Replacement PSU for HP Pavilion

The Replace Power unit serves as a direct replacement upgrade for the HP Pavilion 550-310 and 510-P020T desktop PCs. It fits the standard ATX form factor and arrives in a grey finish with a single cooling fan. The power supply is brand new and weighs one kilogram.

Connectors for a typical desktop build

The PSU provides a 20+4 pin ATX connector for the motherboard and a +12V 4-pin connector for the CPU. It also supplies three SATA connectors for drives and one 6-pin power connector for a graphics card. These cables cover the essential power needs of the supported HP chassis.

Upgrade path for the original HP unit

This unit replaces the factory power supply when it fails or when a build adds a discrete GPU that requires the 6-pin connector. The jump is worth it if the original PSU lacks that connector or shows instability under load. It is not for systems needing more than three SATA devices or additional PCIe power cables.
