2- Intel i7-4790k Devil's Canyon
3- Nvidia GeForce GTX 780
4- Corsair H105 liquid cooler
5- (x4)8GB = 32GB DDR3 Ram Memory
6- (3)LED Fans + (6)PWM Fans = Total (9)Fans
7- (1)Samsung Evo SSD, (1)HDD and (1)External HDD via USB 3.0
8- ASUS Dual-Band Wireless-AC1900 PCI-E Adapter

10- 2-Port PCIE USB 3.0 Express Card

your psu has more than enough watts to run all this, however Corsair RM power supplies are not particularly good when it comes to capacitor quality, so if you can upgrade, i would strongly recommend doing so...something like

XFX pro 550w http://pcpartpicker.com/part/xfx-power-supply-p1650xxxb9 or
750w if you intend to sli soon http://pcpartpicker.com/part/xfx-power-supply-p1750xxxb9 would be good budget options

For a slightly higher-end unit
Seasonic G 550w http://pcpartpicker.com/part/seasonic-power-supply-ssr550rm or
750w for sli http://pcpartpicker.com/part/seasonic-power-supply-ssr750rm are good options

No your 850 watts are enough, but i would rather go for the ax 760i or the 860i because its higher end and since you have all these great parts. The PSU that I am getting is the seasonic KM3 750w PSU. I am getting a lot of the same things you are. But if I had the money I would definitively go with the AX860i.

550 isn't enough, 600 at least. Well actually those are good enough I guess, but i don't recommend going at the bare minimum.
