Trying to helpl a buddy pickout a power supply but read some issues about the corsairs and ASUS boards and some 780 issues. He has an E8400 and GTX280 in his setup. We were looking at the 750TX Corsair unit but was not sure if this issue I have read about is with all Corsair power supplies or just certain ones. Thanks for any advice. Not trying to break the bank on this one.
