Proprietary 220W Flex-ATX PSU

This Replace Power unit is a proprietary Flex-ATX power supply rated at 220W. It is built as a direct replacement for the Bestec FH-ZD221MGR used in HP Pavilion Slimline desktops such as the S5-1554 and s5-1024 models.

Verify Slimline Chassis and Connector Needs

Before ordering, confirm that your Slimline chassis accepts a proprietary Flex-ATX form factor. Check that the motherboard requires a 24-pin main connector plus a 4-pin auxiliary connector and that two Sata power leads are sufficient for your drives.

Low-Profile Thermals and 115/230V Input

The compact design fits the restricted airflow of Slimline cases while delivering 220W continuous power. It operates on 115V or 230V mains input without a voltage selector switch. Acoustic output will follow the original Bestec FH-ZD221MGR profile for this chassis class.
