Installed on pci support, can help you easily connect the device to the c-type interface. Using gen1 signal, the transmission speed is up to 5gbps, because the 19pin motherboard design has everything (ie usb3.0 5gbps", so how fast the motherboard transmission, how fast the transmission Supported system: All systems that support usb3.0 can be used, and a motherboard or expansion card with socket and a 19pin chassis with TYPE-E cable are required.
