Technical Notes

1. eGFX Breakaway Box models support up to a standard full-height, full-length, double-width card. Cards with three power connectors are not supported.
2. While the eGFX Breakaway box features a 40Gbps Thunderbolt 3 interface, some computers equipped with Thunderbolt 3 use an x2 PCIe lane implementation of Thunderbolt 3 technology that limits PCIe performance to 20Gbps. Find more computer information here. Full performance also requires the use of the included Thunderbolt 3 (40Gbps) cable, or other Thunderbolt 3 (40Gbps) cables; look for the Thunderbolt icon AND the number 3 on the connector housings to identify these cables.
3. Choose eGFX Breakaway Box model that supports the power requirement of the chosen card.
