Thunderbolt 3 PCIe x16 enclosure

The StarTech TB31PCIEX16 is a Thunderbolt 3 expansion chassis that provides an external PCI Express 3.0 x16 slot and a DisplayPort connection. It connects to a host computer through two Thunderbolt 3 USB-C ports and supports up to 40 Gbps of bandwidth. The aluminium enclosure includes a 92 mm sleeve-bearing fan rated at 14.06 CFM and 24.55 dB, plus a universal power adapter and a Thunderbolt 3 cable in the box.

Suits laptops and compact PCs needing one

This enclosure serves users who want to add a single PCIe x16 card such as a capture, networking or storage controller to a Thunderbolt 3 laptop or small-form-factor system. It also adds a 4K DisplayPort output for an external monitor. Builders who need multiple PCIe slots, a larger card form factor, or an interface other than Thunderbolt 3 should consider a different chassis or an internal motherboard solution.

Deciding spec: Thunderbolt 3 40 Gbps link

The Thunderbolt 3 interface caps sustained PCIe throughput at 40 Gbps, which determines whether a given x16 card can run at its intended performance. Cards that require more bandwidth than the link provides will be limited by this connection.

商品問答

How do I decide whether the single x16 slot or the two Thunderbolt 3 ports suit my workflow?

The enclosure provides one PCI Express 3.0 x16 slot for a full-length card and two Thunderbolt 3 ports — one connects to the host, the other can daisy-chain another Thunderbolt device.

What does the 40 Gbps Thunderbolt 3 bandwidth deliver when a GPU or capture card is installed?

The Alpine Ridge DSL6540 controller links the x16 slot to the host at up to 40 Gbps, so high-throughput cards such as GPUs or 10 GbE adapters run near their PCIe 3.0 x4 potential.

How does the Thunderbolt 3 interface limit the PCIe lane width and display output?

Thunderbolt 3 caps the link to four PCIe 3.0 lanes and carries one 4K DisplayPort stream, so the x16 slot operates electrically as x4 while still accepting x16 cards.
