Replacement ATX PSU for Legacy Systems

The Replace Power RPSU-C99-74 is an ATX power supply designed to replace faulty units in older desktop computers. It supports specific eMachines models including the D3123, D3315, D3415, H2341, H2482, and D6419. The unit also fits HP, Dell, Compaq, and other common brand systems requiring a standard ATX form factor. It provides a direct swap for aging hardware.

Sustained Load Protection Features

The power supply operates with switchable input voltage settings of 115 V or 230 V. It includes over current, over power, and over voltage protection circuits to safeguard components during continuous operation. A single 80 mm fan manages thermal output across extended sessions. These protections help maintain stable delivery when the system runs for long periods.

Compact Build and Connector Layout

The grey chassis features reduced depth dimensions of 5.9 inch height by 3.4 inch width for increased case compatibility. Weighing 2.5 units, it offers one SATA connector, one 20+4 pin ATX motherboard connector, one 12V ATX connector, two large power connectors, and one 6-inch small power connector. This assortment covers legacy and current peripheral needs.

Questions about this item

How loud or hot does the 80 mm fan get when the RPSU-C99-74 runs all day?

The unit uses a single 80 mm fan for cooling; noise and temperature will depend on the load placed on the supply.

Which cables or connectors must my system already have to use this power supply?

Your motherboard needs a 20-pin or 24-pin ATX socket and a 12 V ATX connector; drives require SATA or large Molex-style power plugs.

Will the 5.9-inch depth and 3.4-inch width fit the older eMachines D3123 chassis I want to keep?

The reduced-depth design at 5.9" x 3.4" matches the legacy eMachines models listed, so it should install without case modifications.
