HP TFX 300W Replacement

This 300 watt TFX power supply replaces the HP 447402-001 and 447585-001 units in slimline and small-form-factor desktops. It fits the same mounting points and connector layout as the original equipment. Builders upgrading legacy office PCs or repairing a failed unit will find it a direct mechanical and electrical match.

300W continuous output

The unit delivers 300 watts steady power through a 20+4 pin motherboard connector, a 4-pin CPU connector, three Molex, one floppy and three SATA leads. It handles typical office workloads and modest graphics cards, but systems requiring more than 300 watts or additional PCIe power connectors will exceed its capacity.

TFX form factor

The physical TFX chassis and connector set decide compatibility; only cases and motherboards designed for TFX supplies with this exact pin-out will accept it. Buyers needing ATX dimensions, higher wattage or dedicated GPU power cables must choose a different form factor.

Questions sur cet article

Will this 300 W TFX supply fit the same HP 447402-001 chassis that currently runs a 250 W unit?

Yes, it replaces 200, 250, 300 or 350 W TFX power supplies in compatible HP Slimline and SFF models.

How can I confirm the 80 mm double ball-bearing fan is spinning correctly after installation?

Listen for the fan at the rear vent; the unit powers on when the 20+4 pin motherboard and 4-pin CPU connectors are seated.

Which cables come attached and what extra connectors might I need for additional drives?

The PSU includes 20+4 pin motherboard, 4-pin CPU, three Molex, one floppy and three SATA leads; extra Molex or SATA cables must be sourced separately.
