these UPS units as discreet but essential components within managed network setups.

The UniFi UPS-Tower UPS Review – Internal Hardware

Internally, the UniFi UPS-Tower follows a line-interactive architecture, combining voltage regulation with battery backup to ensure smooth transitions during power interruptions. The system utilizes an automatic voltage regulation (AVR) circuit that adjusts minor fluctuations in mains voltage without switching to battery mode, minimizing wear on the internal power cells. In the event of an outage or severe voltage dip, the UPS switches to battery operation within 6 to 10 milliseconds, maintaining output stability at 120V AC with a ±10% regulation margin. The waveform produced in battery mode is a simulated sine wave, which is adequate for most networking gear and consumer electronics, though not ideal for high-sensitivity audio, medical, or laboratory equipment. Power delivery remains consistent throughout short outages, allowing network hardware, NAS units, and servers to complete safe shutdown procedures.

The UPS-Tower contains a single 12V, 9Ah sealed lead-acid battery, user-removable via a bottom access panel. This design makes future maintenance straightforward, allowing owners to replace the battery when its capacity diminishes after several years of use. At full load (600W), the runtime averages around 2 minutes, while at half load, it extends to approximately 7 minutes before automatic shutdown. Recharge time to 90% capacity is listed at 6 to 8 hours. Thermal performance under sustained use is stable, and the inclusion of passive and active ventilation ensures no overheating under normal operating conditions. The system is also protected against short circuits, overloads, and over-voltage faults, automatically tripping into fault mode if thresholds of 110% to 120% load are exceeded.

Comparatively, the UPS-2U Rackmount uses a dual-battery setup with two 12V, 9Ah lead-acid modules to achieve 1,440VA / 1,000W output capacity. It shares the same waveform and transfer time but provides slightly extended runtime—2.3 minutes at full load and 8 minutes at half load—thanks to the added battery reserve. It also benefits from a galvanized steel chassis that enhances durability and is better suited for professional rack environments. Both systems are NDAA-compliant and certified under FCC, IC, UL 1778, and CSA C22.2 No. 107.3, ensuring safety and performance standards for commercial and residential use. In both models, system management and network telemetry are handled by a dedicated network controller chip, enabling UniFi OS integration and data synchronization with other UniFi devices.

The UniFi UPS-Tower UPS Review – Functionality

The UniFi UPS series is built around simplicity and ecosystem-level integration rather than feature-heavy configuration. Both the UPS-Tower and UPS-2U connect directly to the UniFi Network controller via Ethernet, where they appear alongside other UniFi devices for adoption. Once added, users can view real-time battery percentage, load level, input/output voltage, and system temperature directly from the UniFi interface. The units are also capable of sending power event notifications when mains power fails or returns, ensuring administrators receive alerts through the existing UniFi management system without relying on third-party monitoring software. This network-level approach allows the UPS to act as both a power backup and an automated coordination point for controlled shutdowns across UniFi infrastructure, such as Dream Machines, switches, or NAS units.

Integration with non-UniFi devices is handled through Network UPS Tools (NUT) compatibility. This makes the UPS-Tower particularly flexible in mixed environments where NAS devices or servers from other vendors, such as Synology or QNAP, require graceful shutdown when the UPS switches to battery mode. Users can define credentials and associate the UPS with NUT clients on the same network to relay status and trigger automated shutdowns once the battery reaches a predefined threshold. Although the review highlighted the lack of USB connectivity, which restricts plug-and-play use with devices expecting a traditional USB UPS handshake, the Ethernet management layer compensates by offering wider network-based communication. However, features such as per-device runtime configuration or selective port control are not yet implemented, leaving shutdown scheduling dependent on firmware updates or future model revisions.

The control and monitoring interface remains minimalistic, relying heavily on UniFi’s centralized GUI rather than onboard interaction. LEDs on the chassis provide a clear visual indication of status—covering power mode, adoption state, and battery level—but all deeper telemetry must be accessed through UniFi Network. Once paired, users can also configure email or push notifications for voltage irregularities, battery health alerts, and firmware updates. It is important to note that the current firmware does not support pure sine wave operation or lithium-ion battery upgrades, though UniFi has stated that future models will expand the portfolio to include these higher-end options. In its present form, the UPS-Tower and UPS-2U focus on stability, ease of deployment, and unified management within a single software environment, making them efficient for UniFi users seeking automation without added complexity.

The UniFi UPS-Tower UPS Review – Conclusion and Verdict

The UniFi UPS-Tower and UPS-2U represent the brand’s first foray into managed backup power systems, designed primarily to extend the reliability and consistency of the broader UniFi ecosystem. Both units share the same line-interactive architecture, simulated sine wave output, and Ethernet-based monitoring, offering a predictable and easily managed experience for users already invested in UniFi infrastructure. Their minimalist design, compact footprint, and seamless adoption through the UniFi Network Controller make them suitable for environments where simplicity, remote monitoring, and integration outweigh the need for advanced runtime management or pure sine wave output. For most small network or NAS setups, either model will provide adequate protection during short outages and brownouts, while ensuring systems are safely powered down when battery capacity is depleted.

However, their appeal remains closely tied to the UniFi ecosystem. The absence of USB connectivity, PoE passthrough, and lithium-ion battery options limits their usefulness in heterogeneous or high-performance environments. Users seeking pure sine wave support, longer runtimes, or advanced per-device control will likely need to wait for the next generation of UniFi UPS models, which the company has already suggested will expand to include these options. As they stand, the UPS-Tower and UPS-2U are well-built, tightly integrated, and cost-effective for UniFi users, but less compelling for those operating outside that ecosystem. They function precisely as intended: reliable, network-aware power backups for UniFi-managed systems, providing foundational stability rather than feature innovation.

C’est fou car pendant que vous êtes encore en train de vous galérer avec votre bon vieux Windows, sachez que 6% de vos voisins sont en train d’utiliser Linux en totale détente. C’est en tout cas ce que remonte cette étude du CNLL et d’Abilian qui explique qu’on est maintenant 2,2 millions d’utilisateurs Linux en France.

D’après les données de Cloudflare Radar analysées par Abilian , l’usage personnel de Linux (4,3%) est deux fois plus élevé que l’usage professionnel (2,15%) ce qui montre bien que les gens font du Linux à la maison par choix, et non pas par obligation. D’ailleurs cette tendance s’accentue encore plus le weekend où l’usage des ordinateurs se fait essentiellement à titre personnel.

Comme le dit Stefane Fermigier, co-président du CNLL, dans son communiqué, “Ces chiffres sont une claque aux préjugés !”. Et il a raison même si on est encore en dessous de la moyenne Européenne. Celle-ci est de 3,7% de part de marché Linux alors que la France est à 3,1%. Les champions c’est la Finlande avec 7,1%, suivie de l’Irlande (5,3%) et de l’Allemagne (5,2%), donc on a encore une petite marge de progression.

Mais rassurez-vous, ce n’est pas qu’une question de compétence technique. C’est culturel car là-bas, utiliser Linux c’est normal, alors qu’ici c’est encore un peu un truc de geekos rebelles. Mais c’est en train de changer vite, et vous savez grâce à quoi ? Les jeux vidéo, pardi !! Avec Proton et Steam qui permettent de faire tourner les jeux Windows sur Linux, plein de gamers ont sauté le pas. C’est un des facteurs majeurs de la croissance mondiale de Linux qui atteint maintenant 4,55%.

Le gaming sous Linux c’est le cheval de Troie parfait car les mecs installent Ubuntu pour jouer et découvrent qu’il peuvent aussi bosser dessus, faire de la création, gérer leur vie numérique sans passer par Microsoft…. C’est une vraie prise de conscience.

Aux États-Unis, par exemple, Linux vient de passer la barre des 5% de parts de marché desktop. C’est une progression de 2 points en 2 ans, ce qui est énorme ! En plus avec la fin annoncée de Windows 10 qui force les gens à jeter à la poubelle leur ordinateur qui fonctionne s’ils veulent passer sous Windows 11, ça va encore augmenter je pense… Car Linux (ou ce logiciel magique ) est une solution anti-obsolescence incroyable !

Du coup, la CNLL milite pour qu’en France, on ait une vraie politique “Open Source & Sovereignty First” dans les marchés publics ce qui n’est pas gagné car l’Etat est gangréné par Microsoft… La CNLL veut notamment qu’on applique enfin l’article 16 de la loi République Numérique qui favorise le logiciel libre. Une pétition européenne propose même de créer un “EU-Linux” pour les administrations publiques. Imaginez toutes les mairies et préfectures sous Linux ! Ce serait cool !

Voilà, avoir Linux sur sa machine perso à la maison, c’est comme avoir un potager bio ou manger moins de viande… on le fait pour soi, par conviction, sans forcément militer. Et que Linux devienne mainstream c’est vraiment mon rêve car on n’en peut plus des zélites à barbes qui se définissent humainement de part leur OS, en regardant de haut les “autres”, les noobs, sans jamais leur tendre la main. Le jour où Monique de la Mairie ou Francis de la médiathèque sauront se démerder seuls sous Linux, je pense que leur égo en prendra un coup. Ils passeront alors sous BSD ou un truc encore plus techy parce que ça c’est un VRAI OS DE BONHOMME… ahahahah.

Puis en vrai, y’a encore plein de machines sous Linux que l’étude n’a probablement pas comptabilisées… On a tous chez nous des Raspberry Pi dans des tiroirs, des vieux PC reconverties en NAS, des petits serveurs perso…etc. Donc le vrai chiffre est sûrement bien plus élevé.

Alors oui, c’est vrai, on est encore loin des 72,5% de Windows, mais la tendance est claire. Linux grandit, doucement mais sûrement. Et surtout, c’est un mouvement très doux, très organique, qui n’est pas poussé par une méga-corpo, mais juste par des gens qui veulent reprendre le contrôle de leur ordinateur (et qui en ont marre de payer pour rien aussi, je pense…)

Voilà, donc la prochaine fois que vous croiserez quelqu’un dans une soirée, demandez-vous s’il fait partie des 6% de Français sous Linux ? Vous vous ferez plein de nouveaux amis ;-)
