Adds one Type-A and one Type-C port at 10 Gbps plus a front-panel Type-E header and a 19/20-pin connector over a PCIe 3.0 x4 slot
This PCIe 3.0 add-on card uses an ASM3142 and 822 controller to provide one USB 3.2 Gen 2 Type A port, one USB 3.2 Gen 2 Type C port, a front Type E header and a 19/20-pin header. Each external port delivers up to 10 Gbps bandwidth. The card installs in an x4 slot with gold-plated contacts and includes a low-profile bracket and fixing screw.
The card suits system builders who need two high-speed external ports plus internal headers for case front-panel connectivity. It is not suited for users who require more than two external USB ports, additional internal headers beyond the Type E and 19/20-pin connectors, or a PCIe 4.0 or 5.0 host interface.
Verify that your motherboard has an available PCIe 3.0 x4 slot (or larger) and that your case front panel provides matching Type E and 19/20-pin connectors. Ensure the operating system supports USB 3.2 Gen 2 without extra drivers.

The card uses a PCIe 3.0 x4 interface; a PCIe 3.0 or newer slot provides the full 10Gbps bandwidth per port.
Yes, both external ports are backward compatible so existing USB 3.0 and 2.0 peripherals will function at their native speeds.
Check Device Manager to confirm the ASM3142+822 controller appears, then run a speed test with a USB 3.2 Gen 2 drive to see 10Gbps throughput.
