Dell Delta DPS-250AB-28 B Replacement

This 275W TFX power supply replaces the Dell Delta DPS-250AB-28 B unit in slimline and small form factor desktops. It supports systems originally equipped with 200, 250, 300 or 350 watt power supplies. The upgrade delivers 275 watts of steady power for older PCs and custom builds with a range of peripherals.

TFX Form Factor With 80mm Double Ball Bearing Fan

The compact TFX chassis fits narrow Dell cases while the 80mm cooling fan uses double ball bearings for durable airflow. Connectors include a 20+4 pin motherboard plug, a 4-pin CPU connector, three Molex, one floppy and three SATA leads for drives and legacy devices. Input voltage ranges from 100 to 240 volts for worldwide use.

275 Watt Output Rating

The single specification that determines fit is the 275 watt output; it must meet or exceed the power draw of your installed components. Buyers whose builds require more than 275 watts should not use this unit.
