I'm still pretty confident it is not the PSU. Could be a weak link with SLI software and two overclocked BIOS modded cards, could be a voltage regulation issue (not a wattage problem), could be one card not playing nicely with the other one with custom overclocks (happens VERY frequently). It took me forever to get my 560s overclocked and happy together.
I'm really familiar with the Skynet bios(s) and they are far from perfect. I recommend anyone that's willing to modify bios to use KBT and modify the stock bios (after carefully saving the original of course).
