This PCIe expansion card adds two USB-C ports to a desktop computer, enabling high-speed data transfer at up to 10Gbps. It is ideal for users who need to connect high-performance external storage devices, such as NVMe drives and SSDs, or other USB 3.2 Gen 2 peripherals. The card uses the ASMedia ASM3142 chipset and supports USB Attached SCSI Protocol (UASP) for optimized performance. It provides up to 15W of power per port but does not support video output or USB Power Delivery through the USB-C ports.
The card installs into a PCIe 3.0 x4 slot and is compatible with full or low-profile form factors, with a bracket included for both options. It works with Windows, macOS, and Linux operating systems, with automatic driver installation available for Windows 8 and newer versions. The card is backward compatible with USB 3.0 and USB 2.0 devices, allowing users to connect older peripherals using USB-C cables or adapters. It is designed for IT professionals and includes technical support for two years.
The card is suitable for tasks that require high data throughput, such as video editing, file backups, and data recovery using external storage solutions. It does not support DP Alt Mode for video output or USB Power Delivery, so it is not suitable for powering devices that require higher wattage or video transmission over USB-C. The card includes a SATA power connector for optional use with high-power devices but relies on the system's PCIe bus for performance.
The product comes with a low-profile bracket, a quick start guide, and the PCIe card itself. It is backed by a two-year warranty and free lifetime technical support. The card is designed to be installed in desktop PCs or servers with available PCIe slots and requires no additional software beyond the included drivers.
