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.

Questions about this item

Which cables come attached to this power supply and what extra connectors might I need to buy?

The unit includes a 20+4 pin ATX connector, a +12V 4-pin power connector, one 6-pin power connector, three SATA connectors and one mini-SATA connector for 5-inch drives. No other cables are mentioned.

How do I decide between the 550-108a and 550-110a versions listed in the title?

Both model numbers refer to the same replacement power supply; the title simply lists the two compatible HP Pavilion desktop models. Choose the one that matches your PC's model sticker.

What does the single fan and grey ATX form factor mean for cooling and fit inside my HP Pavilion 550?

One built-in fan provides active cooling while the standard ATX dimensions and grey colour match the original chassis, so the unit fits the 550-108a and 550-110a cases without modification.
