Replacement PSU for eMachines desktops

This Replace Power RPSU-C99-66 unit delivers 420W of ATX power and is built to fit eMachines W2925 W3115 W3118 W3050 W2260 W3080 systems. It accepts 110V or 220V input via a manual switch and uses a grey chassis with a single 80mm fan. The 20+4 pin motherboard connector supports both 20-pin and 24-pin boards.

Sustained-load behaviour

The supply provides a steady 420W output for continuous operation rather than short bursts. Its fixed cable set includes one 15-inch SATA connector, one 14-inch ATX connector, one 14-inch 12V ATX connector, two 15-inch large peripheral connectors, two 6-inch large peripheral connectors and one 6-inch small peripheral connector. All leads are ready for immediate installation.

Thermals noise and power draw

An 80mm fan handles cooling while the unit draws either 110V or 220V from the wall depending on the switch position. The compact form factor weighs 0.1 kg and fits the original eMachines mounting points. No additional adapters are required for the listed motherboard and peripheral connections.

Questions about this item

How loud is the 80mm fan on this 420W unit when it runs all day?

The 80mm fan spins continuously to move heat out of the chassis; its speed adjusts to load so noise stays proportional to demand.

Which motherboard power plug must my board already have to use this RPSU-C99-66?

A 20-pin or 24-pin ATX socket is required; the 20+4 connector on the PSU fits both.

Will the 15-inch SATA lead reach drives in a legacy eMachines W3115 case?

Yes, the 15-inch SATA cable and 14-inch ATX cables are sized for those chassis layouts.
