Replacement for HP Media Center

The Replace Power RPSU-C99-20 is a 420W ATX power supply designed as a direct replacement for specific HP Media Center desktops including the m1180n m1270n m1820n m1195c m1264n and m1265c models. It accepts switchable 110V or 220V input and uses an 80mm fan for cooling. Grey in colour and weighing 0.1, it targets owners of those legacy systems needing a functional unit.

Capacity and headroom for legacy builds

At 420W this unit comfortably handles the original components found in the listed HP Media Center chassis such as period processors integrated graphics and a modest drive count. The single 12V rail and combined output limit headroom for modern discrete graphics cards or high core count CPU upgrades. It runs out when a build demands sustained loads above its rated maximum or requires additional PCIe power connectors not present.

Connector mix and upgrade limits

The harness includes a 15 inch SATA connector a 14 inch 20 plus 24 pin ATX motherboard connector a 14 inch 12V ATX connector two 15 inch large peripheral connectors two 6 inch large peripheral connectors and one 6 inch small peripheral connector. This covers the factory devices in the target models. The jump is worth it when the original supply has failed or shows instability. It is not for builders who need dedicated PCIe power for a graphics card or more SATA ports than the single provided connection.

Questions about this item

Will the RPSU-C99-20 fit my older HP Media Center m1180n without modifying the case?

Yes, the unit is built as a direct replacement for the HP Media Center m1180n, m1270n, m1820n, m1195c, m1264n and m1265c models and uses the standard ATX form factor.

How can I verify the 80 mm fan is spinning correctly after I install the supply?

Power on the system and listen for the 80 mm fan; airflow should be felt at the rear grille and the PSU should stay cool under load.

Which cables come attached to the RPSU-C99-20 and what must I source separately?

The box includes one 15-inch SATA connector, one 14-inch 20+4 pin ATX connector, one 14-inch 12V ATX connector, two 15-inch and two 6-inch large power connectors, plus one 6-inch small power connector; no extra cables are required for a typical HP Media Center rebuild.
