This is my first build (definitely not my last), I am starting with 2 1080Ti's and then adding until I have 8 GPUs. The parts are listed in this link https://pcpartpicker.com/list/M4N3nn It says the rig will be around 636 Watts. I am getting a 750 Watt PSU so I am not sure if I should get two PSUs now or later.
Any advice is helpful. Thanks!
