Sonnet Express SE I Thunderbolt 5 Overview

Enhance your creative workflow with the Echo SE I T5 Thunderbolt 5 to PCIe Card Expansion System from Sonnet. This desktop enclosure can house a single full-height, PCIe 4.0 x8 expansion card measuring up to 7.75 inches long and connect it to your Thunderbolt 5 compatible computer.

Thunderbolt 5
With the Thunderbolt 5 host interface, you can transfer up to 80 Gb/s with compatible devices, providing plenty of bandwidth for video capture cards, 25G fiber network interfaces, SAS / SATA host bus adapters, and other expansion cards.
Small and Versatile
The ECHO EXP SE I T5 has room for a single- or double-width PCIe 4.0 x8 expansion card. Installing a single slot card allows you to add a daughter card for additional ports.
Power to Spare
A 6-pin auxiliary PCIe power connector provides extra power for expansion cards such as the AJA Kona 5, Blackmagic Decklink 4K Extreme12G, and DeckLink 8K Pro G2.
Connect Additional Devices
Use the second Thunderbolt 5 port to daisy chain devices such as storage drives and an up to 8K display. The port provides up to 15W power to connected peripherals.
Compact Design
The Echo SE I T5 features a small footprint but is large enough to ensure maximum performance.
Extremely Quiet
A temperature-controlled, variable-speed fan automatically cools the installed card. Ultra-quiet operation makes this enclosure ideal for environments such as recording studios, broadcast facilities, and edit bays.
Rugged Design
The durable aluminum housing protects your installed card.
Smart Power Management
The system powers on and off automatically with the computer. No power switch is required.
Secure Connections
The included Thunderbolt 5 cable may be secured with the ThunderLok connector lock to avoid accidental disconnections.
Compatibility
Connect the Echo SE I T5 to your Thunderbolt 5 compatible Windows 11, macOS 14 or later, or Linux based computer system.
