Supermicro PWS-751P-1R 750W redundant platinum power supply

SKU CH-EXGC-FADR6

1U redundant platinum 750W supply with PMBus monitoring for server racks

  • 750 W output powers dense 1U servers
  • Platinum efficiency reduces energy waste and heat
  • Redundant design keeps systems running during failures
  • PMBus monitoring enables remote power management
  • Plug-and-play installation simplifies server deployment

750W Redundant Platinum PSU

The Supermicro PWS-751P-1R is a 750 watt redundant power supply built for 1U server chassis. It delivers platinum efficiency and includes PMBus monitoring for remote management. The unit is designed for high-density compute environments requiring continuous uptime. Its single-output architecture simplifies power distribution in compatible racks.

1U Redundant Form Factor

The critical specification is the 1U redundant form factor which only fits server chassis with matching hot-swap bays. Standard ATX cases cannot accept this module because the mechanical latch and connector layout differ. Buyers must verify their chassis supports redundant 1U supplies before ordering. This unit will not work in desktop towers or workstations without a dedicated redundant cage.

PMBus Monitoring Integration

The supply communicates status data through PMBus so management controllers can track voltage, current and temperature. This telemetry frees administrators from manual checks and enables automated alerts. The plug-and-play interface allows quick replacement without tools or cable routing. Systems lacking a compatible baseboard management controller cannot use the monitoring features.

Highlights

  • 750 W output powers dense 1U servers
  • Platinum efficiency reduces energy waste and heat
  • Redundant design keeps systems running during failures
  • PMBus monitoring enables remote power management
  • Plug-and-play installation simplifies server deployment

Questions about this item

What does the 750 watt rating mean when the supply is installed in a 1U server?

The supply provides a single 750 watt output in a 1U form factor so it fits the standard redundant bay and delivers full rated power to the system components.

How does the PMBus interface work with the supply and what does it let you monitor?

PMBus gives digital access to voltage, current, temperature and fan speed readings so management software can track the power supply health in real time.

What physical space and mounting does the 1U redundant unit need in the chassis?

It occupies a standard 1U redundant power supply slot and slides in from the front or rear depending on the server chassis design.
