I have an asus gr8 ii pre-built specked with an i7-7700, 16gb of ram and a gtx 1060 3gb. I would like to upgrade the gpu especially when rtx 3000 comes out but I don’t want to spend so much money on a whole new pc. The main problem upgrading the gpu is the power. The gr8 ii comes with a 230w power brick wich isn’t enough to power more recent gpus and I’ve heard about something to do with dual power bricks but I’m not sure. And then with the power out of the way is there any more problems that I could encounter??? On a side note could buying an e-gpu work.
