The eGFX Breakaway Box 550 provides a single slot for connecting any size Thunderbolt-compatible GPU card, and features enough room for even high-performance water cooler cards. The unit is equipped with a single 40Gbps Thunderbolt 3 port that enables data transfers up to 2,750 MB/s, and supports Thunderbolt-compatible cards with popular GPU chipsets — such as AMD Radeon and Radeon Pro; NVIDIA GeForce, TITAN XP, and Quadro cards. 

In addition, the Breakaway Box 550 includes two eight-pin auxiliary power connectors and provides 87 watts of upstream power (power delivery), useful for powering and charging a connected notebook computer. It has a manufacturer’s suggested retail price of $349.
