Replacement for HP Slimline s5-1128p
This 220W Flex-ATX unit replaces the original Bestec FH-ZD221MGR in HP Pavilion Slimline s5-1128p desktops. It delivers the proprietary form factor and connector layout required by these low-profile chassis. Builders restoring or repairing these specific systems will find a direct mechanical and electrical match.
Proprietary Flex-ATX constraints
The supply uses a non-standard Flex-ATX shape and a fixed cable harness, so it fits only compatible Slimline cases. Its 24-pin motherboard connector, 4-pin auxiliary connector and two Sata power leads cover the factory board and drives. Systems needing additional PCIe power or more than two Sata devices cannot be supported.
220W capacity and headroom
Rated at 220W across 115V and 230V input, the unit handles the original CPU, integrated graphics and a pair of Sata drives. Adding a discrete graphics card or extra storage will exceed the available power. The design targets the factory configuration; upgrades beyond that scope require a different platform.

Questions about this item
Is the 220 W rating enough for my Slimline build?
The unit delivers up to 220 W total output, matching the original Bestec FH-ZD221MGR specification for HP Pavilion Slimline s5-1128p systems.
What does the 24-pin motherboard connector actually power?
It supplies the main board power rail for the Slimline chassis, exactly as the original HP 633195-001 design requires.
Does the Flex-ATX form factor limit the Sata connectors to two drives?
The supply includes two Sata power leads, so only two Sata devices can be powered directly from this 220 W unit.
