QNAP 300W Single Power Supply

The QNAP PWR-PSU-300W-DT01 is a 300 watt single power supply module designed for administrators who run QNAP rackmount NAS systems and want a dependable power source they can install or swap without hesitation. Whether it functions as the main supply or sits in a redundant bay, the unit slides into place and connects through QNAP proprietary power interface, so there is no need for tools or extended downtime.

Because the module supports hot plug operation, you can replace a failing supply in a live system while critical workloads continue to run. An integrated air cooling channel directs heat toward the enclosure fans, helping the NAS maintain safe operating temperatures during sustained transfers or heavy virtualisation tasks.

The power supply is compatible with the TS-1273U-RP, TS-877XU-RP, TS-883XU-RP, TS-1277XU-RP, TS-1283XU-RP, TVS-872XU-RP, and TVS-1272XU-RP. Keeping one of these modules on hand allows a single spare to cover a rack populated with different models, which simplifies inventory planning for data centres, branch offices, and managed service providers that cannot afford unexpected outages.
