Replacement 550W ATX Power Supply

This Replace Power unit is a direct swap for HP Pavilion 550-169c and 550-175hk desktops. It delivers 550W through a standard ATX form factor in a grey enclosure. The package includes a 20+4 pin ATX connector, a +12V 4-pin connector, one 6-pin power connector and three SATA connectors for drives.

Sustained load behaviour

A single fan cools the supply during continuous operation. The connector set supports a motherboard, CPU power and multiple SATA devices simultaneously. The unit is built as a replacement upgrade, meaning it matches the original electrical specification for long-term service in the target chassis.

Upgrade context

This supply replaces the factory unit in the listed Pavilion models when the original fails or when a rebuild requires a fresh PSU. It is not for builders who need more connectors than the provided 20+4 pin, 4-pin, 6-pin and three SATA leads. It is not for systems that require a different form factor or higher wattage than 550W.

Questions sur cet article

How loud does the single fan get when the 550 W unit runs continuously under load?

The power supply uses one fan to move air through the chassis; acoustic output will depend on case airflow and ambient temperature rather than a published sound-pressure figure.

Which existing cables or connectors must my motherboard and drives already provide for this PSU to work?

Your board needs a 20+4 pin ATX socket and a +12 V 4-pin CPU socket, while storage devices require standard SATA power plugs.

Will the 6-pin and SATA leads power older graphics cards and mechanical drives I want to keep?

Yes, the single 6-pin PCIe connector and three SATA power connectors can supply legacy GPUs and hard drives that use those interfaces.
