Replace Power RPSU-C99-11 420W ATX power supply

Replacement PSU for HP Media Center

This Replace Power RPSU-C99-11 unit is a direct replacement power supply for HP Media Center models m7467c, m7658n, m7790y, m7470n, m7480n and m7490n. It delivers 420W from a standard ATX form factor with a grey finish. The unit weighs 0.1 kg and uses a single fan for cooling. It suits owners of those specific HP desktops who need to replace a faulty or ageing PSU.

420W output with switchable input

The defining specification is the 420W rated output combined with a 110V/220V switchable input. This voltage selector lets the unit operate on mains supplies in different regions without an external adapter. The 420W capacity determines whether the PSU can support the system’s installed components; buyers should verify their build’s total draw against this figure.

Single 80mm fan cooling

An 80mm fan provides the only active cooling, so acoustic output and thermal headroom depend on that single rotor. The fan draws air through the chassis to dissipate heat generated at the 420W load. No liquid cooling, heat-pipe or semi-passive modes are present. Power draw at the wall will reflect the system’s actual consumption plus the PSU’s own efficiency losses.
