Dell RH8P5 460W PSU for XPS Desktops

This is a new 460 watt power supply built by Dell for the XPS 7100, 8300 and 8500 desktop lines. It replaces the original unit when it fails or when a rebuild requires a factory-rated spare. The part number RH8P5 matches the OEM specification exactly. It is not for systems outside the listed XPS models.

Proprietary Dell pinout and chassis fit

The module uses Dell's own connector layout and physical mounting tabs, so it slots into the XPS chassis without adapters or cable mods. Standard ATX cables will not connect to the motherboard. Builders who need a standard ATX supply for a custom case cannot use this unit.
