Redundant 720W server power supply

This hot-plug redundant unit delivers 720W to Supermicro chassis that accept a gold-finger form factor. It targets administrators building or expanding 1U and 2U systems where an N+1 power architecture is required.

Tool-less hot-plug installation

The module slides into a compatible bay and locks with a thumb-screw latch; no cables are routed inside the chassis. The only common issue is attempting to fit it into a non-redundant backplane or a vendor-specific cage that uses a different keying.

100–240 V AC input with 80 PLUS Gold efficiency

The supply auto-ranges across 50/60 Hz mains and maintains better than 90% efficiency at typical loads. It cannot operate from DC sources, and the gold-finger connector limits use to Supermicro platforms that implement the matching power bus.

Questions about this item

How do I confirm the PWS-721P-1R is delivering 720W after installation?

Check the server management interface for +12V rail readings near 59A and +5VSB near 4A, and verify the unit reports > 90% efficiency under load.

What ships with the PWS-721P-1R and what must I source separately?

The unit includes the redundant 720W module with its Gold Finger Connector; a C13 power cord for 100-240V input and the compatible server chassis backplane are not included.

Which PWS-721P-1R version suits a 2U chassis needing 80PLUS Gold efficiency?

This single model provides 720W, 80PLUS Gold certification, and the 13.58" x 2.99" x 1.58" form factor designed for redundant bays in supported Supermicro chassis.
