This PCIe USB 3.2 Gen 2 card installs into an available PCI-Express slot in your computer and enables you to upgrade your current system by adding two USB-C™ (10Gbps) ports.

Faster USB Performance

Also known as USB 3.1 Gen 2, this USB 3.2 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 3.2 Gen 2. With higher data throughput support, this USB 3.2 Gen 2 PCIe expansion card is a necessity for external drives and many other USB 3.2 Gen 2 peripherals and includes an optional SATA power connector for high power devices.

The card is backward compatible with USB 3.2 Gen 1 (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.
