QNAP 300W Power Supply Unit Single Delta - PWR-PSU-300W-DT01

QNAP PWR-PSU-300W-DT01 300W Desktop Power Supply Unit

Overview

The PWR-PSU-300W-DT01 is a 300W single-unit desktop power supply designed as a direct replacement or spare for compatible QNAP NAS enclosures. At 300W, it delivers sufficient headroom for drive-dense desktop NAS configurations without requiring a redundant PSU chassis — keeping the install compact and straightforward. If you're servicing an existing QNAP unit or stocking a field-replacement spare, this is the component to pull.

Compatibility

This PSU is designed for specific QNAP desktop NAS enclosures that accept the DT01 power supply form factor. Verify your enclosure's PSU specification against the PWR-PSU-300W-DT01 before ordering — QNAP offers multiple PSU variants (wattage and form factor) across its NAS lineup, and cross-model substitution is not supported. Consult the QNAP storage catalog or your enclosure's hardware manual to confirm fit. This unit is not compatible with rack-mount NAS or tower enclosures that require higher-wattage or redundant PSU configurations.

Installation Notes

Replacement PSU installation should be performed with the unit powered down and unplugged. Verify connector pinout and physical form factor match the original unit before seating. No tools beyond basic hand tools are typically required for PSU swap on desktop QNAP enclosures, but confirm the enclosure service manual for any model-specific steps. This is a single (non-redundant) supply — if your deployment requires hot-swap or fault-tolerant power, evaluate QNAP enclosures with dual-PSU bays and a matching redundant supply instead. For broader NAS storage configuration guidance, review your enclosure's power requirements against installed drive count and expansion cards before commissioning.
