What this power supply replaces

The Qnap PWR-PSU-320W-FS01 is a 320W proprietary power supply built for specific Qnap systems. It is intended for owners of compatible Qnap hardware who need a direct replacement unit. It is not for builders assembling a standard ATX PC or anyone needing a modular cable set.

The deciding specification

This unit uses a proprietary form factor and connector layout defined by Qnap, not an industry-standard ATX pinout. Compatibility is therefore limited to the exact Qnap models that call for this part number. If your chassis expects a standard ATX supply, this unit will not fit or connect.

How it fits into the system

The supply installs directly into the designated bay of the supported Qnap enclosure and draws AC power from the wall inlet. It delivers the 320W rated output to the internal backplane and board without extra cables. No adapter harness or mounting bracket is required when used in the correct Qnap chassis.
