  • TypeAT
  • 400W output powers demanding components

TFX 400 W replacement PSU

This TFX form-factor unit delivers 400 W of continuous power and replaces the FSP FSP250-50SAV in slimline and small-form-factor desktops. It upgrades systems that originally shipped with 200, 250, 300 or 350 W supplies. Builders fitting a compact chassis will find a direct mechanical and electrical match. It is not for buyers who need higher wattage or a standard ATX footprint.

20+4 pin motherboard and 4-pin CPU connectors

The unit provides a 20+4 pin motherboard connector, a 4-pin CPU connector, two Molex, a floppy connector and two SATA power leads. An 80 mm double-ball-bearing fan handles cooling inside the slim enclosure. Input voltage spans 100 to 240 V for worldwide use. Builders requiring additional PCIe power cables or modular cabling will need a different supply.

Dell desktop compatibility

The replacement targets a wide range of Dell desktops that use the TFX form factor, simplifying the swap without adapter cables. The included connector set covers legacy and current drives in one package. Users whose systems demand more than two SATA devices or lack a floppy header gain no extra connectors from this unit.
