Gateway desktop replacement

This 420 W ATX unit from Replace Power is built as a direct swap for Gateway 102015, 102544, 500GR, 503GR, 504GR, 506GR, 508GE and 550GR desktops. It also fits HP, Dell, Compaq and other common systems that use standard ATX mounting. The grey chassis weighs 0.1 kg and includes a single cooling fan.

Single-fan ATX build quality

A switchable 110 V / 220 V input lets the supply work on either mains voltage. Cooling is handled by an 80 mm fan. Cabling provides one 15-inch SATA connector, one 14-inch ATX connector that supports both 20-pin and 24-pin motherboard headers, and one 14-inch 12 V ATX connector. The standard ATX form factor means it drops into existing screw holes without modification.

Upgrade from a failed original

The unit replaces a faulty or under-powered factory PSU in the listed Gateway models and compatible OEM desktops. The jump is worth it when the original supply has failed, when a newer graphics card or additional drives demand more than the old unit could deliver, or when a noisy fan signals end of life.

Questions about this item

Does the 420W ATX unit use a 110V or 220V input switch?

The RPSU-C99-73 has a manual 110V/220V selector switch on the rear. Set it to match your local mains voltage before plugging the unit in.

What ATX power connector lengths and pin counts does the RPSU-C99-73 provide?

It ships with a 14-inch ATX cable that fits both 20-pin and 24-pin motherboard headers.

Which cable should be connected first when installing this power supply?

Seat the 20/24-pin ATX connector firmly into the motherboard before attaching the 12V and SATA leads; skipping this step leaves the board unpowered.
