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.

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.
