I was building a system comma and when powering it on the optical drive and hard drive were fried. I changed out the PSU, and once again attempted to power up with a new hard drive., and the same thing happened. The damage on the contacts is clearly from the power supply side the connection comma but I seriously doubt that I got to defective psu's out of the box. Could a bad motherboard cause this Behavior? The psu's were respectively, an EVGA 1300 G2 and a century x+ 750 watt. The motherboard is a gigabyte 990fxa - UD3.

The motherboard doesn't supply power through SATA. The hard drive has a separate power connector directly from the power supply for that. You could have a defective motherboard that has fried its own SATA ports with a short or something. Have you tried plugging the hard drives into different SATA ports on the motherboard?
