How can I use the usb 3.0 port on my case?

Solution 1:

Yes, according to Intel's product listing, your motherboard doesn't come with a USB 3.0 controller so there's indeed nowhere to connect the cable to. (Note how it doesn't have any external USB 3.0 ports – that's a good hint that it won't have any internal ones, either.)

You have two options for the cable:

• You could buy a PCI-Express card that comes with its own USB 3 controller. Search online stores for "USB 3 PCIe card". Note that most such cards only have their own USB 3 ports in the back, but there should be a few which have a header for connecting the front-panel cable as well.

• You could buy a cheap adapter that allows those ports to be connected to your motherboards USB 2.0 header. Search online stores for "USB 3 to USB 2 pin header adapter". Of course, the ports will work at USB 2.0 speeds only.

Solution 2:

If your motherboard doesn't have USB 3 then you cannot do anything with that connector.

You might be able to fit and use a PCI-E to USB 3.0 Expansion Card of some kind but there is no way to convert USB2 ports to USB3.
