Echo Express SE IIIe (3 PCIe slots + Compact design)

Part No. ECHO-EX-SE3E-T3. Connect Three Full-height, Half-length+ PCIe Cards to Computers with Thunderbolt 3 or Thunderbolt 4 Ports Although thin Mac®, Windows® 10, and Linux® computers with Thunderbolt™ ports offer processing power to spare, for many users (such as pros in the creative fields) onboard processing power alone is not enough. Sonnet’s Echo™ Express SE IIIe is a compact, desktop Thunderbolt™ to PCIe card expansion system that enables you to connect three professional PCIe cards at the same time to any computer with Thunderbolt 3 or Thunderbolt 4 ports. Echo Express SE IIIe - Desktop Expansion with Auxiliary Power Connector Echo Express SE IIIe provides three PCIe card expansion slots in a compact desktop enclosure. Smaller than the 3-slot Echo III Desktop, the Echo Express SE IIIe is still large enough to support nearly every Thunderbolt 3 compatible, non-GPU PCIe card available. With its three x8 slots, the SE IIIe supports PCIe 3.0, PCIe 2.0, and PCIe 1.1 cards up to 7.
