HP Slimline compatible Flex-ATX supply

This Replace Power 220W Flex-ATX unit is built for the HP Pavilion Slimline s5-1205z desktop. It matches the original Bestec FH-ZD221MGR form factor and delivers 220W maximum power output. The grey proprietary chassis fits the low-profile case dimensions required by these systems.

Buyers needing a direct swap for the OEM power supply in a compatible Slimline desktop will find the correct connector layout here. Builders wanting higher wattage for discrete graphics upgrades or standard ATX mounting should look at other form factors because this is a proprietary low-profile design.

220W maximum power output

The 220W rating determines whether this unit can support your installed components. It provides a 24-pin motherboard connector, a 4-pin connector and two Sata connectors for peripherals. Input voltage ranges from 115 to 230 V for worldwide mains compatibility.

Questions about this item

How do I install the Replace Power 220W Flex-ATX into my HP Pavilion Slimline s5-1205z and what step is often missed?

Remove the side panel, unscrew the old unit, slide this Flex-ATX supply into the proprietary bay, secure it with the same screws, then connect the 24-pin motherboard plug, the 4-pin CPU plug and the two Sata power leads. The step most people miss is seating the 4-pin CPU connector fully — it clicks only when pushed straight in.

What maintenance or replacement will this power supply need later?

The internal fan is the only moving part; clean dust from its intake vents every 6–12 months with compressed air. If the fan becomes noisy or the unit shuts down under load, replace the entire 220W supply — no user-serviceable capacitors or fuses are inside.

What limit appears first when the Replace Power 220W runs at full load for a long time?

The 220W maximum output is the hard ceiling; sustained draws at or near that level trigger over-current protection and shut the unit down. Heat buildup in the slim chassis reinforces the limit, so keep total system draw comfortably below the rated maximum.
