QNAP 550W Power Supply Unit (Delta)

The QNAP PWR-PSU-550W-DT01 is a 550 watt ATX power supply built for select QNAP NAS enclosures. It supplies steady power through standard ATX connectors and relies on an internal fan that moves air efficiently to keep temperatures under control.

The unit fits directly into the power bay of the TS-1886XU-RP, TL-R1620Sep-RP, TS-1673AU-RP, TS-h3088XU-RP, and TL-R1620Sdc. Installation is straightforward, and no specialized tools are required. Administrators can deploy it as the primary power source or add it to a redundant configuration when continuous service is critical.

Keeping a spare on the shelf is a practical safeguard for branch offices, data centers, and managed service providers that rely on these NAS models for everyday backups, file sharing, or surveillance recording. If a failure occurs, the swap takes only minutes, which helps avoid unplanned downtime and protects data access.

• 550 watt power capacity for sustained NAS workloads
