Hi, I have here the "top" PSU from OCZ and was wondering if its a bad idea to push it to its listed limit of 1250 watts. I have a massively OCed i7 2600k and I want to take my pair of 680s to a 40% OC but im not sure if the psu can take both of them at once. It has worked fine with one card at a time and i want to make sure i dont kill it with both.
