​Hi guys, just looking for a bit of advice.

I'm currently building a rig with the following components;
Asus Z170 VIII Hero Motherboard
Intel i5 6600k 3.5ghz
Kingston HyperX Fury 16gb (4x4gb)
XFX R9 380x DD

My question(s) is this: I'm currently looking at buying a second R9 380x to run in CrossFire configuration shortly after building, the PSU I'm currently looking up is the Seasonic X850 850w, which I selected from the PSU Tier List here www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html and I've used the outervision.com PSU calculator and as far as I can see, it should be fine. Is this enough wattage to power both the cards? I just wanted to see if anyone else has used this setup or something similar, anything I should be wary of with using a higher wattage PSU? Any advice is appreciated.
