Hello Toms I been having issues with my system I put in a new Corsair 850hx a month ago, and when I did I fried all my 12v components (mobo,2 5870's) Got psu warranty, and xfx replaced my gpus. I just watercooled my 2 gpu's and they fried again. (they were working before the waterblock install) Built several systems and have not have issues like this. I pulled everything out and went over every inch of cables to see if there is a short, and nothing. I am at a loss any ideas??
