850w PSU enough for Gtx 770 sli and expansion later?

[LevelXAbstract]

Hey,

I'm about to purchase a large upgrade for my computer. I'm intending on purchasing a Corsair AX860i platinum. I know its a quality power supply, but how will it fare with my intended system.

2x Gtx 770 in SLI.
i7 4970k
8gb of Corsair Ram at 1600mhz, will likely be upgrading to 16gb later
Either a Corsair h100i or a bequiet dark pro 3.
Asus VII Hero ATX mobo
2x ssds (will likely buy another 1 or 2 later)
2x hdd at 7200rpm (will likely buy another 1 or 2 later)
As well as 4 or 5 case fans, which will not likely be led.

by what you have posted id get the 1k corsair its better to over do it and not worry than under do it and be stuck with an expensive desk wight that doesn't boot

You will be fine with the Psu you have selected. You may consider getting a decent 1000w if you feel you are going to overclock the gpus or if you keep adding extra stuff inside.

Go forth and conquer!
