Replacement PSU for Acer Aspire

This new Replace Power RPSU-C99-81 unit serves as a direct 420W ATX replacement for Acer Aspire E360 E600 M1100 T180 T630 T670 F3 desktops. It is intended for owners restoring power to these specific systems or builders using compatible chassis. The grey power module arrives in new condition.

Connector layout and cooling

The supply includes one 15-inch SATA connector, one 14-inch 20+4 pin ATX connector, one 14-inch 12V ATX connector, two 15-inch large peripheral connectors, two 6-inch large peripheral connectors and one 6-inch small peripheral connector. An 80mm fan handles cooling while the input voltage selector covers 110V and 220V mains.

Upgrade from failed original unit

This unit replaces a faulty or degraded factory PSU in the listed Acer models, restoring reliable 420W delivery to the motherboard, drives and peripherals. The jump is worth it when the original supply has failed, shows instability or cannot support added components. It is not for builds needing higher wattage, modular cabling or modern GPU power connectors.

Questions about this item

Will the single 80 mm fan keep the 420 W unit cool during all-day use?

The 80 mm fan provides active cooling for sustained 420 W operation; noise and heat will depend on case airflow and load.

Does the switchable 110 V / 220 V input require any extra wiring or adapter?

The built-in voltage selector works with standard mains leads; no additional wiring or adapter is needed.

Which existing connectors must my Acer Aspire motherboard already have for this PSU to fit?

The board needs a 20/24-pin ATX socket, a 12 V ATX12V socket, SATA power ports and legacy peripheral/floppy sockets.
