Scilly.Suffolk-
By a tiny amount. But the components aren't pulling anything like their maximum power rating. Here's a review showing a GTX 1060 at about 120 W at full whack: http://www.tomshardware.com/reviews/nvidia-geforce-gtx-1060-pascal,4679-6.html

An 850 W, £150 power supply is overkill.
GTX 1060 official spec says it needs 400 W and an i7-8700K less than 100 W. The other components use barely any power.
Use one of the online calculators but will be surprised if you need over 450 W.
