What this power supply is and who it is for

The HPE 865414-B21 is an 800W Flex Slot Platinum hot-plug server power supply built for HPE ProLiant Gen10 and 300 Series Gen9 systems. It delivers up to 96 percent efficiency with 80Plus Titanium certification to lower data centre power waste. The 25 percent smaller form factor frees space for additional server options while supporting tool-less replacement during operation.

What to check on your existing setup before ordering

Verify that your server chassis accepts Flex Slot power supplies and that the unit matches the 230 V AC input rating shown in the supplier title. Confirm the kit’s 1400 W rating aligns with your redundancy or capacity plan and that the 48 V DC input option is not required for your configuration. Ensure the hot-plug bay and backplane are compatible with this form factor.

Thermals noise and power draw in normal use

High 96 percent efficiency reduces waste heat, easing cooling demand inside the rack. Hot-plug design allows removal without shutting down the server, limiting thermal disruption during maintenance. The low-halogen construction meets environmental guidelines while the compact size improves airflow density. Power draw scales with load up to the 800 W rating per unit.

Questions about this item

What comes in the 865414-B21 kit and what must be purchased separately?

The kit includes the 800W Flex Slot Platinum power supply unit; a supported HPE server chassis and an appropriate AC power cord are required separately.

Which version should I choose between the 800W Platinum and the higher-wattage options?

Select the 800W Platinum unit when your configuration draws up to 800W and you want 96% efficiency with 80Plus Titanium certification; move to the 1400W or 1600W models only if the total load exceeds 800W.

What does the 96% efficiency figure mean once the supply is installed in a server?

At typical load the unit converts 96% of AC input to DC output, so only 4% becomes heat, lowering electricity cost and reducing cooling demand in the rack.
