Direct replacement for legacy eMachines systems

This unit replaces the original power supply in eMachines T2796 T2824 T2825 T2792 T2858 T2842 desktops. It fits the reduced depth chassis of those models without modification. Builders restoring or maintaining these specific systems will find the connector layout matches the factory configuration.

Steady output under continuous load

Over current and over power protection circuits monitor the rails during extended operation. The single 80 mm fan maintains airflow across the internal components while the supply delivers rated power. High efficiency design reduces wasted heat so the unit runs cooler during long work sessions.

Compact ATX form factor with essential connectors

Grey steel housing measures 5.9 inches height by 3.4 inches width for tight legacy cases. One SATA connector serves a modern drive while two large peripheral connectors and one six inch small connector support older devices. The 20+4 pin ATX and dedicated 12V ATX plugs cover motherboard requirements. Input voltage selector switches between 115 V and 230 V for worldwide use.
