Replacement Power Supply

The Qnap PWR-PSU-100W-DT01 is a 100W open frame power supply designed as an accessory for compatible desktop NAS units. It provides a direct replacement when the original unit fails or a spare is required for maintenance.

Suitable For Direct Replacement

This unit suits administrators who need a like-for-like 100W module for a supported Qnap NAS. It is not for builders wanting higher wattage, different form factors, or power supplies for non-Qnap hardware.

Fits Inside Compatible NAS Chassis

The open frame design slots into the allocated bay of a matching desktop NAS, drawing AC input and delivering the required DC rails to the motherboard and drives. It frees the system from downtime caused by a failed internal supply.

Questions about this item

What QNAP NAS chassis is the PWR-PSU-100W-DT01 designed to fit?

This 100 W open-frame power supply is built as a direct replacement accessory for compatible QNAP desktop NAS units; check your NAS model’s service manual to confirm it accepts the PWR-PSU-100W-DT01 form factor.

Will the PWR-PSU-100W-DT01 power an older QNAP NAS that originally shipped with a lower-wattage supply?

If the older NAS uses the same open-frame mounting pattern and connector layout, the 100 W unit can serve as a higher-capacity replacement; verify the chassis compatibility list before installing.

How can I confirm the PWR-PSU-100W-DT01 is delivering power correctly after installation?

After fitting the supply, the NAS should complete its normal boot sequence, the status LED should show a steady power state, and the system management interface should report stable voltage rails.
