Purpose-Built Server Power

The HPE 866729-001 is a 500 W Flex Slot Platinum hot-plug power supply kit designed for specific HPE ProLiant and BladeSystem servers. It targets administrators maintaining or expanding compatible Gen10 rack, tower and blade platforms that require a redundant, high-efficiency power module.

Modular Build and Hot-Plug Operation

The unit uses a proprietary plug-in module form factor that slides directly into the server's Flex Slot bay without cables. Platinum-rated 94 % efficiency reduces waste heat and operating cost, while hot-plug capability allows replacement during uptime, supporting continuous availability in multi-bay configurations.

Direct Replacement for Compatible Gen10 Systems

This kit replaces a failed or missing 500 W Flex Slot unit in listed DL360, DL380, DL120, DL160, DL180, CL2600, CL2800 and BL460c Gen10 models. The upgrade is worthwhile when adding a second supply for redundancy or when an existing module has reached end of life; it does not fit standard ATX chassis or non-HPE proprietary slots.
