Thunderbolt 3 PCIe enclosure

The StarTech BNDTB1394B3 is a Thunderbolt 3 external chassis that adds a full-length PCI Express x16 slot to a compatible computer. It ships with a FireWire adapter card pre-installed, providing one FireWire 400 port and two FireWire 800 ports for legacy peripherals. A DisplayPort output is also included for video pass-through. The unit is built from aluminum and steel and includes a 92 mm sleeve-bearing fan for active cooling.

Build integration: power, slots and video

The enclosure requires its included 65 W AC adapter, which accepts 100 to 240 V AC input and delivers 12 V DC at 5.417 A to the internal LP4 power connector. Two Thunderbolt 3 USB-C ports allow daisy-chaining additional Thunderbolt devices or connecting a DisplayPort monitor. A single full-height, full-length PCIe x16 card can be installed and swapped using only a screwdriver, freeing the host system from internal slot constraints.

Suits FireWire users; not for internal-only builds

This chassis suits professionals who must keep FireWire audio interfaces, cameras or storage devices working on modern Thunderbolt 3 computers without replacing them. It also serves anyone needing an external PCIe slot for specialised expansion cards. Builders who only need internal expansion, or who lack a Thunderbolt 3 port on their host, should look at other solutions.

Questions about this item

What is the sustained power limit of the included 65W AC adapter when the enclosure runs all day?

The external AC adapter delivers 12 V at 5.417 A for a continuous 65 W budget that powers the PCIe card, the 92 mm sleeve-bearing fan and the FireWire ports.

How loud and how hot does the 92 mm sleeve-bearing fan get during continuous operation?

The single 92 mm sleeve-bearing fan draws cooling air through the aluminium-and-steel chassis; under full load the 65 W supply and the installed card determine the thermal output and acoustic level.

Which Thunderbolt 3 host and cable must I already own for this enclosure to function?

A Thunderbolt 3 equipped computer with a Thunderbolt 3 port and a compatible Thunderbolt 3 USB-C cable are required to activate the two downstream Thunderbolt 3 ports, the DisplayPort output and the FireWire 400 and 800 connectors.
