I just got my video cards in today. I haven't installed them yet but I have an evga GQ850 and I'm trying to figure out if it has enough power for my system. The other components in my system are
i7 6950x, 64GB of memory in quad channel, and 1 NVME SSD one or two 1TB SSD's and 2 4TB hard drives.

Just would like to know if my power supply is enough.

No. The wattage calculator I use shows you using right at 800 watts with just one of those cards and 32 gigs of RAM. You will have another 32 gigs of RAM plus a second GPU, a model that uses up to 180 watts. I was also only able to put in one SSD and one hard drive. So even at stock speeds, you are going to have trouble. You need to get a good 1000 watts to be honest.
