Supermicro PWS-920P-SQ 920W 1U server power supply

SKU CH-KT5Q-QJZRG

A 920 W 1U redundant power module with PFC and PM Bus for Supermicro server chassis

  • Supply voltage110 V AC 220 V AC
  • Product typePower Module
  • 920 W output powers dense 1U server racks
  • 110 V and 220 V AC input suits global deployments
  • Active PFC corrects power factor for efficient draw
  • PMBus interface enables remote monitoring and control
  • Hot-swap 1U module fits redundant backplane configurations

920W 1U redundant server power supply

The Supermicro PWS-920P-SQ delivers 920 watts in a 1U form factor with active power-factor correction and PM Bus monitoring. It accepts 110 V AC or 220 V AC input and is designed for hot-swap replacement in compatible Supermicro chassis. The module integrates with redundant backplane architectures for continuous operation.

Suited for 1U rack servers needing hot-swap

This unit fits builders who require a single 920 W module for 1+1 or N+1 redundant configurations in supported 1U systems. It is not intended for non-redundant desktop builds, towers lacking a matching backplane, or installations that demand higher per-module wattage such as 1000 W or 1200 W units.

Sustained output at rated 920 W with active PFC

Under continuous load the supply maintains its 920 W rating with power-factor correction active, while PM Bus telemetry reports real-time status to the management controller. Hot-swap capability allows replacement without downtime, and the 1U height keeps airflow consistent in dense rack rows. No battery-backup runtime is provided by this module alone.

Questions about this item

Does my Supermicro chassis have the backplane connector this 920W 1U module plugs into?

The PWS-920P-SQ is a hot-swap module that seats directly into a Supermicro redundant backplane; your chassis must include that backplane and a matching 1U bay.

Can I run this 920W unit alongside an older Supermicro supply in the same redundant backplane?

Mixed-wattage modules can share a Supermicro redundant backplane if each unit meets the chassis power budget and both support PM Bus communication.

How do I confirm the PM Bus link is active after installing the 920W module?

The system management interface will show the new module’s model, input voltage and real-time load once PM Bus enumeration completes.
