Compatible HP Pavilion 550 PSU

This Replace Power unit is a new ATX power supply built for HP Pavilion 550-132 and 550-159c desktop PCs. It delivers standard ATX power through a grey chassis with a single cooling fan. The unit weighs one kilogram and serves as a direct replacement or upgrade for the original factory supply.

Connector layout and upgrade fit

It provides one 20+4 pin ATX connector, one +12V 4-pin power connector, one 6-pin power connector and three SATA connectors. A mini-SATA connector for 5 inch drives is also included. This fits systems needing those exact connections without adapter cables.

Check motherboard power headers

Verify that your motherboard accepts a 20+4 pin main power plug and a 4-pin +12V CPU plug. Confirm the case can hold a standard ATX unit and that the SATA count matches your drive complement. Ensure the 6-pin connector satisfies any dedicated graphics card you plan to keep.

Questions about this item

Will the ATX form factor and 20+4 pin connector fit the HP Pavilion 550-132 chassis and motherboard?

This PSU uses the standard ATX form factor and includes a 20+4 pin ATX connector that matches the motherboard on the 550-132 and 550-159c models.

Which cables must be connected during installation to avoid a no-post condition?

Connect the 20+4 pin ATX cable and the +12V 4-pin CPU cable first; the system will not start if the 4-pin CPU power is missed.

How many SATA drives can be powered later if I add storage?

The unit provides three SATA power connectors, so up to three SATA drives can be powered simultaneously.
