I am going with Malcador on this one. He took the Emperors place on the Golden Throne. It killed him mind you, but a lesser man would have died instantaneously. Furthermore he made the entire moon of Titan invisible with his Psychic powers. Magnus is awesome to be sure, but Malcador is just plain epic. I think his very existence breaks the rule about humans not being able to go above Gamma level Psychic powers.
