QNAP 300W Power Supply Unit Delta - PWR-PSU-300W-DT02

QNAP PWR-PSU-300W-DT02 300W Desktop Power Supply Unit

Overview

The PWR-PSU-300W-DT02 is a 300W replacement power supply unit designed for compatible QNAP desktop NAS enclosures. When an original PSU fails or degrades, swapping it with a direct replacement keeps the enclosure running without chassis changes or makeshift adapters — the right call for any deployment where downtime means lost access to surveillance recordings, shared storage, or backup repositories.

Compatibility

This PSU is a QNAP-sourced unit intended for compatible QNAP desktop NAS enclosures rated for a 300W power supply. Verify your specific enclosure model against QNAP's compatibility documentation before ordering — QNAP produces multiple PSU variants across its desktop lineup, and connector layout, form factor, and wattage requirements vary by chassis. Do not assume cross-compatibility with tower or rackmount enclosures, which use different PSU form factors and connector sets.

Installation Notes

Power down the enclosure completely and disconnect all cables before replacing the PSU — there are no hot-swap provisions on desktop QNAP units. Discharge residual power by pressing the power button after unplugging. Match all internal connectors carefully before seating; forcing mismatched connectors risks damage to the mainboard. Retain the original PSU until the replacement is confirmed operational.
