Dell SFF replacement PSU

This 350 watt TFX power supply is built to fit Dell SFF systems carrying part numbers CN-0YX301 and CN-0XW605. It serves owners of slimline desktops who need a direct replacement for a failed or ageing unit.

350 watt capacity and headroom

The unit delivers 350 watts of continuous power and can replace original 200, 250, 300 or 350 watt supplies. It handles typical office peripherals and expansion cards, but systems requiring sustained loads above 350 watts will exceed its rating.

Bundled connectors and cooling

Included cables provide a 20+4 pin motherboard connector, a 4 pin CPU connector, two Molex, one floppy and two SATA power leads. An 80 mm double ball bearing fan supplies active cooling across the 100 to 240 volt input range.

Questions about this item

Will this 350W TFX unit fit the same mounting points and cable reach as the original Dell SFFCN-0YX301 CN-0XW605 300W supply?

The unit is built to TFX dimensions and carries the same 20+4 pin motherboard, 4-pin CPU, two Molex, floppy and two SATA connectors, so it matches the Dell SFFCN-0YX301 CN-0XW605 mounting and cable layout.

How can I verify the 80mm double-ball-bearing fan is spinning correctly once the PSU is installed?

After power-on, listen for the 80mm fan at the rear vent; the double-ball-bearing design runs quietly at idle and increases speed under load, confirming normal operation.

Which cables come attached and what extra connectors would I need to buy separately?

The PSU includes fixed 20+4 pin motherboard, 4-pin CPU, two Molex, one floppy and two SATA leads; no additional cables are required for a typical Dell SFF build.
