Over last weekend I had my system give a little pop and shut down mid game. I checked all the connections and it was only the system that went down. I was still just hoping a fuse had blown at that time. I was unable to start it back up unplugging the power and plugging it back in I could see the power button flash for a second but nothing was kicking over. I unplugged all non-essential drives and tried starting it again. I could immediately smell burning and looking at the video card which I had left plugged it gave out a nice cloud of smoke. I shut it down unplugged the card and tried to power it up again. The system came up and loaded the os I still had the speakers on so could get that much. I tossed an old 7600 on later and was able to boot up no problem. The card was of the silent variety and did not need power so I have been unable to test the 6pin cables for the gpu. I have an Antec CP-850 in there and had been getting random black screens that recover with the well know display driver has stopped responding errors since the 280 series of Nvidia drivers came out. A few people said it was the card not getting enough power but the fact that it was running fine until 280 and the now 290 drivers led me to think otherwise. Everything is powering up right now but I don't want to chance a replacement video card getting toasted. Not to mention I really don't want to take the chance that my ssd's might get fried. I am thinking a replacement psu is in order. I have an Antec P193 case which is huge so I am looking for a good size modular psu that can make the stretch as it will be coming from the bottom of the system. I am also looking for a replacement gpu. I loved my 570 it took every game I through at it at high settings. I was thinking of maybe going with a GTX 550 for now while waiting on the release of the next gen cards to come out here shortly. I just need something that can push BF:BC2, BF3, Skyrim and SW:TOR at medium to high settings while waiting for the release of the new cards.
