Replacement PSU for Compaq Presario

This Replace Power unit delivers 420W through a standard ATX form factor. It targets owners of Compaq Presario SR2163WM, SR2168HM, SR2170NX, SR2177CL and SR2180NX desktops who need a direct swap for a failed original supply. The grey enclosure houses a single 80mm fan for cooling.

Check connectors and voltage switch

Verify that your motherboard accepts the 20+4 pin ATX plug and the 12V ATX connector supplied. Confirm the 110V/220V selector matches your mains supply before installation. Ensure the four large peripheral plugs and the single SATA lead cover the drives you intend to power.

Suits legacy desktop repairs

Ideal for technicians restoring the listed Presario models or similar vintage HP and Dell systems that use identical pinouts. Builders assembling modern platforms or requiring multiple SATA devices, PCIe graphics power or higher wattage should look at alternative units.
