Is my motherboard faulty or did I do something wrong?

[/quote]I just tried to put together my new PC yesterday, and the transformer in my PSU blew out. I'm worried that I may have used the wrong cables to power my board. The board requires an 8 pin connector to power the CPU. However, I used a PCI-E 8 to 6+2 pin cable. Could that have caused my psu to go out, or did my motherboard cause the burn? Also, could this have ruined my cpu?

Your PSU may have just been faulty, but since you used a pcie connector for your cpu connector, are you sure it was in all the way? If so, then it might just be the fact that you overpowered your CPU, and with overvoltage protection, it might have shot that power back to the PSU. I recommend only using a connector labeled for CPU power only.

I'll add pictures of the connector I used. I'm very unsure if it was plugged in all the way, there was a bit of plastic that needed to be filed in order to fit into the psu. I highly doubt that it was faulty either, it was working hours before on my old computer.

Corsair PSUs often have the problem where the 24 pin power connector won't clip all of the way, as the system has about 3 seconds of life and then stops working. Exert some more force to get it in all of the way and it should boot fine. I should know, because this happened to me!

I uploaded a second picture showing the cable I used after filing it to fit. I did have troubles plugging it in, but could that have caused the transformer in my PSU to go out?
