I have a A770M-A mother board that I want to install into a Coolmast case. My mother board supports USB2 and my new case has USB3 on it. My question is can I use the USB3's from my case on my motherboard?
Unfortuantely, the header of USB 2.0 doesn't support USB 3.0 due to the pin settings between two headers are different. For the alternative solution, you can purchase a USB 3.0 PCIe card which came with internal header in order to solve this issue.
