Not even close to reaching 750W. I'd say somewhere below 600 when gaming mabye 650 under synthetic load.

who cares...

Not mine. A friend of mine bougth a 4770k a single 780ti and a 750 Watt RM Series. And a couple minutes ago he asked me if he could SLI with that PSU and i told him that it should work. (He is mad because of him only getting 33 fps in Crysis Maxed @1600p)

That's pushing it, i would get some more.

well it all comes down to what cooler he has and extras that drain the power, cause then we can fully work out if it will be able too

well turn the AA down to about x8 or x6 then he might get some good fps and still look great, you don't need lot's of AA unless you are running some rubbish Resolution

Will a 750 watt 80+ Gold. be enough to power a 4770k and 780ti SLI? 

nope...

 

i would not recommend that. I think it woudl not even be enough of everything is unOCed. I recommend you to get a RM850..

 

Check a PSU calculator on the internet.

thats close to the furmark test on anandtech(652W). however, furmark is a totally unrealistic scenario. in games no card will suck up that much W. and its bad for the card too. thats why they throttle

Yeah it should be able to handle it but you will be limited in terms of overclocking as there isn't much headroom imo.

GTX 780 TI can pull up to 300W of Power.  So 2 places it at 600W and an overclocked I7 puts you right below 750, not adding in extras.
