Hi everybody. First of all, sorry for my poor english. I´ll try to let me understand. I have a friend with a 5500 XT. Its using with an older NOX 600W PSU, and sometimes when its gaming, the PC restart (playing COD or fortnite, 1 sec of black screen, and then restart the whole PC). We try to configure the Adrenalin to ECO MODE and the restarts ended, but then we have that 1-2 secs black screen during gaming, and then back to the game. He tried with a displayport cable with the same results. What do you think? Must be the PSU? Im thinking that if we are putting it into ECO MODE, maybe when the graphic card needs more power and because we have it into ECO MODE....maybe its because of that?
