Dell XW604 XW605 TFX Replacement PSU

This 420 watt TFX power supply replaces the original 250 watt, 300 watt or 320 watt units in Dell XW604 and XW605 small-form-factor desktops. It fits the same slimline chassis and uses the existing mounting points. The unit accepts 100 to 240 volt input for worldwide use.

TFX form-factor limits upgrade options

The TFX shape is shorter than standard ATX units, so it only fits cases designed for this size. The 420 watt output supports typical office components and modest graphics cards, but high-power GPUs or many drives may exceed the available headroom. Cable lengths are set for compact Dell layouts.

420 watt rating decides suitability

The 420 watt maximum determines whether the PSU can handle your planned components. If the combined load of the CPU, graphics card and drives stays below this figure, the supply will deliver stable power. Builds needing more headroom require a different chassis and PSU format.

商品問答

Should I choose the 420 W unit if my Dell XW604 currently runs a 300 W power supply?

Yes — the 420 W model replaces 200 W, 250 W, 300 W and 350 W units in the XW604 and XW605, giving extra headroom for upgrades.

What does the 420 W rating actually deliver inside a Dell XW604?

It supplies up to 420 W total across the 20+4 pin motherboard, 4-pin CPU, two Molex, floppy and two SATA connectors.

Does the TFX form factor with 20+4 pin and 4-pin CPU connectors fit the Dell XW605 motherboard?

The unit is built to TFX dimensions for slimline and SFF chassis and includes the 20+4 pin motherboard and 4-pin CPU connectors required by the XW605.
