Power module for 1U servers

The Supermicro PWS-654-1R is a 650 W DC input redundant power module designed for 1U rackmount servers. It delivers reliable power density in a compact form factor suited to high-availability environments.

Compatibility check before ordering

Verify that your chassis accepts 1U redundant power modules and provides a DC input source matching the unit's requirements. Confirm the physical slot dimensions align with the module's 1.6" height and 2.1" width before installation.

Integration into a redundant build

The module slides into a compatible redundant power cage, sharing load with a second unit for failover protection. Its approximate 10 lb weight is supported by the cage rails, freeing internal space that a monolithic supply would occupy.
