I happen to have two power plug in's on my Asus Maximus V Formula motherboard, labeled EATX12V and EATX12V_2. #1 is a 6 pin (maybe 8, dont remember) plug in, pretty big, #2 is a 4 pin. Only the first is plugged in and I have a stable 4.5GHz OC. Should the second be plugged in? I wouldn't personally think so since I have a huge OC and am stable without it, but just curious. Perhaps if I plugged the second in, I could achieve an even higher OC? That's just my theory at least, what should actually be done? Anything?
