Hi guys, I am currently building my first PC. I need to connect the front panel connectors, and my motherboard comes with a Q connector. The front panel cable has two sides, one where it connects to the motherboard in different pins. The thing is, I don't know where the side that doesn't connect to the motherboard goes. It is a relatively short cable, and I don't know where else it could go. Do i need to order any new cables?
