I am in the middle of my work station PC build. I have an ASUS B450 and a 6000D case. The case has as a USB input. It also has a 3.0 cable. My ASUS mother board has a male 19 pin header that connects to the case USB cable. My MB Manual states the following: "This motherboard does not have a USB 3.0 module. It must be purchased separately". I don't get it. They build the MB with a 3.O header but fail to install the appropriate module. I am really confused on this. I can buy a card which has all of the USB headers, but why. I guess I can attempt the OS install. If I receive the error about no USB connection, I will need to get the card. Will the USB port on the rear of MB work. I am so pissed at ASUS. They even failed to send me the proper mounting hardware for the M.2.
