Sonnet Echo III T5 Module
Pro ExpansionDiscover the Sonnet Echo III T5 Module, a professional 3-slot Thunderbolt 5 PCIe card expansion module that connects up to three full-height, full-length non-GPU PCIe cards to Thunderbolt 5, Thunderbolt 4, or USB4-equipped Mac, Windows, and Linux computers. Featuring one PCIe 3.1 x16 slot and two x8 slots, the Echo III T5 Module delivers up to 3,400 MB/s of aggregate bi-directional PCIe bandwidth when connected to a Thunderbolt 5 port, making it a powerful solution for video capture and streaming, audio DSP including Avid Pro Tools | HDX, high-speed Ethernet, SSD storage, and SAS host bus adapters. Its integrated 400W power supply supports power-hungry cards, while dual temperature-controlled Noctua fans rated at just 17 dBA help maintain quiet, reliable operation. With two 80 Gbps Thunderbolt 5 ports, the module also lets you connect an additional Thunderbolt or USB peripheral, making it an ideal PCIe expansion solution for creative professionals, broadcasters, and high-performance workstation users.
Build a Powerful Desktop Creative Studio
Connect Three Full-length Pro PCIe CardsToday’s laptop and mini desktop computers with ultra-high-performance Thunderbolt™ 5 ports offer tremendous onboard processing power, but lack the PCIe slots needed to connect adapter cards that provide specialized ports and processing capabilities essential to professional audio and video production workflows. Echo III T5 Module provides the slots you need. Using the included Thunderbolt 5 cable, this professional expansion system connects up to three PCIe cards (up to 12.28 inches long) to the latest Macs, Windows PCs, and Linux computers. Add nearly any compatible (non-GPU) PCIe card to create the purpose-built setup your workflow demands.
Three PCIe 3.1 Slots
Comprehensive PCIe Card SupportEcho III T5 Module features one x16 and two x8 PCIe 3.1 slots. When connected to a Thunderbolt 5 computer port, it provides them 3400 MB/s aggregate, bi-directional PCIe bandwidth. This system supports single-and double-width, PCIe 4.0, 3.1, 2.0, and 1.1 cards including video capture, streaming and transcoding; audio DSP; 25Gb Ethernet; SSD storage; SAS host bus adapter; and other specialty types.

Made for Low-Noise Environments
Dual Noctua FansEcho III T5 Module is built for noise-sensitive environments, delivering ultra-quiet performance with dual Noctua fans that operate below the recommended 20 dBA limit for recording and broadcast studios. The temperature-controlled fans’ speeds adjust smoothly as needed, while optimized airflow efficiently cools installed cards, keeping the system quiet under demanding workloads.
Light, Yet Rugged
Built for the Work AheadThe Echo III T5 Module uses a lightweight, rugged aluminum outer shell to securely house the inner assembly that holds the installed PCIe cards and the integrated power supply.
Secure Connections for High Performance
Thunderbolt Cable & ThunderLok IncludedSonnet 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.
