HP X312 1000W 54VDC power supply

This proprietary 1000 watt unit converts 100 to 240 volt AC mains input into a regulated 54 volt DC output. It is built for the HP E3800 switch series and Data Vault X312 server where a direct-replacement internal module is required.

Thermals noise and power draw

The supply accepts both 110 volt and 220 volt AC sources across the full 100 to 240 volt range, delivering up to 1 kilowatt at the 54 volt rail. Internal cooling and acoustic profile are managed by the host chassis, so thermal and noise behaviour follows the switch or server design rather than the module alone.

Bundled accessories and software

No extra cables, mounting brackets or configuration utilities are included with the module. Installation relies on the existing chassis slot and backplane connectors of the compatible E3800 or X312 hardware, so nothing additional needs to be sourced or configured.

Questions sur cet article

How is the HP X312 1000W power supply installed in the Data Vault X312 server, and what step is often missed?

Slide the unit into the internal bay until the latch clicks, then secure the retention screw; the step often missed is tightening that screw, which prevents the supply from unseating under vibration.

What maintenance or replacement will the HP J9580A power supply need over its service life?

The internal fan bearings are the primary wear item; plan to replace the entire supply when airflow drops or bearing noise appears, as the proprietary form factor does not allow fan-only servicing.

What is the first limit reached when the HP 0957-2312 runs at full 1000W output continuously?

Thermal protection engages first; sustained 1 kW load at 54 V DC raises internal temperatures until the over-temperature circuit shuts the unit down to prevent damage.
