420 W TFX Slimline Replacement

This 420 watt TFX power supply replaces Delta DPS-220AB-2 DCSLF PS-5251-5 units in slimline and small-form-factor desktops. It fits systems originally shipped with 200, 250, 300 or 350 watt PSUs and uses an AT form factor. The unit is new and built as a direct drop-in replacement.

Capacity and headroom

The 420 watt output provides headroom above 250, 300 and 320 watt factory units, supporting additional drives or a modest graphics card. It will run out when sustained loads exceed 420 watts or when peak transient demands surpass the unit's protection limits. The 80 mm double ball-bearing fan handles cooling for typical SFF workloads.

Connectors and input limits

Included cables are a 20+4 pin motherboard connector, a 4-pin CPU connector, two Molex, one floppy and two SATA. Input voltage range is 100 to 240 volts, so the PSU works worldwide without a switch. No PCIe power connectors are present, limiting discrete GPU options to slot-powered cards only.
