Our take on the Supermicro PWS-502-PQ 500-Watts Multi-Output 80-Plus Bronze ATX12V/EPS12V 24-Pin ATX Power Supply for WorkStation

The Supermicro PWS-502-PQ is a 500-watt server and workstation power supply with a 24-pin ATX connector and EPS12V support. It carries 80 Plus Bronze certification, so it is rated for roughly 82% efficiency at typical loads. It is a replacement or spare part for Supermicro workstations and compatible chassis, not a general-purpose retail PSU. Against consumer 500W units it offers server-grade build and fit but fewer modern connectors, no modular cabling and no current ATX 3.0 features.

Questions and answers

Is this a direct replacement for the original PSU in my Supermicro workstation?
Yes. The PWS-502-PQ is the Supermicro part number for this 500W unit, so it matches the original in size, mounting and connectors. Check your chassis model against Supermicro's compatibility list before ordering.
Will it work in a standard desktop PC?
It can power an ATX board through the 24-pin and EPS12V connectors, but it is built for Supermicro chassis. Cable lengths, mounting and airflow are designed around those systems, so a consumer case may need adapters.
Does it support a modern graphics card?
Only within its 500W budget and connector set. It has no 12VHPWR connector and predates ATX 3.0, so high-power cards need adapters and careful load planning.
What efficiency does 80 Plus Bronze mean here?
It is rated at roughly 82% efficiency at 20% and 100% load and about 85% at 50% load. That is below Gold and Platinum units, so it runs warmer and draws a bit more from the wall.
Is the cabling modular?
No. All cables are fixed to the unit, so unused leads stay in the case. Plan cable routing before installing it.
What comes in the box?
The power supply unit itself. Mounting screws and power cords are not included, so reuse the ones from your system or chassis.
