StarTech Thunderbolt 3 PCIe External Enclosure

Extend laptop and desktop systems with the PCIe capacity they need for demanding workflows. The StarTech Thunderbolt 3 PCIe External Enclosure gives IT teams and technical users a practical way to add external expansion without replacing the host system. It is designed for Thunderbolt 3 and Thunderbolt 4 environments, making it a strong fit for mobile workstations, compact desktops, and field-ready setups that need specialized I/O. With dual external PCIe 3.0 x16 slots, the enclosure supports cards used for video capture, fiber, Ethernet, and FireWire applications, including single-width cards up to 8 inches long. Each slot supports up to 2,700 MBps, and the chassis delivers 25 W per card, helping maintain stable operation for supported expansion hardware. Dual internal SATA power ports add flexibility for connected devices, while the included 3.3 ft Thunderbolt 3 cable simplifies deployment. The enclosure also supports a second display through DisplayPort 1.4 and Thunderbolt 3 ports, with 8K and 4K support for high-resolution workflows. Driverless operation across macOS, Windows, and Linux reduces setup friction, and daisy-chain compatibility helps preserve port availability in multi-device environments. For teams that need external PCIe expansion with professional-grade connectivity, this enclosure delivers a focused, purpose-built solution.
