## Long description

The StarTech.com PEXUSB312C3 is a PCIe expansion card that adds two USB-C (10Gbps) ports to a desktop or server by occupying a PCI-Express slot (PCIe Gen3 x4). Powered by the ASMedia ASM3142 chipset, the card supports USB 3.2 Gen 2 (also known as USB 3.1 Gen 2) and is backward compatible with USB 3.2 Gen 1 (5Gbps) and USB 2.0 (480Mbps). It includes an optional SATA power connector for high-power devices and ships with both standard-profile and low-profile brackets for different system form factors.
