Genuine Dell 250W TFX12V power supply

This genuine Dell 250W TFX12V unit replaces the original supply in select Inspiron, Vostro and Studio slimline desktops. It delivers 250 watts through a single 24-pin ATX connector, a 4-pin ATX connector, three SATA power connectors and one floppy connector. The grey chassis houses one fan for cooling.

TFX12V form factor with standard ATX and SATA

The TFX12V layout fits the narrow bays used by the listed Dell SFF systems without modification. One 24-pin and one 4-pin ATX connector power the motherboard, while three SATA connectors serve drives and the floppy connector supports legacy devices. A single fan manages airflow in the compact enclosure.

250-watt limit defines upgrade scope

The 250W rating restricts the total power available for CPU, graphics and drives, so high-draw components cannot be supported. Builders needing more headroom for discrete GPUs or additional drives must look beyond this form factor. The fixed cable set also limits the number of SATA devices to three.
