HPE 500 W Proprietary Supply

The HPE 515915-B21 is a 500 W proprietary power supply kit designed for compatible HPE server chassis. It delivers multi-output power for internal components in supported enterprise platforms. The unit is supplied new and intended for system builders or IT teams maintaining qualified HPE hardware.

Efficiency and Input Limits

The supply operates at 90 percent efficiency across its load range. It accepts 110 V AC or 220 V AC input, allowing deployment in standard rack environments. The proprietary form factor restricts use to chassis engineered for this specific power supply design.

Chassis Compatibility Check

Verify that the target server lists the 515915-B21 part number in its qualified options list before ordering. The proprietary connector and mounting layout prevent installation in standard ATX cases or non-HPE racks. Confirm the chassis power bay count and redundancy requirements match a single 500 W module.

Domande su questo articolo

Which capacity should I choose for my server?

This kit provides a single 500 W unit; select it when your chassis requires exactly 500 watts of multi-output power.

What does the 90% efficiency rating mean once the supply is installed?

At typical load the unit converts 90% of AC input into usable DC power, so only about 10% becomes waste heat inside the chassis.

What input voltages does the 515915-B21 accept and what does that cap in practice?

It auto-ranges between 110 V AC and 220 V AC, letting the same supply run on standard office or data-centre circuits worldwide.
