QNAP 250W Delta Power Supply - PWR-PSU-250W-DT02

QNAP PWR-PSU-250W-DT02 250W Delta Power Supply

Overview

The PWR-PSU-250W-DT02 is a 250W Delta-manufactured internal power supply sold by QNAP as a direct replacement unit. At 250W, it delivers enough headroom for multi-drive NAS enclosures where a failed or degraded PSU needs to be swapped without taking the chassis offline for an extended period. If you're running a QNAP unit that shipped with a Delta PSU and need a like-for-like replacement, the PWR-PSU-250W-DT02 is the factory-matched option rather than a generic third-party substitute.

Compatibility

This power supply is a QNAP OEM part intended for specific NAS enclosures that ship with a 250W Delta PSU. QNAP does not publish a universal compatibility list for this SKU on its product page — verify your chassis model against the PSU form factor and wattage rating before ordering. Common candidates are mid-range tower and rackmount NAS units in the 4-to-8 bay range that specify a 250W internal supply. Cross-reference your unit's service documentation or the label on the installed PSU to confirm the Delta model number matches before purchase.

Installation Notes

Replacement PSU installations on QNAP NAS enclosures typically require powering down the unit completely and disconnecting all drives before swapping the supply. The Delta form factor used in this family is not hot-swappable in standard tower configurations — plan for a maintenance window. Confirm the connector pinout and physical dimensions match your chassis before installation; a mismatched PSU will not seat correctly and can cause damage.
