Faster USB Performance

Also known as USB 3.2 Gen 2x1, this USB 3.1 Gen 2 card adds two 10Gbps USB Type-C™ ports to your computer.

Utilizing an ASMedia ASM3142 chipset, this card harnesses the speed of USB 3.1 Gen 2. With higher data throughput support, this USB 3.1 Gen 2 PCIe expansion card is a necessity for external drives and many other USB 3.1 Gen 2 peripherals and includes an optional SATA power connector for high power devices.

The card is backward compatible with USB 3.0 (5Gbps) and USB 2.0 (480mbps) devices. The card works with newer USB-C devices, but can easily support your existing USB-A peripherals using inexpensive USB Type C cables and adapters. See our Accessories Tab for supported options.
