Well I am astonished that a Corsair allowed this, it is NOT a 1 or 2 cycle short; its supposed to under/over and fault protect. I would contact Corsair and show them what happened.

Clearly, you had a catastrophic failure, one of the worst I've see, and by the looks of it I can only imagine someone or somehow the equivalent of pure A/C going into the MOBO.
I would be VERY surprised if your CPU survived; more like a miracle. I would be surprised if ANYTHING connected to the MOBO wasn't damaged.
