I had the club3D Royalace R9 290 recently installed and completely forgot I probably needed a better psu as well. It only delivered 500W. I thought my previous card (hd 7970) needed more watts than the 290 (thought I read it somewhere). The hd 7970 broke down under guarantee and i decided to upgrade instead of having it replaced. I was very happy playing bf4 on ultra but after half an hour the pc shut down entirely and now the power led won't even light up when I try to start it. I figure the psu broke down. My question is: "Is this the case and if so, is there a risk other components have broke down as well?"
