I would get a WAY better cpu cooler than that, if you're gonna have a i7-6700K, I would definitely get something better than a Hyperr 212. Especially if you're planning on overclocking it at all, that wouldn't be the best for your cpu seeing that I've seen CPU's fry cause of shit like this.
Many PC's don't need that much watts, anything over 600 technically is overkill. It's just good for your PC to have more watts available than just whats required.
