Need a new Motherboard for 800$ gaming desktop

I am building a new gaming computer, everything is pretty much set in stone, but my current motherboard was out of stock, and I am planning on buying this computer within the next 2 days. I need help finding a new compatible motherboard. My budget is bellow 150$, I would love to have SLI for the future, but its not necessary if my budget is too low. Also It would be great if anyone could tell me how to know how much watts I would need although I think my current PSU is ok.
