I have the Antec 1200 v3 case, and Asus P8-Z68 pro gen3 motherboard. After reading up on what others wrote about the case and the front usb 3.0, It seems like everyone was saying that the cables that came with their case were just an extension that you have to route outside the case and plug into the rear usb port. The cable that I got is different though... I'm not sure if Antec updated this and I got the new version, but my cable bundle from the front ports has TWO usb 3.0 20-pin header cables. Why are there two, is this normal? Does it matter which one I plug into my motherboard USB 3.0 header, or do I need to connect both of them? I read somewhere else that 1 header powers two usb ports. Sorry if this is a stupid question.
