HPE X312 1000W server power supply

This proprietary internal unit converts 110 V AC or 220 V AC mains input into a regulated 54 V DC output rated at 1000 W. It is designed specifically for the HP E3800 Switch Series and Data Vault X312 server platforms.

Sustained-load behaviour

The supply delivers its full 1000 W continuously across the 100-240 V AC input range without derating. Its internal form factor relies on the host chassis airflow for cooling under prolonged operation.

Upgrade context

This unit replaces a failed or missing X312 power module in the compatible switch or server. The jump is worth it when the existing chassis requires a direct 54 V DC source at this power level and no alternative form factor fits.

Questions about this item

How much heat and fan noise should I expect from the 1000 W X312 supply when it runs continuously in a Data Vault X312?

The unit delivers 1000 W at 54 V DC from 110 V AC or 220 V AC input; typical server supplies of this class use internal fans that ramp with load, so expect audible airflow under full load.

Which specific HPE chassis or switch must I already own for this J9580A module to fit and power up?

It is listed as compatible with the HPE Data Vault X312 server and the E3800 Switch Series; the proprietary form factor will not fit standard ATX or other vendor bays.

Can I keep my existing E3800 switch and add this 1000 W supply as a redundant or replacement unit?

Yes, the X312 1000 W supply is validated for the E3800 Switch Series, so it can serve as a hot-swap replacement or redundant module in that platform.
