Direct replacement for HP Slimline s5-1118

This 220 W Flex-ATX unit is built to fit the proprietary chassis of the HP Pavilion Slimline s5-1118 desktop. It delivers the exact connector layout the original Bestec FH-ZD221MGR provided, including a 24 pin motherboard plug, a 4 pin auxiliary connector and two Sata power leads. The grey enclosure matches the OEM aesthetic.

Upgrade from a failed or noisy OEM supply

When the factory Bestec unit fails or develops coil whine, this Replace Power model restores reliable operation without modifying the case. The jump is worth it when the original 220 W brick can no longer hold stable voltages under load. It accepts 115 or 230 V input so it works in any region the original system supported.

220 W headroom for Slimline builds

The 220 W rating comfortably handles the integrated graphics, low profile CPU and a pair of Sata drives typical of these Slimline systems. It runs out when a discrete graphics card or additional drives are added beyond the two Sata connectors provided. Builders needing more power or extra connectors must look elsewhere.

Questions about this item

Will the 24-pin motherboard connector and 4-pin connector fit the HP Pavilion Slimline s5-1118?

Yes, this 220 W Flex-ATX unit supplies a 24-pin motherboard connector and a 4-pin connector that match the original HP 633195-001 pinout.

Which screw holes line up when I swap the old Bestec FH-ZD221MGR for this replacement?

The Flex-ATX chassis uses the standard low-profile mounting pattern, so the four rear screws on your Slimline s5-1118 will align without modification.

Do the two Sata power plugs run directly from the PSU or need an adapter later?

Two Sata connectors are native on the cable harness; no adapter is required for Sata drives.
