2-port USB-C 10Gb PCIE X1 Expansion Card: Even though the ASM 3142 Chip supports PCIE 3.0 X2 speeds, because of the PCIE X1 design, the upstream bandwidth is only PCIE 3.0 X1=8Gbps.
Advantage: It uses the free motherboard PCIE X1 slot instead of occupying the X4/X8/X16 slot. Disadvantage: 2 x USB-C ports share 8Gbps speed, can not reach 10Gbps simultaneously.
High-Power Support: Separate power management allows each port to handle high-power devices (up to 5V2A), ideal for industrial cameras, VR systems, and USB 3.2 NVME enclosures.
Wide Compatibility: Works with Windows 11/10/8, Mac OS, and Linux. Note: Requires driver for Windows 7, not compatible with Windows XP.
Flexible Installation: Includes regular & low-profile brackets for all computer cases. Enjoy lifetime technical support for any issues.
