i plan on building a system with 1 gtx 780 but i have a feeling in a year or so i would like to upgrade to 2 in sli. Will a 850w psu be able to support 2 gtx 780's. System specs are as follows:

intel i5 4670k
asus maximus vi hero mobo
corsair 2x4 gb 1600mhz ddr3 ram
wd black 1 tb 7200rpm hardrive
ssd (undetermined)
cm v8 gts cpu cooler
standard optical drive
gtx 780 (possibly x2)


So ya do you think it will be enough.
Thx

Solution
Put your system in a PSU calculator. The Newegg PSU calculator put the figure at 912 watts for typical system with 1 HDD, 1 DVD, and two GTX 780s.
