Direct replacement for Acer DPS-300AB-39

This Gulfe ATX power supply replaces the Acer DPS-300AB-39 unit found in Aspire and Veriton desktops. It delivers 300 W through a standard 24-pin ATX connector, a 4-pin P4 connector, three SATA power leads, two LP4 plugs and one floppy connector. The reduced-depth chassis measures 5.86" by 3.3" for tighter case fit.

Suits legacy Acer desktop repairs

Builders restoring an Acer Aspire or Veriton that originally shipped with the DPS-300AB-39 will find the connector layout and voltage rails match the original specification. Systems requiring higher wattage, additional PCIe power connectors or a different form factor should look at other units.

Straightforward swap in compatible chassis

Installation uses the existing mounting holes and the supplied ATX 20+4 pin, P4, SATA, LP4 and floppy cables. The unit accepts 115 V or 230 V input with a manual selector. Verify the physical depth clearance and connector requirements before fitting.

Questions about this item

What motherboard power connectors does this Gulfe ATX unit provide?

It includes one 24-pin ATX connector (20+4) and one P4 4-pin 12 V connector for the CPU.

Will the reduced 5.9-inch depth fit inside my legacy Acer Aspire or Veriton chassis?

Yes, the shorter 5.9" height by 3.4" width form factor is designed for increased compatibility with those older small-form-factor cases.

How can I verify the supply is delivering stable rails after installation?

Check that the +5 V, -5 V, +12 V1, +12 V2, +3.3 V, -12 V and +5 V standby outputs are present and that the unit passes its internal over-current and over-power protection tests.
