I am planning on doing this in the near future.. and I plan to leave both GPU's at stock overclocks. my full specs are..

-i7 4770k overclocked to 4.4ghz @ 1.3v
-Maximus VI Hero LGA1150
-Gigabyte GTX 770 2GB version
-8GB DDR3 PC3-10700
-Windows 8.1
-EVGA Supernova NEX750B 750W ATX EPS12V Power Supply 80PLUS Bronze

I've heard mixed answers from various shops... I just wanna hear what the owners of a SLI Gigabyte GTX 770 would recommend or think its safe.

The theory is that you'll be just fine. Under a heavy gaming load you won't be pulling more than 600w DC with your CPU OCed as is and stock 770s. You'll be able to OC the cards as far as they'll go and still not exceed the theoretical limits of your PSU. The only potential issue is that EVGA's NEX line are not tier-1 units, I don't know if it's good for its full rating for extended periods of time.

with 2x770 in SLI normally a 850W is recommended. With an overclocked CPU I think would be the safe option.
Corsair 850W sounds good. It is important to remember that high PSU usage degrades it faster. It will lose efficiency faster if it is pushed high, but you can try your 750 if it doesnt work put in an 850.

I am being more caustious because my girlfriends EVGA GTX 480 got fried from using a no-name 550w PSU also having a overclocked FX-8120. Would it hurt me if I tried? Would it fry up easily?
I also plan on running 2 games at the same time, one on each monitor.
