I got a MSi RX 580 gaming GPU last weekend and i was getting screen flashes on loading screens for games. today i tried to play fortnite and same thing then my PC shutdown. after a few seconds my PC restarted and my ASUS Z97-AR LGA 1150 Motherboard told me my PSU send power surges so to protect the mobo it shut down. Cool, i already bought a Seasonic Titanium Prime PSU and should have it in two days. My current Enermax was purchased in 2007 and was proabably fine with my R9 270 GPU but now that i need an 8 pin connector i am pushing too hard too late in its life. My Enermax is a 720watt unit but probably just on its last leg. now i want to avoid gaming until i can change it out so i don't break any components.
