TFX 320W replacement for HP Slimline

This TFX form-factor power supply is built to fit HP Pavilion Slimline s5371 and s5380 desktops. It delivers 320 W of continuous power through a 20+4 pin motherboard connector, a 4-pin CPU connector, two Molex, a floppy and two SATA leads. The unit accepts 100 to 240 V input and uses an 80 mm cooling fan.

320 W steady output with 420 W upgrade path

At 320 W the unit comfortably runs typical office and home PCs with integrated graphics, a single hard drive and a few USB peripherals. The supplier notes it can replace 200, 250, 300 or 350 W units and supports an upgrade to 420 W for builds that add a discrete graphics card or extra drives. Beyond that headroom the supply reaches its limit.

Fits Slimline and SFF chassis

The TFX size slides into narrow HP Slimline and other small-form-factor cases without modification. Its connector set covers legacy and current storage devices, freeing the builder from hunting adapters. The 80 mm fan handles airflow in tight enclosures, and the wide input voltage range lets the same unit work in different regions.

Questions about this item

Will this 320W TFX unit fit the same mounting points as the original 250W supply in my HP Pavilion Slimline s5371?

The TFX form factor matches the original slimline chassis, so it installs in the same mounting points used by the 250W or 300W unit you are replacing.

How can I confirm the 80mm cooling fan is spinning correctly after I power on the system?

Listen for the 80mm fan at the rear vent; you should hear it start immediately and feel steady airflow once the PC boots.

Which cables come attached and do I need any extra adapters for two SATA drives?

The unit includes a 20+4 pin motherboard connector, a 4-pin CPU connector, two Molex, a floppy lead and two SATA power plugs — enough for two SATA drives without extra adapters.
