Very solid build! As Sagittarius said you don't need 750w PSU, i recommend the Corsair CX550M or CX650M. They are pretty cheap, but also very reliable and high quality! Just remember it is CX650M and not CX650 (The old ones are very shit)
I have a Corsair CX650M in my build with I7-6700K at 4.6GHz and EVGA GTX 1080 FTW and it is going like a champ!
For CPU Cooler i strongly recommend the Cryorig H7, it is a little better than the 212, and it looks BOSS, especially in your white/black theme! I always use it as my goto aircooler when i build for people!
