420W ATX PSU for Compaq Presario

This 420W ATX power supply from Replace Power is built as a direct replacement for specific Compaq Presario models including SR2264WM, SR5030NX, SR5034X and SR5160KL. It delivers standard ATX power in a grey chassis with a single cooling fan. The unit suits owners restoring or repairing these legacy desktops who need a compatible power module without modification.

Installation uses fixed cable lengths

The supply ships with a 14-inch ATX connector supporting both 20-pin and 24-pin motherboard headers, a 14-inch 12V ATX connector, one 15-inch SATA connector, two 15-inch large power connectors, two 6-inch large power connectors and one 6-inch small power connector. Short 6-inch leads may not reach drives in taller chassis, so cable routing should be planned before mounting the unit.

Verify Compaq model and connector needs

Confirm the exact Presario model number matches the supported list before ordering. Check that the motherboard requires a 20-pin or 24-pin ATX main connector and a 12V ATX auxiliary connector. Ensure the single SATA power lead and the mix of large and small peripheral connectors match the drive and device count in the system.
