HP Pavilion 8100 Replacement PSU

This 300 W ATX power supply is built as a direct replacement for the HP Pavilion 8100 desktop. It delivers standard ATX output with a single cooling fan and a grey enclosure. The unit fits the original chassis mounting points and restores reliable power to ageing systems.

Fits Legacy HP Desktops

Owners of the Pavilion 8100 needing a new-old-stock ATX module will find the correct connector set and form factor here. Builders working on modern motherboards requiring a 24-pin main connector or multiple PCIe power leads should look elsewhere because this unit lacks those interfaces.

300 W Output Rating

The continuous 300 W rating is the single figure that determines whether this supply can support your installed components. If the combined load of the CPU, drives and expansion cards exceeds this ceiling the system will become unstable or fail to start.
