Can a Power Supply corrupt Bios at first power-up?

Can a Power Supply corrupt Bios at first power-up on a new set-up, the reason I'm asking this is becuase I recently sent two A7N8X boards back, on both I tested everthing out except the power supply, they posted ok, and went into set-up ok made sure all was set properly (not OC) save & exit and it then restarts & does not post, tried clearing cmos, I tried everything I could think of.. never to post again! any one have have any simalar experience, I did finaly get this set-up up and running but just curious if I might have missed somthing in bios set-up, this was the 8th machine I put together (4 A7N8X machines) , can bios or boards be overly sensitive to voltage, or power supplies be off to far This power supply was a enermax 465, 431 watt.
