Decrease clocks or get another PSU for the software you are running!
You see, voltage is not the issue as voltage is only electrical potential, it allows current to flow but only when needed like when software starts to load the card, the "harder" is the program for the card to run, the more current will draw from the PSU! Higher clocks only make it more power hungry!
A GK110 mining with 1,180V draws over 400W from the PSU! Lets give it 350W for each card@1200mhz, plus 180/200W for your OC'ed CPU and the rest of the system and clearly you see you are at/over the limit there!

I've never had an evga card before, but i can talk very well about twin frozr cooler wich i suppose it's one of the best on the marker for silence
Its 2 completely different cards! Classifieds are in a different league that MSI gaming, EVGA Classifieds have their own voltage controller tool and very good VRM modules, MSI gaming is only a reference card (unlike the Lightning)!
Either way you will loose about 20/30% performance from 780SLI into single 780Ti!
My 2 cents
