Product information

Description

The HPE 865408R-B21 500W Grey power supply unit is a server-grade PSU compatible with HPE ProLiant DL360 Gen10+ systems. It delivers up to 500 W of total power with an AC input range of 100–240 V and an efficiency of 94% (80 PLUS Platinum), providing reliable power delivery in a compact, hot-pluggable form factor. Its reduced size compared with previous-generation HPE common slot supplies frees internal space for additional server components while supporting standard serviceability and spare-part strategies across ProLiant Gen10 and ProLiant 300 Gen9 families.

Advantages

This 500W HPE power supply offers high conversion efficiency (94%) under typical loads, which lowers server power draw and reduces waste in rack environments. The compact design is approximately 25% smaller than earlier HPE common slot units, enabling more internal room for upgrades. The unit supports tool-less, hot-plug access for fast replacement and maintenance, and its compatibility with multiple ProLiant generations simplifies spare management and data center operations.

Suitable for

  • HPE ProLiant DL360 Gen10+ server installations
  • Replacement or spare power supply for ProLiant Gen10 and ProLiant 300 Gen9 servers
  • Data center racks where high-efficiency 500W PSUs are required

How to use

Install the PSU into a compatible HPE ProLiant server chassis by sliding the unit into the designated power bay until the tool-less latch engages. Connect the AC mains cable to the PSU input rated for 100–240 V. For service or replacement, use the hot-plug procedure supported by the server: power down the appropriate supply if N+1 redundancy is not present, or simply remove and replace the unit while the server remains operational if redundancy allows. Verify that the server firmware and management tools recognize the new PSU after insertion.

Usage recommendations

Use this 500W HPE power supply as part of a matched set for redundant configurations where possible. Ensure adequate airflow in the chassis and monitor power and thermal metrics via HPE management utilities to maintain efficiency and longevity.
