920W Platinum server power supply

The Supermicro PWS-920P-1R delivers 920W of continuous power for rackmount servers and high-density compute nodes. It operates from 110V or 220V AC mains and carries 80PLUS Platinum certification for 94%+ efficiency. The unit includes PMBus monitoring for remote management integration.

+12V rail capacity and headroom

The single +12V rail supplies up to 75A, covering multi-socket CPUs and multiple GPU accelerators within the 920W envelope. A 5V standby rail provides 4A for baseboard management controllers. Loads exceeding the rated output will trigger protection circuits and shut the unit down.

PMBus monitoring and AC input range

PMBus exposes real-time voltage, current and temperature telemetry to the system management bus. The wide 110V to 220V AC input range supports global deployment without manual switching. No redundant hot-swap frame or internal fan speed curves are documented in the supplied data.

Questions about this item

Will the +12V@75A output work with my existing server backplane?

The unit delivers up to 75 amps on the +12 V rail, which is compatible with most standard server backplanes designed for this current rating.

How can I verify the 94%+ efficiency is active after installation?

Use the PMBus interface to monitor real-time input and output power; the reported efficiency should match the 80 PLUS Platinum rating under typical loads.

Does the box include cables or only the PWS-920P-1R power module?

The package contains the PWS-920P-1R power module only; power cables and any mounting brackets must be sourced separately.
