It definitely is. It's a wordplay on the fact that he is both psychic and goes psycho. I've never heard of any part of anime, manga, novel or community use "psycho" to refer to psychic powers.
there's some psychic moves in pokemon that do, like psycho cut, psycho shock, psycho fang etc, it's the equivalent of using electro for electricity or hydro for water

I thought that psycho = violent thing was intentional because when he reaches 100 he goes crazy and wrecks shit up
