So I'm building a new system having a 4790k (planning to overclock) and a single 980 ti for now but planning to have another 980 ti in the future. I have gathered my parts in pcpartpicker and the total wattage of the system reached to 701W. Keeping in mind that I also want to have a custom water loop in here, how much wattage should I opt for?

850w would be good.  but id go with a 1000w to account for capacitor aging + overclocking.

I'd go for an 850w to 1000w. I use the latter just to be safe, more upgrade potential.
