Compatible HP Slimline Models

This 300W TFX power supply is built for HP s5114f, s5113w and s5112f desktop computers. It replaces the original lower-wattage unit to support additional internal devices. The AT-type form factor fits the Slimline chassis directly. Owners of other HP or Dell systems should verify dimensions and connector layout before purchasing.

Sustained 300 Watt Output

The unit delivers a continuous 300W across its rails rather than a short peak rating. An 80mm double ball-bearing fan maintains airflow under prolonged load. Input voltage auto-switches between 100V and 240V for stable operation worldwide. Builders adding multiple drives or expansion cards gain headroom without thermal throttling.

Connector Layout and Cooling

A 20+4-pin main connector, one 12V 4-pin CPU plug, three Molex, three SATA and one floppy connector cover legacy and current peripherals. The TFX casing and rear mounting points align with the Slimline bracket screws. The 80mm fan exhausts heat through the standard rear grille, keeping cable routing simple inside the narrow case.

Questions about this item

How loud and hot does the 80 mm double ball-bearing fan get when the 300 W supply runs all day?

The 80 mm fan uses double ball bearings for quieter, longer-life cooling under continuous 300 W loads.

Which existing cables and motherboard headers must my HP s5114f already have for this TFX unit to connect?

Your board needs a 20+4 pin main socket, a 4-pin 12 V CPU header, plus Molex, SATA and floppy drives for the peripherals.

Will the 100/240 V input and 20+4 pin main connector work with the original HP s5112f wiring without adapters?

Yes, the 100/240 V auto-range input and native 20+4 pin connector match the s5112f factory wiring exactly.
