I was playing skyrim with insane amounts of texture and shadow mods for about an hour then my PSU surged causing my motherboard to fry. I know for sure that the wiring in my house is fine so I'm guessing that it was a faulty PSU. But I was wondering if skyrim with the mods may have caused it. I have a 780 so I was still getting above 60 fps and I have a 750w PSU which I asumed was enough. So can games cause surges or was it faulty?
What's caused my power supply to surge?

It may have been a random failure, or it may have been too old and finally gave way, or it could have been overstressed and died.
A 780 is a pretty power hungry card but a good 550W unit could run it, but a bad 750W unit may not be able to.

A demanding game increases the load on the CPU and GPU which increases the load on the PSU, but it should not result in a surge or other failure unless something in the PSU was unable to supply the power due to a preexisting weak component.
A PSU dies because there's a defective component. Trusted sites that test PSUs usually increase the load above 100% and only a few low quality units blow. There's no way your PSU was loaded at close to 100% with your hardware; as hunter315 wrote, a quality 550W PSU is enough for that system. Play Skyrim and don't worry about the PSU. Even the best can sometimes fail.
