This PCIe USB 3.2 Gen 2 controller card installs into an available PCI-Express x4 slot in your computer and enables you to upgrade your current system by adding two SuperSpeed USB-A (10Gbps) ports.The controller card enables you to connect two USB-A Gen 2 (10 Gbps) devices to your desktop computer. The USB-A ports are ideal for connecting USB devices such as external hard drives and solid state drives or powering and syncing your mobile devices. The USB-A ports provides up to 4.5W (5V/0.9A) of power per USB port, and are backward compatible with USB 3.2 Gen 1 (5 Gbps), and USB 2.0 (480 Mbsp) devices.The USB 3.2 Gen 2 card features an ASMedia ASM3142 host controller that utilizes x2 lanes of the PCIe 3.0 bus, making the card capable of speeds up to 10Gbps on each port, and enabling fast access to high-performance devices like NVMe drives and SSDs. The controller card supports Multiple INs to reduce bandwidth loss when multiple devices are connected, even when connected through a USB Hub (Note: The USB hub must also support this feature).
