Not sure if PSU will be enough if I decide to go SLI in the future.

I'm not sure if the 650w PSU will be enough. When I add another GPU in on partpicker it says that it won't be enough, but I've heard people say that a 750w version of this PSU will run Titans in SLI without a hiccup. Note I will be over clocking both CPU and GPU.

It won't be enough, as you'll be about 50W over the limit (your system will consume 474W assuming everything runs at maximum wattage, and another 770 will take 230W, putting the total at 704W). Of course, a PC isn't always going to run at max power, put if you plan on overvolting when you OC, you'll need extra headroom. Also, I believe that PSUs are most efficient at 50-75% power draw. Not sure if that's true, but it's something to consider. I'd get the 750W version if I were you.
