420W ATX replacement unit

This Replace Power RPSU-C99-6 is a 420 watt ATX power supply built to fit HP Media Center models including the m1070n, m1072n, m1080n, m1090n, m1095c and m1170n. It also serves as a direct swap for compatible Dell and Compaq desktops that use the same form factor. The grey enclosure holds a single 80mm fan and weighs 0.1 units. A switchable input covers 110V and 220V mains.

Steady 420W delivery

Under continuous load the unit maintains its rated 420W output without relying on short-term peak headroom. The single fan moves air across the internal components to keep temperatures stable during extended work sessions. Voltage regulation stays within ATX limits across the 20-pin or 24-pin main connector and the single 15-inch SATA lead. The 14-inch ATX cable reaches motherboards in standard chassis layouts.

Replaces original HP PSU

This module replaces the factory power supply in the listed HP Media Center systems when the original unit fails or shows voltage drift. The jump is worth it when the existing supply can no longer hold 420W under load or when the 20-pin and 24-pin compatibility is needed for a motherboard upgrade. It is not suited for builds that demand multiple graphics power connectors or higher total wattage.

Questions about this item

How loud does the single 80mm fan run when the RPSU-C99-6 delivers 420W all day?

The unit uses one 80mm fan for cooling; under continuous 420W load the fan will spin at its rated speed, producing typical ATX power-supply noise levels for that form factor.

Which cables must already be present in my HP Media Center m1070n for the 15-inch SATA and 14-inch ATX connectors to work?

The PSU provides one 15-inch SATA power lead and one 14-inch ATX lead that fits both 20-pin and 24-pin motherboard headers; your system only needs the matching SATA drive and motherboard sockets.

Will the switchable 110V/220V input on this RPSU-C99-6 work with the original wiring in an m1095c chassis?

Yes, the input voltage selector lets you match the local mains supply, so the unit drops straight into the existing wiring of the listed HP Media Center models.
