Connect three half-length, full-height PCIe cards to systems with a Thunderbolt 5 port using the Echo SE III Thunderbolt 5 Expansion Chassis for PCIe Cards from Sonnet. The Echo SE III is useful for expanding the connectivity of systems like the MacBook Pro, which does not have the PCIe slots needed for pros working in creative fields. Instead, the Echo SE III connects to Thunderbolt 5 hosts to leverage this connectivity via PCIe expansion slots that are outside of the computer. This chassis has two PCIe 3.0 x8/x8 slots and one PCIe 3.0 x8/x4 slot. These three slots can support one half-length+ (up to 7.75" long), double-width, full-height PCIe x8 card, plus one single-width card, or three half-length+, full-height PCIe x8 cards for video capture, audio DSP, 6Gb or 12Gb SAS or SATA host bus adapters, 10Gb, 25Gb, or 40Gb Ethernet cards, RAID controllers, and more.
The Echo SE III features two 80 Gb/s Thunderbolt5 ports, one of which is used to connect to your host Windows, Mac, or Linux system and provides up to 100W of power. The second Thunderbolt 5 port, which provides up to 15W of power, can be used to daisy-chain up to 5 additional Thunderbolt devices, plus one 5K display at 60 Hz, two 4K displays at 60 Hz, or one USB 3.0 device. For power hungry cards, there is an additional internal 6-pin PCIe power connector.
Cool operations are driven by dual internal Noctua cooling fans. A Thunderbolt 5 cable, a ThunderLok 3 retainer clip, a universal power adapter, and a power cord are included with this chassis. Protection is provided by a limited 2-year warranty and free lifetime technical support.
Please note that the Echo SE III does not support GPUs. Also, two 4K displays requires a monitor with multi-stream transport support (DP out) or a Thunderbolt 5 to Dual DisplayPort Adapter.

Sonnet SE III Overview
General Features
Nearly Every Thunderbolt-Compatible, Non-GPU PCIe Card Supported
Similar in size to the Echo Express SE IIIe (Thunderbolt 3 edition), the Echo SE III is still large enough to support nearly every Thunderbolt 5 compatible card available. With its three x8 slots, the SE III supports PCIe 3.0, PCIe 2.0, and PCIe 1.1 cards up to 7.75" long. Do you have a card in mind but aren't sure it's compatible? Check Sonnet's PCIe Card Thunderbolt Compatibility Chart. There you'll find cards identified as conforming to Thunderbolt technology requirements, and they are organized by fit and power compatibility with specific expansion system.
Design Smarts: Aluminum Enclosure, Auto Power On/Off
The inside of the Echo SE III is wrapped in a rugged, yet lightweight aluminum outer shell, resulting in a lightweight system small enough to carry in your backpack, yet durable enough to protect the installed PCIe cards securely. Since Echo products automatically power on and off with your computer, there is no power switch on the chassis, ensuring you don't waste energy by forgetting to turn it off.
Three PCIe 3.0 Slots for Demanding Professional Needs
The Echo Express SE IIIe's PCIe 3.0 x8 slots support three half-length+, full-height, single-width PCIe cards, or one single-width card plus one double-width card.
Double Width
Some specialty cards, such as RME's HDSPe MADI FX, Blackmagic Design's DeckLink 4K Extreme, and the Lynx AES16e 50, include a daughter card that mates with and provides additional external connections to the main card.
Power to Spare
The Echo Express SE IIIe includes an auxiliary PCIe power connector, enabling you to install a card requiring extra power, such as the AJA Kona 5 or Blackmagic DeckLink 4K Extreme 12G, and Bluefish444's Epoch and KRONOS SDI cards.
Quiet Please
The Echo SE III is designed to be quiet so that it can be comfortably used in noise-sensitive environments. Its enclosure is ventilated front and back to facilitate airflow over the cards by dual large, quiet, temperature-controlled Noctua fans, rated at 17 dBA. The fan automatically speeds up and slows down smoothly as needed, so there's no guesswork in deciding which fan speed to select.
Thunderbolt 5 Cable and ThunderLok 3 Included
Sonnet includes a 2.6' 80 Gb/s Thunderbolt 5 cable that, unlike some other cables, transfers data at Thunderbolt 3's full 3400 MB/s bandwidth and supports up to 100W of Power Delivery (PD). Sonnet also provides a ThunderLok 3 Thunderbolt connector retainer clip that prevents accidental cable disconnections. Just slide it over one end of the cable and then plug in the connector and secure it to the chassis by turning a thumbscrew. Because of its unique design, the ThunderLok remains on the cable so it won't get lost when not in use.
Fast External Interface
The Echo SE III features a 80 Gb/s Thunderbolt 3 interface, which offers double the PCIe bandwidth and connectivity of Thunderbolt 3, and yields up to 3400 MB/s of bandwidth, enabling it to support 4K video capture and processing cards at high frame rates, and 16Gb FC cards and dual-port 10GbE cards at full performance.
Thunderbolt 5 / USB Type-C
The Echo SE III includes two Thunderbolt 5 ports. The first connects it to your computer, while the second supports the daisy-chaining of up to five additional Thunderbolt peripheral devices to a single port on your computer. The Echo SE III also includes 10 Gb/s USB 3.1 Gen 2 support, meaning you can connect a USB device to the second port using the proper cable or adapter. For connected peripherals requiring extra power, 15W is provided to connected bus-powered devices. With the ability to handle multiple demanding, high-performance PCIe cards, support for connecting two 4K displays at 60 Hz or one 5K display at 60 Hz, and support for a vast array of Thunderbolt and USB devices, Thunderbolt 5 is a leap forward.
Fast Performance
With 3400 MB/s of bandwidth, connect your computer to one Thunderbolt 5 port on the Echo Express SE IIIe, then use the second Thunderbolt 5 port to daisy chain up to five additional Thunderbolt devices, plus two 4K display, one 5K display, or one USB 3.0 device.
