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.

Questions about this item
What server form factor does the Flex Slot design fit?
The Flex Slot power supply uses a common electrical and physical design that allows tool-less installation into HP ProLiant Gen10 Performance Servers.
How do you install the power supply and what step is often missed?
Slide the unit into the Flex Slot bay until the latch clicks; the hot-plug feature means the server does not need to be powered down, but forgetting to engage the latch is the common error.
When will the 800W Platinum module need replacement?
With 96 efficiency and hot-plug capability, the module can be swapped without downtime; plan replacement when efficiency drops below 96 or after the rated service life of the host server.
