420W ATX Replacement Power Supply

The Replace Power RPSU-C99-50 is a 420W ATX power supply designed to replace a failed unit in eMachines T3410, T3414, T3418, T3408, T3422 and T3504 desktops. It also fits HP, Dell, Compaq and other common systems requiring standard ATX power. A single 80mm fan provides cooling.

Upgrade From Failed OEM Unit

This unit replaces an original power supply that has failed or become unstable in the listed eMachines models and compatible OEM systems. The jump is worth it when the existing PSU no longer delivers reliable power or has damaged connectors. It restores operation with a new 420W module and a full complement of cables.

Limits Of Fixed 110V/220V Switch

The supply uses a manual 110V/220V input voltage switch rather than active PFC. Users must set the switch correctly for the local mains voltage before connecting power. The 20+4 pin ATX connector supports both 20-pin and 24-pin motherboards, while SATA and peripheral connectors cover standard drives. Builders needing higher wattage or modular cables cannot use this unit.
