Guys -- a noob question:  

I have a Corsair 1200i that I'd like to replace the S2's Enermax PSU.  However the pinouts aren't compatible ... can't plug in the motherboard plugs from the S2 into the modular connection of the 1200i.  Is there an adapter I need to use?

Thanks!
You need to use cables from your Corsair 1200i. I'm guessing you just disconnected cables right from the PSU, am I right?
This. Remove all the power cables that were in the S2 and start again.

I removed half the modules and unhooked the power cables to the motherboard.  The new cables from the Corsair fit perfectly ... so your suggestion worked.  Thank you!

Tried overclocking to 212 and getting 2-3% reject rate, despite the better PSU.  Going to try to scale down a bit to see if it makes a difference.
Chips are voltage limited very quicky, and swapping out the PSU is more so to prevent the old one from blowing up when pushed.

From my experience, it seems that overclocking the S2 just makes little sense.

Replacing the PSU (and paying an extra $350) + increasing load by 0.5amps just to get an extra 50 GH/s seems more risky than the value it will bring.

Would love to see what other people think.
