Compatible Slimline Replacement

This 220W Flex-ATX unit replaces the original Bestec FH-ZD221MGR in HP Pavilion Slimline desktops such as the s5-1246la and S5-1310T. It delivers 115 or 230 V input and fits the proprietary mounting used in these low-profile chassis. The grey enclosure matches the original aesthetic.

Connector Limitations

The supply provides a 24-pin motherboard connector, one 4-pin connector and two Sata power leads. No PCIe power connectors are present, so discrete graphics cards requiring auxiliary power cannot be used. Builders needing more than two Sata devices must add adapters or choose a different platform.

Proprietary Build Implications

The proprietary Flex-ATX form factor means the unit only fits Slimline cases designed for this exact shape. Standard ATX cases will not accept it. The fixed cable bundle includes the 24-pin, 4-pin and dual Sata leads; cable routing space is tight, so plan the installation order before securing the unit.

Questions about this item

Is the 220W Flex-ATX unit the correct replacement for my HP Pavilion Slimline s5-1246la?

Yes, this 220W Flex-ATX supply matches HP part 633195-001 and Bestec FH-ZD221MGR for the s5-1246la and S5-1310T models.

What does the 220W rating actually deliver inside a Slimline chassis?

The 220W maximum output runs the motherboard via a 24-pin connector, CPU via a 4-pin connector, and two Sata drives within the proprietary form factor.

Does the proprietary Flex-ATX design limit which motherboards or cases I can use?

The unit fits the specific HP Slimline mounting pattern and connector layout; it is not a standard Flex-ATX drop-in for other chassis.
