Dell optiplex 7020 power supply upgrade.
Model d315es 00 power supply 315w dp n 0vx372 dps 315cb vx372 is officially for optiplex xe2.
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.
4770k would require the optional 365w power supply.
Back then a company called pc power and cooling began building power supplies based upon the dell proprietary design.
With this new bastardized 8 pin power supply it looks like we ll have to find a different model of dell.
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.
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.
Or you get a moddiy adapter and you can use an evga 700b1 power supply.
