Direct replacement for eMachines desktops

This Replace Power RPSU-C99-62 unit is a 420W ATX power supply built to fit eMachines W3052 W3400 W3410 W3502 W3503 W3506 systems. It delivers the standard connectors those chassis expect, including a 20+4 pin motherboard plug, a 12V ATX lead, SATA, Molex and floppy power cables. The grey enclosure uses a single fan for cooling.

Swaps out the original 420W unit

When the factory supply fails or becomes unstable, this module restores the same 420W rating without rewiring the case. The 20+4 pin connector works with both 20-pin and 24-pin boards, while the included 15-inch SATA lead and 14-inch ATX leads reach the stock drive and motherboard positions. The upgrade is worth it when the original unit shows voltage drift, fan noise or no power at all.

Suits owners of the listed eMachines models

Builders repairing a W3052 W3400 W3410 W3502 W3503 or W3506 will find the connector mix matches the original layout. Users needing higher wattage for discrete graphics cards, additional drive bays or modern CPU power phases should look elsewhere, as this unit provides only the baseline 420W and the legacy connector set.

Questions about this item

Will the RPSU-C99-62 fit inside an eMachines W3052 case?

Yes, the unit is a standard ATX form factor and is listed as a direct replacement for the eMachines W3052 W3400 W3410 W3502 W3503 W3506 chassis.

How do I connect the 20+4 pin ATX connector to a 24-pin motherboard socket?

The 14-inch 20+4 pin cable splits into a 20-pin block and a 4-pin block; join them together before inserting into the 24-pin motherboard socket so all pins seat fully.

When should I replace the internal fan in this 420W power supply?

Replace the single fan if it becomes noisy, spins slowly or stops, as the unit relies on that one fan for all internal cooling.
