Replacement PSU for eMachines T3062 T3065 T3085

This 420W ATX power supply is a direct replacement for the listed eMachines desktops. It delivers the standard connectors those systems expect, including a 20+4 pin motherboard plug, a 12V ATX connector, SATA, Molex and a floppy power lead. The unit fits a standard ATX mounting pattern and uses a single 80mm fan for cooling.

Suits owners restoring the named eMachines models

Builders who need more than 420W of continuous power should look elsewhere. Systems that require PCIe power connectors for a discrete graphics card cannot use this unit. Anyone wanting modular cabling or an 80 Plus efficiency badge will not find those features here.

420W continuous output

The single rail design provides 420W total power across the 20+4 pin main connector and the dedicated 12V ATX lead. Input voltage is selectable between 110V and 220V. Cable lengths are 14 inches for the main ATX and 12V leads, and 15 inches for the SATA connector.

Questions about this item

How loud and hot does the RPSU-C99-52 get when running continuously?

The unit uses a single 80 mm fan and a switchable 110V/220V input to deliver 420W, so thermal output scales with load; typical office workloads keep the fan at low speed while heavier draws spin it faster.

Which cables must my system already provide for the RPSU-C99-52 to connect?

The PSU supplies one 15-inch SATA lead, one 14-inch 20+4 pin motherboard lead, one 14-inch 12V ATX lead, two 15-inch and two 6-inch large peripheral leads, plus one 6-inch small peripheral lead — no extra cables are required.

Will the RPSU-C99-52 fit and power an older eMachines T3062 or T3092 chassis?

Yes — the model is listed as a direct 420W replacement for eMachines T3062, T3065, T3085, T3042, T3090 and T3092, matching their ATX form factor and connector layout.
