So this is my build here on PCPartPicker.com and I am wondering how many watts it will consume.

Note that I will be adding a second GTX 1070 in the future and will only be overclocking the i5-8600k as high as the silicon lottery allows, hopefully at least 5GHz.

I will also be adding another identical set of 2X4GB of RAM to this build later.

I would like a little headroom for future proofing beyond this as well.

I have used multiple wattage calculators online but I have gotten wildly varying answers doing so and would like some experienced help. I am guessing somewhere around 650-750 but I'm not sure if 650 will give that future proofing I want.

Any ideas are appreciated and considered. Any questions, please ask. Thank you.
 
Solution
For single GTX 1070 - 500W is recommended, for 2 cards in SLI - 650W minimum (without OC).
For OC add some reserve. So realistically you'd have to look for 750W-850W PSU.
