Overpower → It is formed from "over-" (meaning excessively or beyond) and "power" (from Old French *poeir*, meaning to be able or to have strength). The word "overpower" means to have excessive strength or to dominate someone or something completely.
Think of having strength that is 'beyond' ('over-') what is needed — that's why overpower means to dominate with excessive strength.
