Replacement PSU for HP Pavilion 550-103la

This Replace Power ATX unit is built as a direct replacement for the HP Pavilion Desktop 550-103la. It fits the original mounting points and cable routing of that specific chassis. The grey finish matches the stock aesthetic of the workstation.

Connector layout determines compatibility

The unit provides one 20+4 pin ATX connector, one +12V 4-pin CPU connector, one 6-pin power connector and three SATA connectors. A mini-SATA connector for a 5-inch device is also included. Verify that your motherboard and drives match this exact set before ordering.

Straightforward swap if cables reach

Installation follows the standard ATX procedure: remove the old unit, mount this one and connect the keyed plugs. The fixed cable lengths are designed for the 550-103la layout; builders using a different case may find the 4-pin CPU or 6-pin leads too short to route cleanly.
