Product ID: BNDTBUSB3142
Connect your Thunderbolt™ 3 enabled computer to external USB 3.1 (Gen 2) devices using this Thunderbolt 3 to PCIe USB 3.1 adapter. Providing up to 10Gbps throughput, the adapter offers four USB 3.1 ports on two independent bus channels, an additional TB3 port, and a DisplayPort output. The adapter combines the StarTech.com USB 3.1 PCIe card (PEXUSB314A2V) and the TB3 chassis (TB31PCIEX16).
With two host controller chipsets, shared across two ports instead of four, this 4-port Thunderbolt 3 to USB 3.1 adapter dedicates up to 10Gbps for each set of two USB ports. It reduces performance bottlenecks and doubles your total available bandwidth to 20Gbps.
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.
Requiring only a Phillips type screwdriver, this Thunderbolt 3 to PCIe USB 3.1 adapter can be assembled and connected in minutes.
The TB31PCIEX16 and PEXUSB314A2V are backed by a StarTech.com 2-year warranty.

Special Notes / Requirements | System and Cable Requirements | Thunderbolt 3 equipped computer with a Thunderbolt 3 port. |
Note | USB power is limited to 900mA per port and is not recommended for charging external devices | |
The expansion chassis does not support video cards. | ||
This expansion chassis does not provide full power delivery but will provide 15W of power, resulting in a slow charge to some laptops, such as MacBook Pro. When the dock is connected to your host laptop, a charging icon may appear on your laptop's screen. This is only sufficient enough to charge your laptop in sleep state, and charging will require an extended time period. | ||
5K support can only be achieved using a Thunderbolt 3 5K monitor. DisplayPort 5K monitors will not work with this expansion chassis. | ||
A 4K-capable display is required to achieve 4K x 2K resolution (4K is also known as 4K x 2K). | ||
Certain monitors may be limited to 4K at 30Hz when connecting through DisplayPort. These monitors include the following models: Dell P2715Q, Viewsonic VX2475Smhl-4K, Philips 288P6LJEB, LG 31MU97C-B, Asus PB287Q (these models will need to be set to 4K at 30Hz). | ||
When connecting a display to one of the Thunderbolt 3 USB-C ports, a USB-C video adapter might be required depending on the input of your display. | ||
Secondary Thunderbolt 3 port can also be used to connect USB 3.1 (10Gbps) USB-Type C devices, such as USB 3.1 Hubs. Backwards compatible with USB 3.0 (USB 3.1 Gen 1), and USB 2.0. | ||

Live Chat (opens in new window)Thunderbolt 3 uses the USB-C connector, but not all host connections, cables, and devices with a USB-C connector support Thunderbolt 3. This means that a USB-C device is compatible with a Thunderbolt 3 host connection, but a Thunderbolt 3 device is not compatible with a USB-C host connection. Therefore, it is essential to know whether you have a USB-C or a Thunderbolt 3 host, cable, or device.
To determine if your component is a Thunderbolt 3 device, look for the Thunderbolt 3 symbol. USB-C devices do not include this symbol. For more information about USB-C, see the following FAQ: http://www.startech.com/faq/usb-c-port-capabilites
