I am building a gaming pc for my roommate. I have gotten him a radeon rx nitro + 5700 xt, the computer is not freezing nor is the game crashing but it is freezing up temporarily during gameplay. the card has 2 8 pin pcie slots and i. Am using a 700w thermaltake psu, i suspect that its not getting enough power because the 2 8 pin pcie ports are split up on one cord. Does the card require 2 SEPARATE 8 pin cords?
