Replace Power 220W Flex ATX power supply for HP Pavilion Slimline s5-1024lat

Proprietary 220W Flex ATX PSU

This proprietary Flex ATX unit delivers 220 W of continuous power for HP Pavilion Slimline s5-1024lat desktops and compatible slimline chassis. It replaces the original Bestec FH-ZD221MGR and HP 633195-001 parts with a direct-fit grey housing. Builders restoring or upgrading these specific small-form-factor systems will find the correct connector layout and voltage switching built in.

220 W ceiling for low-profile builds

The 220 W maximum output defines the practical limit for any graphics card or drive upgrades inside the host chassis. Input voltage auto-ranges between 115 V and 230 V, so the unit works worldwide without a manual switch. Only components that fit within this power envelope and the proprietary form factor can be supported; higher-wattage or standard ATX units will not mount or connect.

Direct-fit connectors and slim chassis mount

A 24-pin motherboard connector, a 4-pin CPU connector and two Sata power leads cover the typical Slimline peripheral set. The proprietary shell aligns with the original mounting points, so no adapter brackets or cable extensions are required. Grey finish matches the OEM aesthetic, and the 1 kg weight keeps stress on the chassis rails low during transport or vibration.
