Dell SFF TFX 320 W Replacement

This 320 W TFX power supply replaces Dell part numbers CN-0YX301 and CN-0XW605 in small-form-factor desktops. It delivers 320 W of continuous power through a 20+4 pin motherboard connector, a 4-pin CPU connector, two Molex, a floppy connector and two SATA connectors. An 80 mm double ball-bearing fan provides cooling. The unit accepts 100 to 240 V input.

Owners of compatible Dell SFF systems

It suits anyone restoring a Dell Inspiron 570S or 580S, or similar SFF models, that originally shipped with a 200 W, 250 W, 300 W or 350 W unit. Builders needing higher output for discrete graphics cards or workstation-class components should consider a higher-wattage design. Systems requiring a different form factor or proprietary pin-out are not supported.

Fixed 320 W output rating

The single specification that decides fit is the 320 W continuous rating. Verify that your system’s peak draw stays within this limit before installing. If the original PSU was rated above 350 W, this unit will not meet the power budget.

商品問答

How quiet is the 80 mm double-ball-bearing fan when the 320 W TFX supply runs continuously?

The 80 mm double-ball-bearing fan is designed for steady airflow; under constant 320 W load it spins faster and becomes audible, while lighter loads keep it quieter.

Which Dell slimline or SFF chassis already have the 20+4 pin, 4-pin CPU, two Molex, floppy and two SATA cables this unit provides?

It fits Dell SFF systems such as the Inspiron 570S and 580S that use part numbers CN-0YX301 or CN-0XW605 and accept a TFX-form-factor supply.

Will this 320 W TFX replacement work in an older Dell SFF that originally shipped with a 200 W or 250 W unit?

Yes — it replaces 200 W, 250 W, 300 W or 350 W supplies in compatible Dell SFF models and delivers up to 320 W continuous power.
