Replacement PSU for HP Slimline s5-1200z

This 220W Flex-ATX power supply replaces the original Bestec FH-ZD221MGR unit in HP Pavilion Slimline s5-1200z desktops. It delivers 115 / 230 V input compatibility and a grey proprietary form factor. The unit weighs 1 and fits many Slimline systems using the same chassis layout.

Direct swap for Bestec FH-ZD221MGR

The supply matches the HP 633195-001 and DPS-220AB-6 part numbers for a direct upgrade. It provides a 24 pin motherboard connector, a 4 pin connector and 2x Sata connectors for peripheral power. The jump is worth it when the original unit fails or shows instability under load.

220W headroom for Slimline builds

The 220W maximum output comfortably handles the motherboard, CPU and a pair of Sata drives in the Slimline chassis. It runs out when discrete graphics cards or additional high-draw peripherals are added beyond the provided connectors. Builders who need more power or extra connectors must choose a different platform.

Questions about this item

What form factor and wattage does the Flex-ATX power supply use for the HP Pavilion Slimline s5-1200z?

It is a Flex-ATX unit rated at 220 W, matching the original Bestec FH-ZD221MGR and HP part 633195-001 used in many Slimline systems.

Which power connectors must be attached during installation, and which one is most often missed?

Connect the 24-pin motherboard plug, the 4-pin CPU plug and both Sata power leads; the 4-pin CPU connector is the one most frequently overlooked.

When should the internal cooling fan be cleaned or the unit replaced to maintain reliable power delivery?

Clean the fan intake every 6–12 months; if the PSU reaches 220 W load continuously or shows voltage drift, plan a replacement.
