StarTech 2TBT3-PCIE-ENCLOSURE PCIe Expansion Enclosure, 2-Slot, Thunderbolt 3, DisplayPort 1.4, Black

The StarTech Thunderbolt 3 PCIe Expansion Chassis provides a method for connecting two PCI Express cards to a host computer via a Thunderbolt 3 or Thunderbolt 4 port. Constructed from durable aluminum, the external enclosure measures 281 by 84 by 142 millimeters and houses two internal PCIe 3.0 x16 slots. This hardware allows laptops and compact desktop systems to utilize specialized expansion cards that would otherwise require a traditional desktop motherboard. An integrated 60 mm fan provides active cooling to maintain stable operating temperatures for the internal components during heavy workloads.

This expansion chassis utilizes a 40 Gbit/s Thunderbolt 3 interface to ensure high-bandwidth data transfer between the system and the installed PCIe cards. It includes a dedicated DisplayPort 1.4 output, which supports a single 8K monitor or dual 4K display configurations for multi-screen workstation environments. The unit draws power from an included external 12V adapter and comes with a one-meter Thunderbolt cable for direct connection to the host. It offers broad system compatibility across Windows, macOS, and Linux platforms, provided the installed cards have the necessary driver support.
