A compact desktop Thunderbolt™ 3 to PCIe Card Expansion System that enables you to connect three professional PCIe cards—including video capture, audio interface, SAS or SATA HBA, 16Gb or 8Gb Fibre Channel, 10 Gigabit Ethernet, and RAID controllers—at the same time to any computer with Thunderbolt 3 ports.

The Sonnet Echo Express SE III connects three PCIe cards to any computer with Thunderbolt 3 ports—Use multiple high-performance PCIe cards at the same time.

  • Temperature-controlled Fan - Automatically operates slower and quieter with cooler cards; provides better cooling for hotter cards

  • Power for Peripherals - Provides up to 15W of power to connected peripherals
