Sonnet Echo Express SE1 TB5 – Product Overview

Sonnet Echo Express SE1 T5 is a single-slot Thunderbolt 5 to PCIe card expansion system that connects a pro PCIe card to computers with Thunderbolt or USB4 ports.

Compact and rugged, the Echo SE I T5 supports a broad range of Thunderbolt-compatible, non-GPU PCIe cards and ships with a Thunderbolt 5 cable and ThunderLok connector lock.


Thunderbolt 5 Interface

The Echo SE I T5 uses a dual-port Thunderbolt 5 interface offering 80 Gbps of bi-directional data speed and up to 120 Gbps for higher display bandwidth.


PCIe Expansion And Bandwidth

The enclosure provides 6000 MB/s of bi-direction PCIe bandwidth to the installed card and features one x8 mechanical (x4 electrical) PCIe 4.0 slot.


Supported Cards

The Echo SE I T5 supports one half-length+ (maximum 7.75 inches long), single-width, full-height x8 PCIe card and one daughter card.


Power And Connectors

External connectors include two Thunderbolt ports and a 12V power port; an internal 6-pin Mini-Fit connector provides supplemental power to PCIe cards, and the secondary Thunderbolt port supplies 15W to connected peripherals.


Cooling And Enclosure

The system’s rugged aluminium housing contains a temperature-controlled, variable-speed fan for efficient, nearly noiseless cooling.


Compatibility And Operating Notes

Compatibility includes macOS 14+ Mac with Thunderbolt 5, Thunderbolt 4, Thunderbolt/USB4, or Thunderbolt 3 (Intel Macs with Thunderbolt 3 ports require macOS 15+); Windows 11 with Thunderbolt 5, Thunderbolt 4, or USB4; and Linux kernel 6.12, 6.18 (or newer) with Thunderbolt 5, Thunderbolt 4, or USB4 ports.


Physical Specifications

Dimensions are 3.0 x 11.13 x 5.75 in. (8.5 x 28.3 x 14.6 cm) and the weight is 2.5 lbs (1.13 kg); the unit operates from 0ºC to 35ºC (32ºF to 95ºF).


Package And Support

Package contents include the Echo SE I T5 Thunderbolt 5 Expansion System, universal power adapter, region-specific power cable, 6-pin to 6-pin auxiliary power cable, 0.8-meter Thunderbolt 5 cable, ThunderLok-A connector lock, and documentation; the product carries a 2-year warranty and lifetime technical support.
