It's more technique than power. U gotta line up your knuckles with his jaw line. Try to use primarily your second and third knuckle. Good technique with ok power should do it, but if you want to make sure u get that knockout great technique with good power will do it. Be careful though, u knock him out and he lands on his head, you'll go prison for manslaughter
