Replacement PSU for HP Pavilion

The Replace Power RPSU-C99-10 is a 420W ATX power supply built to fit HP Pavilion a752n a762x a767c a775c a820n a824n a830n a832n desktops. It targets owners of those systems who need a direct swap for a failed or ageing unit. The grey enclosure uses a single fan for airflow. Input voltage is switchable between 110V and 220V.

Sustained load behaviour

Rated at 420W, the unit delivers continuous power through one 15-inch SATA connector and one 14-inch ATX power connector. The 80mm fan runs constantly to move heat away from the internal components during extended use. No efficiency certification or thermal protection details are provided in the specifications.

Installation notes

The ATX form factor aligns with the mounting holes and connector layout of the listed Pavilion models. Swapping the unit requires removing the old supply, fitting the new one, and attaching the two provided cables. Builders working on non-HP chassis or systems needing additional SATA or PCIe connectors will find this unit unsuitable.

Questions about this item

How loud does the single 80mm fan get when the 420W RPSU-C99-10 runs all day?

The unit uses one 80 mm fan for cooling; noise level varies with load and case airflow.

Which existing cables or connectors must my system already have to use the 15-inch SATA and 14-inch ATX leads on this PSU?

Your motherboard needs a standard 20/24-pin ATX socket and the drives need SATA power ports.

Will the switchable 110V/220V input on this grey ATX unit work safely with the original wiring in an HP Pavilion a752n or a830n?

Yes, the voltage selector matches the mains range used by those Pavilion models.
