[URL] 3020 MT PCIex16 slot allows up to 75W for add in card. max card length 4.5”. GTX 1650 is 75W.  recommended psu is 300W.  3020 psu of 290W.  You need to check vendor and make sure card does not require additional power connector.  It appears the gddr6 model by some vendor has the extra connector not supported by 3020 psu.
Hi everyone, I have the Dell OptiPlex 3020 MT with an i7-3770 and 8gb ddr3 RAM. I want to install a graphics card into the OptiPlex, and I thought the Nvidia GTX 1650 Super would work. With further research I found it wouldn't fit into the system. Therefore, would a GTX 1650 run fine in the system considering the power consumption?  Many thanks for all of your help, its all appreciated. Jacob.
