Dell Inspiron 570S 580S TFX replacement

This 320 W TFX power supply is built specifically for the Dell Inspiron 570S and 580S small-form-factor desktops. It replaces the original 200 W, 250 W, 300 W or 350 W units and fits the slimline chassis without modification. The AT-type design delivers 320 W of continuous power for everyday computing and peripheral upgrades. It suits owners restoring or upgrading these exact models.

20+4-pin, 4-pin CPU, SATA and Molex connectors

The loom provides a 20+4 pin motherboard connector, a dedicated 4-pin CPU plug, two SATA power leads, two Molex plugs and a floppy connector. This mix covers the motherboard, processor, legacy drives and modern SATA storage in one harness. TFX mounting holes align with the Dell chassis so installation uses the original screws. No adapter cables are required for the supported configurations.

80 mm fan cooled at 100–240 V input

An 80 mm cooling fan draws air through the unit while operating from 100 V to 240 V mains. The fan runs at a steady speed under typical office loads, keeping internal temperatures stable without audible ramping. At 320 W output the supply stays within its thermal envelope for normal desktop workloads. It draws only the power the system demands across the full input range.

Questions about this item

Does the 20+4 pin motherboard connector follow the AT standard used by the Dell Inspiron 570S and 580S?

Yes, the unit is specified as AT type and the 20+4 pin connector matches the motherboard power interface on those models.

Will this TFX form-factor supply fit the slimline chassis of the Inspiron 570S and 580S?

The supply is built to the TFX standard and is listed as compatible with the slimline and SFF chassis of the 570S and 580S.

How do I install the replacement and what step is often missed?

Disconnect the old unit, fit the TFX supply in the same bay, then attach the 20+4 pin motherboard, 4-pin CPU, two Molex, floppy and two SATA cables; the step often missed is seating the 4-pin CPU connector firmly.
