I wish I could've cracked the PS case to see what actually happened... of course that would've voided my warranty and I wouldn't have gotten my $70 back...
As for those of you talking about fuses and protection, I sure hope these more expensive units have protection! I've seen way too many power supplies take the motherboard with them (then again, maybe it was the other way around... most were old K6's with generic PCChips mobos).
