I always recommend Corsair, Seasonic and Antec PSU's. I have had 5 or 6 Corsair's and never an issue. 2 boards in 6 months is not normal, but possible. But, I would replace the PSU if for no other reason than to eliminate that possibility. And an electrical storm will do it. If it enters through the PSU, the better quality ones have protection for that, cheap ones don't. But, electricity will many times enter through the ethernet cable. Nothing is going to stop that. (I know from experience), except a good UPS that the cat6 passes through.
