You didn't need even half of 850W for that system in the first place.
^ Noctua's chromax.black fans come with white corner pads in the box, which should look quite good in a white themed build. The included fan that comes with the U12S could go in the rear of the case, instead of the stock Corsair fan that is there by default.
The 680X RGB comes with Corsair's Commander Pro fan/RGB controller, so you don't need tons of fan headers on your motherboard.
