Replace Power power supply for HP Pavilion 550-108a 550-110a DT PC

Direct replacement for HP Pavilion 550 desktops

This Replace Power unit is a new ATX power supply built to fit the HP Pavilion 550-108a and 550-110a DT PCs. It delivers standard ATX power through a grey chassis with a single cooling fan. The unit serves as a direct swap for the original factory supply in those specific models.

Verify connector needs and case fit before ordering

Check that your motherboard uses a 20+4 pin ATX main connector and a +12V 4-pin CPU connector. The PSU provides one 6-pin power connector, two standard SATA connectors and one mini-SATA connector for 5-inch drives. Ensure the physical dimensions match the Pavilion 550 chassis and that the single fan orientation suits the case airflow.

Upgrades a failed or capacity-limited original

This unit replaces the original power supply when it has failed or when the system needs the provided connector set for added drives or a graphics card requiring a 6-pin feed. The jump is worth it if the old unit cannot power the installed components or if its fan has become noisy. It is not for builders needing higher wattage, modular cables or multiple 6-pin or 8-pin GPU connectors.
