I am currently running a GTX 780 Classified with an i7 3770K and am looking to grab a second GTX 780 Classified to run in an SLi configuration. I have a Corsair AX 850w PSU and was wondering if this would be doable. Thank you in advance for the reply's!
 
I too, say yes. Those cards have about a 225w TDP. Your cpu is is 77w tdp. This falls well below 850watts and that PSU is considered pretty good.
577watt tdp for your cpu+2 gtx 780s (Stock speeds)
Plenty of headroom, other pc components do not use that much power.
