I'm currently deciding between the CORSAIR RM650 and EVGA SuperNOVA NEX650G but I noticed the EVGA has 4 12 rails and CORSAIR has one. Should I buy one over the other just for the fact alone?

side question: The RM750 is currently the same price as the RM650. If I should go for a single rail, should I just get the RM750 so I could still use it further down the road when I build more powerful units?
