QNAP 250W Delta Power Supply - PWR-PSU-250W-DT04

QNAP PWR-PSU-250W-DT04 250W Desktop Power Supply

Overview

The PWR-PSU-250W-DT04 is a 250W desktop-form-factor power supply designed as a direct replacement or spare for compatible QNAP NAS enclosures. When a failing PSU takes a NAS offline — whether in a surveillance recording deployment or a small-business file server — having a factory-matched replacement on hand eliminates the guesswork of sourcing a third-party unit that may not meet the original voltage, connector, or wattage profile.

Compatibility

This unit is a QNAP-branded PSU intended for compatible QNAP desktop NAS enclosures that accept a 250W power supply in the DT04 form factor. Because QNAP uses several distinct PSU connector layouts and wattage tiers across its enclosure lineup, confirm your specific model's PSU specification before ordering — a 250W unit will not substitute for an enclosure rated for a higher wattage supply, and connector pinouts vary by chassis generation. Consult the QNAP compatibility matrix or your enclosure's hardware manual to verify this part number is the correct replacement for your unit.

For environments running multiple NAS units in a network video recording or storage cluster configuration, stocking a spare PSU per chassis tier reduces downtime exposure when primary units fail.
