Dell Optiplex MT Replacement

This 180 W power adapter replaces the original unit in Optiplex 3900, 3901, 3990 and 3991 MT desktops. It also fits Inspiron 3910, Vostro 3690 and 3710 systems. The combined 8+4 pin connector matches the motherboard socket on these models. Builders restoring a failed power supply in one of these towers will find a direct fit.

Wide Input Range

The adapter accepts 100-240 V at 50-60 Hz with a 3.0 A draw, so it works on mains worldwide without a voltage switch. Maximum output is 180 W, matching the factory rating for the listed Dell MT chassis. No extra cables or configuration are required beyond plugging the combined connector into the board.

Compact Form Factor

The brick-style housing is built for the tight space behind a micro-tower motherboard tray. Its combined 8+4 pin plug eliminates the need for separate ATX and CPU power leads, reducing cable clutter inside the case. Systems needing a different pin layout or higher wattage will not be compatible with this unit.

Questions about this item

When will the 180 W power adapter need replacement?

The unit is new and carries a one-year warranty; plan to evaluate it after that period or if the Optiplex 3900 shows power-related instability.

What limit appears first during continuous full-load operation?

The adapter is rated for a maximum output of 180 W; sustained draws at that level will hit the power ceiling before any other constraint.

How much heat or noise does the 8+4 pin adapter produce when running all day?

It accepts 100-240 V at 50-60 Hz and draws up to 3.0 A; typical operation stays within normal thermal and acoustic ranges for a 180 W desktop supply.
