Speed & KO power!!!!?

I do mma I do muay thai, and bjj and stuff like that,but that's not important right now. I use the speed punching style and a fast fighting stance in boxing. I have pretty good power in both hands, but in my right hand I have KO power.(I am originally right-handed, but I wanted more power in my left. So I fight southpaw now) I'm really fast and I have KO power so how would this help me in the cage and out on the streets
