Adds two 10 Gbps USB-C ports via a PCIe x4, x8 or x16 slot, with a low-profile bracket included
This PCIe controller card adds two USB-C ports to a desktop system, each capable of 10Gbps transfer rates. Both ports can operate at full speed simultaneously for high-throughput peripherals. It targets builders who need fast external storage or device connectivity without using front-panel headers.
The card only functions in PCIe x4, x8 or x16 slots and will not work in x1 or x2 connectors. A PCIe 3.0 slot paired with USB 3.2 Gen2 devices is needed to reach the rated 10Gbps per port. Windows 11, 10 and 8 install automatically; Windows 7, Vista and XP require a separate driver.
The USB-C connectors carry data and power only and do not support DisplayPort Alt Mode or any video output. This makes the card unsuitable for docking stations or monitors that rely on USB-C video. It comfortably handles dual high-speed SSDs or docks, but cannot drive a display link.

Each USB C port can reach a maximum transfer rate of 10Gbps, and both ports can operate at that speed simultaneously when connected to USB 3.1 Gen2 devices.
The card needs a PCIe x4, x8 or x16 slot and must be used in a PCIe 3.0 slot to achieve the 10Gbps peak; x1 or x2 slots are not supported.
A low-profile bracket is included, and the card installs into any PCIe x4 or wider slot on the motherboard.
