Would 550w be enough to power this build?

I will also be overclocking my CPU and GPU. Will 550w be enough to power the entire system, including the overclocked 1070 and 6600k?

You should have a small bit of headroom but it might be really close. A 600-650w would probably be a good investment here.

Your fine. You don't have the most overclocking headroom, but as long as you aren't pushing for anything crazy, you should be fine.

The 550watt will be just fine. With everything stock you will probably pull a max load of 300watts and overclocked for sure no more than 450watts. Probably 400-415watts. I mean for the small price increase I would go 650watts since you plan on overclocking though.

I have recorded 191watts at the wall with a 6600k at 4.6ghz (think it was 1.296v) during cinebench (cpu benchmark with 100% load). That system had 3x 390x installed so with the 1070 on a cpu load only it would probably be in the 180watt range. That system during Unigen valley benching on a power hungry 390x was doing 348watt on the gpu benchmark. With all 3x 390x on unigen valley it did 888watts so you can see a i5 6600k with the much more efficient single 1070 will be ok with a 550watt even though I think a 650watt would be a better choice.

You should have a little more headroom, especially if overclocking.
