Product information

Description

Add an external PCIe (PCI Express 3.0) x16 slot and a DisplayPort connection to your Thunderbolt 3 equipped MacBook or laptop with the PCIe Expansion Chassis StarTech TB31PCIEX16. This Thunderbolt 3 chassis connects via an external Thunderbolt 3 port to provide a full-length PCIe x16 slot for installing expansion cards, plus a DisplayPort output for an additional monitor. It supports Thunderbolt 3 daisy chaining to integrate additional devices into your workstation.

Advantages

The StarTech TB31PCIEX16 enables desktop-class PCIe expansion for Thunderbolt 3 laptops and computers, supporting PCIe 3.0 performance over a 40 Gbps Thunderbolt 3 connection. It accepts a wide range of PCI Express cards such as USB, SSD, network, eSATA, FireWire and video capture cards, and includes a DisplayPort output and a second Thunderbolt 3 (USB-C) port for connecting extra displays or chaining other Thunderbolt/USB/DisplayPort devices. The unit is compact, bus-powered with external power supply compatibility, and includes active cooling with a single fan.

Suitable for

Adding PCIe USB 3.x/USB-C expansion to a Thunderbolt 3 laptop
Connecting external SSD or RAID controllers for fast file access
Installing network or capture cards for production workflows
Driving an additional monitor via DisplayPort or USB-C video adapter

How to use

Connect the TB31PCIEX16 to a Thunderbolt 3 port on your laptop or desktop using a Thunderbolt 3 cable. Install a compatible PCIe card into the internal PCIe x16 slot following the card manufacturer's installation instructions. Use the DisplayPort output to attach an external monitor, or connect a monitor via the second Thunderbolt 3 (USB-C) port using an appropriate video adapter if required. If you need additional devices, use the second Thunderbolt 3 port to daisy chain Thunderbolt or USB accessories. Ensure the chassis is connected to mains power before powering the system.
