Echo SE I T5 (1 PCIe slot + Space for a daughter card)
Part No. ECHO-EX-SE1-T5

Compact Footprint. Maximum Performance.
Echo SE I T5
1-slot Desktop Thunderbolt 5 to PCIe Card Expansion System for Computers with Thunderbolt or USB4 Ports
Connect One Full- or Half-length+ PCIe Card (Plus Daughter Card)
Laptop and mini computers with Thunderbolt 5 ports offer tremendous processing power, but don’t have the PCIe slots creative pros need for connecting adapter cards to add specialized ports and processing capabilities critical to their workflows. Sonnet offers the ideal solution to overcome this limitation with the Echo™ SE I T5 Thunderbolt™ 5 to PCIe card expansion system. This compact, single-slot system — compatible with Apple M series Macs, Intel Macs with Thunderbolt 3 ports, plus Windows and Linux computers with Thunderbolt 5 or 4 or USB4 ports — enables you to easily connect almost any Thunderbolt compatible, non-GPU PCIe card to your computer via an included Thunderbolt 5 cable.


Pro PCIe Card Expansion
Echo SE I T5 enables you to connect a pro PCIe card — such as video capture and playback; audio interface; SAS, SATA or Fibre Channel host bus adapter; multiport 10Gb or 25Gb Ethernet; or RAID controller — to add the ports and processors your computer lacks. Providing up to 6000 MB/s of bi-directional PCIe bandwidth to the installed card — twice that of Thunderbolt 4 or 3 — you’ll be able to extract even better performance with cards with ultra-high bandwidth requirements when connected to a computer with Thunderbolt 5 ports!

One PCIe 4.0 Slot and Space for a Daughter Card
Sonnet Echo SE I T5 features an x8 PCIe 4.0 slot, and supports a single- or double-width PCIe card. Double-width? Examples include pro video and audio cards like the Blackmagic Design DeckLink 8K Pro G2, which spans two card spaces, or main cards with connected daughter cards that use the neighboring space for additional ports.

Power To Spare
Echo SE I T5 includes an auxiliary PCIe power connector that enables you to use a card that requires extra power such as the AJA Kona 5, Blackmagic Decklink 4K Extreme12G and DeckLink 8K Pro G2, and Deltacast 12G/4C.

Supports Almost Any Thunderbolt-compatible, Non-GPU PCIe Card
Measuring just 3.4 inches wide by 11.2 inches long by 5.8 inches tall, the compact Echo SE I T5 supports cards at a maximum of 7.75 inches long, making it compatible with nearly all Thunderbolt-compatible PCIe 4.0, 3.0, 2.0, and 1.1 cards. Not sure if a card you own or are considering is compatible? We’ve put together a compatibility list that identifies cards that are Thunderbolt compatible and organized by fit and power compatibility with specific expansion systems.

Light. Rugged. Smart.
Echo SE I T5 system’s lightweight, rugged aluminum outer shell securely houses the installed PCIe card. Because it automatically powers on and off with your computer, there is no power switch on the enclosure, ensuring you don’t waste energy by forgetting to turn it off.

Nearly Noiseless Operation
Echo Express SE I T5 is engineered for ultra-quiet operation, making it ideal for noise-sensitive environments such as recording studios, broadcast facilities, edit bays, and shared office spaces. Its internal airflow path is optimized to allow the temperature-controlled, variable-speed fan to cool the installed card quietly and efficiently — even under peak load.

Secure Connection for High Performance – Thunderbolt 5 Cable and ThunderLok Included
Sonnet includes a Thunderbolt cable engineered to deliver Thunderbolt 5’s full bandwidth and power delivery performance. The cable is fully compatible with Thunderbolt 5, 4, and 3, and USB4 computers. A Sonnet ThunderLok Thunderbolt connector lock is also included to prevent accidental cable disconnections.

ThunderLok Advantage
Many Sonnet Thunderbolt products featuring Thunderbolt ports come equipped with threaded mounting holes to securely attach a Sonnet ThunderLok connector lock, preventing Thunderbolt cables from accidentally disconnecting.
Thunderbolt 5 – Tomorrow’s Performance. Today.
Echo SE I T5 is built with the features and quality you expect from a Sonnet expansion system, plus the Thunderbolt 5 interface you need for maximum performance. With 80 Gbps of bi-directional data speed — twice as fast as Thunderbolt 4 — and up to 120 Gbps for higher display bandwidth, you'll revolutionize your productivity.

More Than Just the Fastest External Interface Available
Echo SE I T5 features a dual-port, ultra-high speed Thunderbolt interface that delivers the PCIe bandwidth needed to support most cards at maximum performance. While one port is reserved for connecting your computer; the secondary port enables connection of additional Thunderbolt or USB peripheral devices.

• Connect Up to Five Additional Thunderbolt Devices
The secondary port supports Thunderbolt 5, 4, and 3 peripherals; you can even connect five additional self-powered Thunderbolt devices in a daisy chain.
• Supports 80 Gbps, 40 Gpbs, 20 Gbps, and 10 Gbps USB Peripheral
Connect an ultra-fast USB device to the second Thunderbolt port using the proper cable or adapter.
• Power Peripherals
15 watts is provided to bus-powered devices requiring extra power through the secondary Thunderbolt port.
• Supports Connecting One 8K Display
Maximize the utilization of one computer Thunderbolt port, connecting the highest resolution display supported by your computer.
