Sonnet Echo Express SE IIIe Thunderbolt 3 Expansion Chassis for PCIe Cards



The Sonnet Echo™ Express SE IIIe is a sleek, desktop Thunderbolt™ 3 to PCIe card expansion system, designed to connect up to three professional PCIe cards simultaneously to any computer with Thunderbolt 3 ports.

Compact in design, the Echo Express SE IIIe offers three PCIe expansion slots in a desktop-sized enclosure. While it’s more compact than the Echo Express III-D (Thunderbolt 3 Edition), it’s sufficiently sized to accommodate almost all Thunderbolt 3 compatible, non-GPU PCIe cards. The unit features three x8 slots, compatible with PCIe 3.0, 2.0, and 1.1 cards, supporting cards up to 7.75 inches in length.

The Echo Express SE IIIe is specifically built to house such cards with ease. For those needing additional power, it includes an auxiliary PCIe power connector. This feature allows the installation of power-hungry cards like the AJA® Kona® 5 or the Blackmagic DeckLink 4K Extreme 12G, ensuring that you have the power and flexibility for a wide range of professional applications.
