I have a 570 1280mb 3 way sli setup. I have a 500 watt power supply which I can play blade and soul SimCity 4 and a few games but when I try to play destiny 2 the game says graphics not initializing error. I know that a 500 watt is insufficient but will it REALLY fix THIS issue or is it a waste of $50??? I’m having this issue primarily with destiny 2 not so much my other games.
