Sonnet Echo SE I T5 Thunderbolt 5 to Full-Height/Half-Length PCIe Card Expansion System

Elevate your creative and professional workflow with the Sonnet Echo SE I T5 Thunderbolt 5-to-PCIe Card Expansion System. Designed for maximum flexibility and performance, this compact desktop enclosure allows you to install a single full-height PCIe 4.0 x8 expansion card up to 7.75 inches long, seamlessly connecting it to your Thunderbolt 5-equipped computer for fast, efficient expansion.

Powered by the next-generation Thunderbolt 5 host interface, the Echo SE I T5 delivers transfer speeds of up to 80 Gb/s, offering exceptional bandwidth for demanding workflows. Whether you're using high-end video capture cards, 25G fibre network interfaces, SAS/SATA host bus adapters, or other PCIe-based hardware, this system ensures smooth, reliable performance.

Despite its small footprint, the enclosure is impressively versatile, accommodating single- or double-width cards. When using a single-slot card, you can even add a daughter card for additional connectivity. A built-in 6-pin auxiliary PCIe power connector provides extra power for high-performance cards, including the AJA Kona 5, Blackmagic DeckLink 4K Extreme 12G, and DeckLink 8K Pro G2.

The Echo SE I T5 also features a second Thunderbolt 5 port, allowing you to daisy-chain additional devices such as high-speed storage or an external display up to 8K resolution. This port provides up to 15W of power for connected peripherals, streamlining your setup without needing extra power supplies.

Engineered for professional environments, the enclosure combines a compact design with ultra-quiet operation. A temperature-controlled, variable-speed fan keeps your installed card cool while keeping noise to a minimum—ideal for studios, edit suites, and broadcast spaces. Its rugged aluminium housing ensures durability and long-term protection for your valuable hardware.

With smart power management, the system powers on and off automatically with your computer, eliminating the need for a physical power switch. Secure Thunderbolt connections are ensured by the included ThunderLok cable lock, which prevents accidental disconnections during critical tasks.

Compatible with Windows 11, macOS 14 or later, and Linux systems equipped with Thunderbolt 5, the Sonnet Echo SE I T5 is a powerful, future-proof solution for creatives, technicians, and professionals who need reliable PCIe expansion without compromising performance or workspace.
