HPE 800W Flex Slot Platinum Hot Plug Low Halogen Power Supply Kit

The HPE P38995-B21 is an 800 watt Flex Slot Platinum hot plug power supply kit created for administrators who run HPE ProLiant Gen10, Gen10 Plus, Gen11, and select Apollo or Alletra servers. It slides into the Flex Slot bay without tools and immediately delivers reliable power with a 94 percent efficiency rating, which helps lower energy bills while keeping performance steady.

This unit accepts a wide input range from 100 to 240 volts AC, so it adapts easily to different data center power infrastructures. Because it supports hot-plug replacement, you can swap the supply during maintenance or an upgrade without bringing down critical workloads, a benefit that keeps service levels intact and users unaffected.

Its compact Flex Slot footprint leaves more internal room for additional storage drives or expansion cards, and the low halogen design supports environmental compliance initiatives. Backed by the same service coverage as your supported HPE server, the P38995-B21 integrates smoothly into existing management routines, making it a practical choice for IT teams that value efficiency, uptime, and straightforward compatibility.
