That's a lot of current through some not particularly thick metal. It doesn't surprise me that there was some warped plastic and that the pins have shifted in their sockets.
There was no short circuit, just too much draw through too little copper. Unfortunately that means that odds are the same thing will eventually happen again even if you replace both PSU and motherboard. You could get a motherboard that takes auxiliary power from a molex or SATA connector. Or back off on the overclocks.
thanks for the reply...one more question
4 pin molex built into the motherboard = evga power boost ?
do both of those effectively do the same? is one necessarily better than the other? i'm guessing for functionality wise, the native 4 pin molex built into the mobo is better because it doesn't take up one of your PCI-E slots?
