The Thunderbolt 3 eGXF box is a low cost expansion chassis designed to house an external graphics card. Connected to the computer via Thunderbolt 3, the additional GPU power instantly upgrades a regular laptop or a mini PC and makes it possible to do things that would normally require a high-end workstation or gaming computer. For video editors and colorists, the dedicated GPU reduces the time it takes to render the footage, a computer that was not powerful enough for a VR headset is now potentially VR ready and for those that like to play games, these can now run at much higher frame rates than before. Supports standard and large sized PCIe Gen3 x4 cards The PCIe (x16) slot accepts full-length, full-height, double-width cards with enough space available inside the enclosure for both standard and large sized graphics cards. The four PCIe Gen3 lanes and the Thunderbolt 3 interface are capable of transfer rates up to 40Gbps, providing enough bandwidth even for the most demanding PCIe cards. 400W SFX PSU The built-in power supply provides enough power for the AKiTiO Node (~10W) as well as for graphics cards. If the standard 75W through the PCIe slot is insufficient, two extra pairs of 8-pin (6+2 pin) power connectors are available inside the AKiTiO Node that can be connected to the GPU, providing a total of about 390W. Thunderbolt? 3 Thunderbolt 3 brings Thunderbolt to USB-C at speeds up to 40 Gbps, creating one compact port that does it all ? delivering the fastest, most versatile connection to any dock, display, or data device. In combination with the AKiTiO Node, this makes it possible to instantly upgrade your regular laptop or Mini-PC and achieve a performance that usually requires high-end workstations or specialized gaming computers.
