Faster USB performance

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.

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 3.1 adapter can be assembled and connected in minutes.

 

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

Frequently Asked Questions

Before You Buy

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
