How many watt for this build?

[fevion]

Hi, I'm changing my PC and I'm wondering if my EVGA SuperNOVA 850 G2 can sustain this build:

• 
  i7-7700k OC 5,2ghz 1,35v
  Gigabyte Z270x Gaming 8
  (2x16GB) G.Skill DDR4 Trident Z 3000 Mhz PC4-24000 CL15 (15-15-15-35) 1.35 v
  x2 Aorus GTX 1080 Ti Xtreme Edition 11GB GDDR5X
  Samsung 960 EVO M.2 500gb
  HD 7200 rpm 2TB
  HD 7200 rpm 4TB

Custom watercooling:

• 
  x6 Noctua 120mm Fan NF-F12-PWM
  Pump EK-XTOP Revo D5 PWM

I used PSU calculator but I'm a bit confused with some values, so I prefer be sure asking to someone.

Thank you very very much.

Get around a 550-650 watt. That should be all you need for your system

Agreed 550-650w.
Due to overclocking and watercooling with seperate pump I would shoot for 650w..

Note that PSUs are not created equal. There is a HUGE difference between that $40 650w PSU and the $80 one. The $80 one can actaully ouptut 650w, do it efficiently, and most importantly it is not a ticking time bomb that will fry your parts when (when not if) it dies.

For your setup I would get a Sesonic/Superflower Gold rated PSU, or EVGA G2/G3.
