Compatible HP Pavilion 550 power supply

This Replace Power ATX unit is built as a direct replacement for HP Pavilion 550-102a and 550-103a desktop PCs. It delivers standard ATX power in a grey chassis with a single cooling fan. The unit suits owners of those specific models who need a new power supply to restore or maintain operation.

Simple connector swap installation

Installation consists of unplugging the old unit and connecting the provided cables: one 20+4 pin ATX connector, one +12V 4-pin connector, one 6-pin connector, one mini-SATA connector and two standard SATA connectors. The fixed cable set means you cannot remove unused leads, so cable routing space inside the Pavilion chassis may be tight.

Verify your exact Pavilion model first

Before ordering, confirm the computer is a Pavilion 550-102a or 550-103a desktop; other 550 variants or different HP lines may use a different power supply pinout or form factor. This unit is not for builders who need modular cables, higher wattage for discrete graphics upgrades, or a supply that fits a standard ATX case outside the Pavilion 550 series.
