Supermicro Compatible 300W Server PSU

This PS2/ATX power supply is built for Supermicro systems that require a 300W unit. It fits directly into compatible server chassis without adapters. System integrators maintaining existing Supermicro infrastructure will find it a direct replacement part.

Single Fan Cooling at 300W Load

The internal fan spins to move air across the components while delivering the rated 300W output. Acoustic output rises with load but remains typical for 1U server power supplies. Power draw from the wall matches the DC load plus normal conversion losses for this class.

Questions about this item

How is the YINGHUA PWS-305-PQ installed in a Supermicro server, and what step is often missed?

Slide the 300W unit into the PS2/ATX bay until the latch clicks, then secure the retention screw; the step often missed is fastening that screw, which prevents the supply from unseating under vibration.

What maintenance or replacement will the YINGHUA PWS-305-PQ need later?

The internal fan is the only moving part; plan to clean dust from its intake every few months and replace the fan assembly if bearing noise appears, otherwise the 300W supply itself has no user-serviceable components.
