Dell SFF compatibility

This 320W TFX power supply replaces Dell W208D W209D W210D TFX025D5WB units in slimline and small-form-factor desktops. It delivers steady power for older PCs and new custom builds that use the TFX form factor. The unit accepts 100/240 V input for worldwide use.

Build integration

A 20+4 pin motherboard connector, 4-pin CPU connector, two Molex, one floppy and two SATA connectors cover the essential internal devices. The TFX chassis fits the original mounting points so no case modification is required. An 80mm double ball bearing fan provides active cooling without relying on passive airflow alone.

Sustained-load behaviour

Rated at 320W continuous output, the supply is designed to maintain its rated wattage rather than peak briefly. The double ball bearing fan is built for long-term operation under constant load. It does not suit systems that need more than 320W or connectors beyond those listed.
