StarTech 2TBT3-PCIE-ENCLOSURE Thunderbolt 3 PCIe Expansion Chassis
Overview
The StarTech 2TBT3‑PCIE‑ENCLOSURE is a Thunderbolt 3 external PCIe expansion chassis designed to add dual PCIe 3.0 slots to Thunderbolt 3/4‑equipped laptops, desktops, or all‑in‑one systems. It empowers platforms without internal PCIe expansion to support cards for networking, capture, storage, or I/O acceleration. ([turn0search0][turn0search17])
It connects over a single Thunderbolt 3 cable at up to 40 Gbps and dynamically allocates 32 Gbps shared bandwidth between the two PCIe x16‑capable slots. The chassis supports half‑length single‑slot PCIe cards up to 8 in (20.3 cm), with active cooling provided by an integrated fan. The enclosure also offers native DisplayPort 1.4 and additional Thunderbolt 3 ports for displays or peripherals, enabling 4K/8K video support from the host. ([turn0search0][turn0search17])
Deployment is typical in engineering workstations, remote offices, or AV production where external expansion and GPU‑class devices are needed. It is not suitable as a standalone PCIe host or where native Thunderbolt support is unavailable. Driverless operation is supported in macOS and Windows; some installed cards may require card‑specific drivers. ([turn0search0][turn0search17])
