Replacement PSU for Compaq Presario

This 420W ATX power supply replaces the original unit in Compaq Presario SR1522X, SR1820NX, SR2011WM, SR2018LA and SR2101LS desktops. It delivers standard ATX output through a grey enclosure with a single 80mm cooling fan. The input voltage selector switches between 110V and 220V mains.

Build quality and daily connectors

The unit weighs 0.1 and uses a 20+4 pin motherboard connector that fits both 20-pin and 24-pin sockets. One 12V ATX connector, one SATA connector, two large peripheral connectors on 15-inch leads, two more on 6-inch leads and a small floppy connector on a 6-inch lead cover internal devices. All cables are fixed.

Upgrade context and when it fits

This PSU replaces a failed or undersized factory supply in the listed Presario models. The jump is worth it when the original unit no longer holds voltage under load or when added drives exceed its connector count. It is not for builders who need modular cabling, higher wattage headroom or modern efficiency ratings.
