HP Flex Slot 500W Server Power Supply

The HP Flex Slot 500W Platinum power supply fits HP ProLiant Gen10 Performance Servers using the common Flex Slot electrical and physical design. It supports hot-plug, tool-less installation so administrators can add or replace units without shutting down the server. The 500 watt output lets you right-size power for specific server configurations.

AC Input Range and Flex Slot Interface Limits

The unit accepts 100 to 240 volt AC input across global mains voltages. Its proprietary Flex Slot form factor only works in bays built to the same electrical and mechanical specification; standard ATX, EPS or redundant chassis slots will not accept it. Efficiency certification at Platinum level reduces waste but does not change the connector or mounting constraints.

Server Generation and Bay Compatibility Check

Verify that the target server is a ProLiant Gen10 Performance model with an available Flex Slot bay before ordering. Confirm the chassis supports hot-plug power supply replacement and that the total installed power budget covers all components. The part number 866729-001 identifies this specific kit for ordering accuracy.

Questions about this item

Which Flex Slot power-supply capacity should I choose for my ProLiant Gen10 server?

Select the 500 W unit when your server configuration stays within that output; higher-wattage Flex Slot models exist for denser builds, while lower ones save cost on lighter loads.

What does the 500 W rating deliver inside a Gen10 chassis?

It provides up to 500 W of platinum-efficiency power across the 100-240 V AC range, with hot-plug redundancy so the server stays online during replacement.

How does the Flex Slot interface limit what I can connect?

The proprietary Flex Slot form factor only fits HPE ProLiant Gen10 bays; it cannot be used in standard ATX cases or non-HPE hardware.
