I have recently set up an additional computer in the same room as my gaming rig (for Bitcoin). I have just been woken up by it going BANG (breaker flipped as well). 
It is (was) a Super Flower 1KW gold unit, running 3 280Xs and the cheapest Intel CPU I could find.
What should I do? Is it dead? There aren't really any other options for re-locating the computer but if the mains supply to this room is inadequate I need to know.
