    Thunderbolt 3 to PCIe USB 3.1 Adapter - Chassis + Card

At a Glance

    • Transfer files and access USB 3.2 Gen 2 devices faster, with up to 10Gbps throughput
    • Create an efficient work station with extra displays using the DisplayPort output and additional Thunderbolt 3 port
    • Upgrade your peripherals without having to upgrade your chassis by just switching out your PCIe card
    • Assemble and install easily with just a screwdriver


    Connect your Thunderbolt™ 3 enabled computer to external USB 3.2 Gen 2 devices using this Thunderbolt 3 to PCIe USB 3.2 Gen 2 adapter. Providing up to 10Gbps throughput, the adapter offers four USB 3.2 Gen 2 ports on two independent bus channels, an additional TB3 port, and a DisplayPort output. The adapter combines the StarTech.com USB 3.2 Gen 2 PCIe card (PEXUSB314A2V) and the TB3 chassis (TB31PCIEX16).

    Faster USB performance

    With two host controller chipsets, shared across two ports instead of four, this 4-port Thunderbolt 3 to USB 3.2 Gen 2 adapter dedicates up to 10Gbps for each set of two USB ports. It reduces performance bottlenecks and doubles your total available bandwidth to 20Gbps.

    Increase productivity with Thunderbolt 3

    Thunderbolt 3 is the fastest connection available. By avoiding performance bottlenecks, you can accomplish more in the same amount of time. With 40Gbps of throughput and support for other high-performance PCIe cards, you can swap the card in and out, to add the peripherals you need connected to a Thunderbolt 3 desktop or laptop computer.

    Install and assemble with ease

    Requiring only a Phillips type screwdriver, this Thunderbolt 3 to PCIe USB 3.2 Gen 2 adapter can be assembled and connected in minutes.

    The TB31PCIEX16 and PEXUSB314A2V are backed by a StarTech.com 2-year warranty.
