Question about sli and EVGA gtx 780 Ti classified.

[Executeorder66]

So I'm buying my pc on Friday with just one EVGA gtx 780 Ti classified.
I'll be buying the PSU Corsair atx 860i Watt 12V/EPS 12 V.
Now i would like to know if this is enough or will I also need a more powerful PSU?
Thanks in advance.

860 can do sli with 780's (non Ti) but not sure is it enough to do with Ti's.
Id get better psu. and this is better.

Id just look this to come on sale with 160$ price.

800w is good too.
