HP 800W Flex Slot Hot-Plug Platinum Low Halogen Power Supply 865414-B21

800W Flex Slot Hot-Plug Power Supply

This 800 watt server power supply uses the HP Flex Slot form factor and supports hot-pluggable, tool-less installation in compatible ProLiant Gen10 Performance Servers. It operates on a 100 to 240 volt input range and carries an 80 PLUS Platinum efficiency rating of 96 percent. The low halogen design meets environmental requirements for modern data centres.

Upgrading from Lower Capacity Flex Slot Units

Replacing a lower wattage Flex Slot module with this 800 watt unit adds headroom for additional processors, memory or accelerator cards without changing the server chassis or cabling. The jump is worth it when the existing power budget limits further configuration growth or when redundancy policies require higher per-module capacity. Hot-plug capability allows the swap without scheduled downtime.

Capacity and Headroom for Dense Compute

An 800 watt module comfortably handles dual processor configurations with large memory populations and multiple storage controllers in a single server node. At 96 percent efficiency, waste heat and operating cost stay low even under sustained load. The unit runs out of headroom when the combined component draw approaches the 800 watt maximum, requiring either a second module for redundancy or a move to a higher capacity power shelf.
