TFX 320 W Replacement PSU

This TFX form-factor power supply delivers 320 W for HP Pavilion Slimline s5310f s5320es s5330es systems. It fits the slimline chassis and provides a direct upgrade over the original 200 W, 250 W, 300 W or 350 W units.

TFX Form-Factor Limits

The TFX shape restricts this unit to slimline and small-form-factor cases that accept the same mounting pattern. Standard ATX cases cannot accommodate the shorter depth and different screw positions.

320 Watt Output Decides Fit

The 320 W continuous rating determines whether the PSU can support your CPU, graphics card and drive count. Builds needing more headroom should consider the 420 W upgrade path instead.

Questions about this item

Should I choose the 320 W or the 420 W upgrade for my HP Pavilion Slimline?

The unit supplied is a 320 W TFX power supply; the 420 W figure is mentioned only as a possible upgrade path for systems that originally shipped with 200, 250, 300 or 350 W units.

What does the 320 W rating deliver in a real HP Pavilion Slimline s5310f?

It provides 320 W of steady power through a 20+4 pin motherboard connector, a 4-pin CPU connector, two Molex, a floppy connector and two SATA connectors, cooled by an 80 mm fan.

Does the TFX form factor and 20+4 pin connector limit what I can install?

The supply uses the TFX form factor with a standard 20+4 pin ATX motherboard connector, a 4-pin CPU connector, two Molex, a floppy connector and two SATA connectors, so it fits the listed Slimline models directly.
