Was playing a game of SC2 when I noticed one of my gpu temps (the one closer to the PSU) went from 55c to 77c almost instantly while the other card was chilling at 58c. I then noticed a faint burning smell and before I get to the chance to shut the game down thinking it was from my gfx card the computer shuts down and I hear this clicking noise so I open up the case and hear that the clicking is coming from my psu and I can't even touch it due to how hot it was. Not an over exaderation or anything but if I was insanely hot. I tried cycling the switch on the back but everytime I went to power it back on the same clicking noise so I left it off for about an hour or so came back when it was cooled off and now it powers on fine. I am very closely monitoring my temps right now and not putting any major loads on it until I know this won't happen again. I also blew out the psu but not much dust came out. Anything like this happen to yall? Do PSU have temp fail safes?
