Is this a good PSU for my build?

[DogeTheDog]

Hello everyone! I'm sorry I put this question under the Systems category, but I couldn't find a power supply category.

For the last 3 months, I have been planing to build a PC, and finally decided on all the components except for the PSU, I have this one in mind:
EVGA SuperNOVA 750 G2

Do you guys think it's good enough? This is the rest of my build:

• 
  WD Black, 2TB
  
  Seagate FireCuda Gaming SSHD 1TB
  
  Kingston 120GB SSD
  
  Intel Core i7-7700k
  
  GIGABYTE GA-Z270-HD3P (rev. 1.0)
  
  G.SKILL Ripjaws V Series 32GB
  
  Corsair Hydro Series H100i V2

I already have the case, that's why i didn't list it. Please be nice. It's my first time building a PC (or posting here, for that matter.)

Feel free to give me suggestions on parts.
Thank you in advance for your time,

Signed, DogeTheDog.

EDIT: I knew i was missing something! Thank you, CountMike, for pointing out the missing part

I'm not sure which brand i'm going to buy my Graphics Card from yet, but i know that it's going to be a GTX 1080, and likely an over-clocked/over-clockable one. I'm considering Gigabyte, but there are so many different ones i don't know which to choose. Help on that front would be appreciated as well.

You need to count in GPU too because it's single most power hungry component but 750W good PSU should cover any reasonable single GPU

Hello mike, I have edited the post and added a Graphics Card, well, sort of.

You should be OK with that PSU unless the GPU is one of those monsters like XFX Ti version.
