If by 'powers' you mean 'the manipulation of chi', he would still win. If you'd read by post before you'd know that there is no way for Goku or anything else to be living without chi inside them. Just because he doesn't have the ability to use chi doesn't mean it wouldn't still be inside him. And with chi inside him Supes' attacks would be pretty useless as Goku's strength would not have really diminished. Plus, as stated by so many before me, before he even had the ability to use his own chi Goku was easily capable of destroying boulders in a single grasp. Look at the very first Dragon Ball tankobon if you want further info on it. Let's not go to that extreme. Without any powers Superman can handle himself okay, whereas Mr. Satan considers a 'feat of great strength' to be breaking through a few tiles one-handed.
