Because the card offers USB Type-C™ ports, you can rest assured your computer is compatible with the growing popularity of USB-C peripherals.
Work faster, with USB 3.1 performance By adding 10Gbps USB ports to your computer, you can harness the speed of USB 3.1 Gen 2. You can access peripherals at twice the speed of traditional USB 3.0 devices. (USB 3.0 is also known as USB 3.1 Gen 1.) The card delivers faster file transfer rates, so you can get more work done in less time.
With higher data throughput, this PCI Express USB 3.1 card is a necessity for external hard drives, hard drive enclosures, and many other USB 3.1 peripherals. Plus, the USB card integrates a SATA power connector to support high-powered devices, making it ideal for use with large external storage solutions.
Help future proof your computer, with USB-C Because it offers two USB-C ports, this innovative card enables you to connect the growing number of USB Type-C devices today, or in the near future.
USB-C connectors are small, reversible, and easy-to-use. You can reduce frustration and the risk of damage to your ports by connecting the plug with either side facing up, making insertions easier than past USB generations.
The card is backward compatible with USB 3.0 (5Gbps) and USB 2.0 (480mbps) devices. You can add the card now in preparation for future devices, while still connecting your existing USB peripherals using a variety of USB-C cables and adapters.
Easy to install in different form factors The PCIe USB-C card comes equipped with a full-profile bracket, but also includes a half-height or low-profile bracket, making it easy to install in full or small form-factor desktops or servers. And, the card offers hassle-free installation, with no additional software or drivers required in many natively supported operating systems.
The PEXUSB312C is backed by a StarTech.com 2-year warranty and free lifetime technical support.

Special Notes / Requirements
The card's USB-C ports are standard data throughput port. They do not support DP Alt Mode or USB Power Delivery.
The maximum throughput of this card is limited by the bus interface. PCI Express Gen 1.0 max throughput is 2.5Gbps. PCI Express Gen 2.0 max throughput is 5Gbps. PCI Express Gen 3.0 max throughput is 10Gbps.
The available bandwidth (10Gbps) is shared equally between the two ports.
System and Cable Requirements
PCI Express enabled computer or server with a PCI Express x4 slot or higher (x8, x16)
