[X-Men] Is Professor Xavier so smart because of his powers? Or are his powers so strong because he's so smart?

Or is he just a genius who happens to have crazy mind powers? I find it hard to believe there's no connection.

His powers are quite extraordinary, he is the world's most powerful telepath.

He is intelligent, but not much more than your average geneticist.  But he has more experience dealing with super powers than anyone else.  His powers also make self-education easy, as he can read the mind of someone who understands something and pick out any knowledge he needs.  So his powers enable him to use his intelligence optimally.

Right now Red Skull has Prof X's powers and he's being pretty dumb about using them all, so that's an answer all in itself.
