Redundant 700 W server supply

The Supermicro PWS-702A-1R delivers 700 W of redundant power in a slim 13.58" x 2.99" x 1.58" form factor. It fits standard hot-swap bays for rackmount servers that require continuous uptime. A single internal fan provides airflow across the module.

Sustained load on the +12 V rail

The +12 V rail is rated for 58 A continuous output, while the +5 V and +3.3 V rails supply 30 A and 24 A respectively. The 5 V standby rail provides 4 A for management controllers. All rails maintain regulation during extended operation without short-term peak inflation.

ATX/EPS connector limits

The unit follows the redundant PSU form factor and pinout defined by the SSI EPS specification. Cable reach and connector count are fixed by that standard, so builders must verify their backplane and motherboard headers match before installation.

Questions about this item

How loud is the single fan in this 700W supply when the system runs continuously?

The unit uses one internal fan; noise level varies with load and chassis airflow, so plan for typical server-grade acoustic output.

Which motherboard power connectors must my board provide for the PWS-702A-1R to function?

This redundant supply requires a compatible 12V main connector, 5V and 3.3V rails, plus a 5VSB standby line — verify your backplane matches these outputs.

Will the 58A 12V rail support older drives and expansion cards I keep in the same chassis?

The +12V@58A, +5V@30A and +3.3V@24A rails deliver ample current for legacy HDDs, PCI cards and fans that draw from those voltages.
