You blew up U15 as well? Hm, interesting; wonder why that is failing.

I think that is the 3.3 volt supply line, if you want to send it over I can take a look at it. I'm sure though they will honor the RMA. Drug, did swapping that chip fix it?

Thanks for the offer. I'm in Australia though so probably not worth it for me.
I think u15 blew because I recently changed to an ATX power supply rather than the power brick (all in effort to prevent something like this from happening.)
The sparks came as soon as I un-plugged and re-plugged in the USB cable while trying to get rid of "unresponsive asic" messages in cgminer.
For next time I'm considering wiring in a 30v 6A Poly switch that I have here or maybe a fuse.

Thanks everyone else for the suggestions. I don't have a current limited power supply so this might be a bit too hard to fix myself.
My main issue now is if BFL will try and fix it before sending me a new one. If so they might see that I reflashed to get to 7.8gh/s
