With previous dell models like the optiplex 780 s 790 s and 7010 s i would just install a cots 500 watt or higher power supply and we would be good to go.

Dell optiplex 7020 power supply upgrade.

Or you get a moddiy adapter and you can use an evga 700b1 power supply. Back then a company called pc power and cooling began building power supplies based upon the dell proprietary design. Dell optiplex xe2 9020 7020 3020. This is a proprietary 8 pin instead of 24 pin power supply.

Upgrade psu for a dell optiplex sff 7020 jump to solution the motherboard for this optiplex is very strange the pcie 16 slot is at the end located near the psu and their is not more slots next to it but i just thought of using a pcie extender to make it compatible unless it affects performance. So i sought them out to see if they had optiplex 7020 compatible power supplies. Theres even a guy who modified a power supply to work. With this new bastardized 8 pin power supply it looks like we ll have to find a different model of dell.

Its 8 pin atx motherboard connector looks identical to that used by optiplex 7020 3020 9020 but the exact pinout has not been verified to be the same.
