Replace Power RPSU-C95-4 400W ATX power supply

Replacement for HP Pavilion desktops

This 400 watt ATX power supply replaces the original unit in HP Pavilion 763n 764c 8655C a1514n a1542n a350n and a450n systems. It provides a 20+4 pin motherboard connector that fits both 20 pin and 24 pin boards along with a 4 pin 12 volt CPU connector. Three SATA 15 pin connectors two Molex 4 pin connectors and one floppy 4 pin connector cover most internal peripherals. Builders restoring or upgrading these legacy desktops will find a direct fit.

Check connector count and physical space

Verify that your motherboard uses a 20 pin or 24 pin main power socket and that the 4 pin 12 volt CPU plug is present. Count your SATA drives and Molex devices to ensure the three SATA and two Molex leads are sufficient. The unit measures 5.8 by 3.37 so confirm the chassis cavity can accommodate those dimensions. No other form factor or mounting standard is addressed by this model.

Single fan cooling with protection features

One fan draws air through the grey enclosure to manage thermals during typical desktop workloads. The design includes high efficiency conversion low ripple and noise output and over voltage protection on the output rails. These features help maintain stable voltages and limit acoustic output in normal use. The supply weighs 0.1 and carries no additional certifications mentioned in the data.
