To be brief, I have a HAF X Cooler Master Case that I'm using for my first build. Almost everything is assembled and sitting on my work table.
But I have two, blue USB cables that I don't know where they go, or what they hook up to. They start at the two USB ports on the case face, and they are rather long. The ends of the cables are regular USB cable ends--just as if you were hooking up any USB device to USB ports on any computer.
I don't see anything on the MOBO that would accept the USB cable ends. I know I have to plug them in somewhere in order to get power to the ports on the face, but I'm stumped.
Thank you for your help.
That case was made before the implementation of the 20 pin internal USB 3.0 slot I believe. You have to run the cables out the back into your motherboard's I/O panel's USB 3.0 ports.
