Sonnet Technologies today announced the launch of the eGPU Breakaway Box 750 and eGPU Breakaway Box 750ex, the newest and most powerful members of the company's award-winning family of Thunderbolt 3 to PCIe graphics processing (GPU) card expansion systems. Both systems support full-length, full-height, double-width GPU cards, and utilize large temperature-controlled fans that provide efficient and ultra-quiet cooling for the installed card. Sonnet designed these new expansion systems with the goal of offering users a future-proof purchase, equipping them with 750-watt power supplies capable of supporting the most power-hungry GPU cards available. The systems are nearly identical, except the eGPU Breakaway Box 750ex adds a built-in connection hub for USB devices and Ethernet connectivity.
