High-density server power supply

The Supermicro PWS-1K28P-SQ delivers 12V output at 83A with a 5V standby rail at 4A. It uses a 46pin main connector and measures 2.99" x 1.57" x 14.17". This unit is built for dense server and storage deployments requiring high current in a compact form factor.

Hot-swap redundancy integration

The supply fits Supermicro 1U, 2U, 3U and 4U chassis and supports hot-swappable replacement. It works in redundant configurations such as 1+1+1, 1+2 or 2+2 setups alongside battery backup modules. The design frees internal space by matching the standard redundant AC supply footprint of 76W x 360D x 40.4H mm.

Mission-critical uptime focus

This product suits operators who need continuous power for critical workloads and can deploy matching Supermicro chassis. Buyers without compatible redundant bays or those needing different voltage rails should look elsewhere.
