QNAP 800W Delta Power Supply

The QNAP PWR-PSU-800W-DT01 is a factory-original power supply that provides 800 watts of stable power to compatible QNAP rackmount NAS units, including the TS-2477XU-RP, TVS-2472XU-RP, and TS-2483XU-RP. By delivering the exact voltage and current these systems were engineered to use, it helps keep drives spinning, network cards active, and processors working under sustained loads.

This unit is a practical answer for several situations. If an existing power supply has failed, installing the PWR-PSU-800W-DT01 restores the system without the need to replace the entire chassis. Administrators who want an additional layer of protection can add a second identical supply to models that support redundancy, allowing the NAS to keep running even if one unit is taken offline for maintenance or unexpectedly stops working. It also serves as a straightforward upgrade when moving a lightly configured system to a higher drive count or a more demanding workload that requires greater power headroom.

Installation follows the same steps outlined in QNAP’s hardware guide: power down the NAS when required by the model, release the retaining clips, slide out the old module, and slide the new one into the open bay until it clicks into place. Because it is built by QNAP and matched to these enclosures, the fit is precise and the existing power cabling remains untouched.

Whether the NAS is safeguarding virtual machines in a small data center, archiving 4K video in a post-production studio, or recording surveillance footage around the clock, a reliable power supply is the foundation of system uptime. Using the PWR-PSU-800W-DT01 ensures that the electrical side of the equation meets QNAP’s original specifications, so administrators can focus on storage strategies rather than hardware failures.
