Dell 265 W Power Supply for OptiPlex MT

This 265 watt Dell power supply is built for OptiPlex 390, 790 and 990 mini-tower desktops. It replaces a failed or ageing unit in those specific chassis and restores reliable power delivery. The part matches OEM designations D3D1C, GVY79, 9D9T1 and YC7TR. Buyers who need a different form factor or higher wattage cannot use this unit.

Direct replacement for OptiPlex 390 790 990 MT

The supply fits only the mini-tower versions of the listed OptiPlex models and supplies 265 W. It is not compatible with small-form-factor or ultra-small-form-factor variants of the same systems. Upgrading makes sense when the original unit has failed or when a rebuild requires a guaranteed OEM match. Systems needing more than 265 W or a different connector layout require a different power supply.

Questions about this item

Will the 265 W unit fit my OptiPlex 390 mini-tower case?

Yes, the supply is built for the OptiPlex 390, 790 and 990 mini-tower chassis and uses the standard Dell MT mounting points.

What is the common mistake when installing this PSU in a 790 tower?

Forgetting to seat the main 24-pin and 4-pin CPU connectors fully; the latches must click or the system will not power on.
