Direct replacement for legacy eMachines systems

This ATX power supply is built to replace the original units in eMachines T2882, T2885, T2890, T2891, T2892 and T2893 desktops. It delivers the standard connectors those boards expect, including a 20+4 pin motherboard plug, a 12V ATX connector, one SATA connector, two large peripheral connectors and two small peripheral connectors. The 115 / 230 V switchable input lets it work on mains worldwide.

Compact grey chassis with single 80 mm fan

The grey steel housing measures 5.9 inches deep by 3.4 inches wide, a reduced depth that fits tight legacy cases without blocking drive bays or cables. A single 80 mm fan handles cooling, while over-current, over-power and over-voltage protection circuits guard connected components. Weighing 2.5 kg, it feels solid for a budget replacement unit.

Upgrade path for failed or noisy OEM units

This unit replaces a failed or ageing factory supply in the listed eMachines models and similar vintage ATX systems that use the same connector mix. The jump is worth it when the original PSU has died, runs loud or cannot spin up reliably. Builders needing multiple SATA drives, PCIe graphics power or higher total wattage should look elsewhere.

Questions about this item

Does the 20+4 pin ATX connector limit power delivery to older motherboards?

The 20+4 pin ATX connector fits both 20-pin and 24-pin motherboard sockets, so it works with the legacy eMachines models listed and newer boards alike.

Will the reduced depth of 5.9 inches height by 3.4 inches width fit my eMachines T2882 case?

Yes, the shorter 5.9-inch height and 3.4-inch width are designed for the compact chassis used by the T2882, T2885, T2890, T2891, T2892 and T2893.

How do I set the 115 / 230 V input switch before installing the unit?

Slide the red voltage selector to 115 V for North America or 230 V for Europe before plugging in; forgetting this step can damage the supply.
