How many watts do I need for my setup?

[andyrocks1234567]

So I'm currently in the process of making a PC and i was wondering how many watts i need in order to play games without my PC dying.

Specs:
GPU:evga gtx 1080 sc
CPU:intel i7-8700k
MB:asus z370-p LGA 1151
Storagene ssd w/128gb and another samsung 850 evo w/ 1tb
Fans:4 including cpu fan(cpu fan will most likely be cooler master)

I would like to know how much I would need with and without over clocking.

A high-end 550W (min) if you don't plan on any OC'ing. If you do, I'd go 600W or better.
