Is 8 Pin power connector bad if only 4 Pin is needed?
I was wondering if plugging in the whole 4+4 CPU power pins would be damaging in any way if all that is really needed is the 4 Pin. I have an AMD FX-8120 3.1 Ghz, and my plan is to O.C. it sometime in the future as a way to avoid getting a new CPU until I really need to.
The base power requirement for my CPU is 95W and (correct me if I am wrong) it is my understanding that one set of 4 Pins supplies 150W. I haven't done anything with O.C. so i dont know how much power I will ultimately need once I decide to O.C. But while I have my PC open I thought I would check to see if I could plug the whole 8 in without consequences, so that when I am ready, in the future, to O.C. I can just start bumping it up without having to open it up just to plug it in (lol sounds pretty lazy...) if I had to. I would assume that it would only take the power it needs and not try to force it all through... but I won't use my assumptions as a basis to go ahead and experiment

No it does not hurt plugging in all 8 regardless of which CPU is installed. The CPU only uses the power it needs.
The extra 4 pins are for auxiliary power - it helps, somewhat, with overclocking & overvolting.
