Well at least you didn't have a Bestec so you stand a reasonable chance of everything being ok. I've seen a couple of cheap ones go, one took out the USB ports and the other was fine. My previous one died a horrible death (complete with fizzling and bright sparks!) and that was from a pretty large OEM manufacturer, thankfully it was probably the protection laying down its life to save my components.
You won't really find out anything till you plumb the new one in, so fingers crossed:)
