I plan to have either a 6700k or Ryzen 1700x paired with a 1080ti in the NCase M1 and I plan to have a dual radiator build in there at some point with the Swiftech Apogee Drive II. I also plan to do some overclocking, but how much depends on what the temperatures are like stock. I do have a shortlist of PSUs that I can go.

Which one should I spring for, considering the fact that SFX-L PSUs are a tight fit in there?
I mean the 1080ti, not the 1080. Surely that draws more than 300W watts?
The whole system wont draw much more then 300-350 watts at full load even with a GTX 1080 Ti and overclocks on everything
Even if you added a full liquid cooling setup with pumps and fans and all that the power draw would still be less then 350 watts for the whole PC
Modern PC hardware uses far less power then everyone think and assumes it does
Another point is you are never going to load both your GPU and CPU at 100% at the same time which means all the max power draw graphs you see on reviews are irreverent to real world usage.
Edit: 600 watts alone is overkill for the system you are going to have and you have enough power for TWO GTX 1080 Ti cards if you dont mind cutting it close
So yes the Corsair has more then enough for a system with a single GTX 1080 Ti in it.
I have a n case with the SX700LPT, that extra length does make the different, and if you do intent to add a watercooler, frozenQ sells a custom made reservior for the ncase, although there cutomer service sucks, and unless you live in the US, their shipping is super expensive, I had to use a shipping agent which is cheaper.
