Hi, I bought a new graphic, I had a 750ti 2gb and I bought an 8gb rx 580, my PSU is a NOX uranium 600w, and my FX4300 processor. When I connect it all correct the pc goes without any problem, but when I start a game between 1 and 5 minutes it turns off the pc, I think it must be lack of power, but I would like opinions and recommendations.
