Connect Three Full-Length PCIe Cards to Any Mac with a Thunderbolt 3 Port
 

PCIe Card and Notebook Icons

For pros working in the creative fields, a computer’s processing power alone is not enough to get the job done. A prime example is the latest MacBook Pro®, which, while offering great performance, lacks the PCIe expansion slots necessary to support specialty cards that connect pro video and audio inputs, transcode data, and connect to high-speed storage and networks. Instead of slots, these computers include ultra high-performance Thunderbolt™ 3 ports to support peripherals. Sonnet’s Echo™ Express III-R (Thunderbolt 3 Edition) leverages the Thunderbolt 3 ports’ PCIe data to connect PCIe expansion slots outside of a computer. This desktop Thunderbolt-to-PCIe card expansion chassis enables you to connect three professional PCIe cards—including video capture, audio interface, SAS or SATA HBA, 16Gb or 8Gb Fibre Channel, 10 Gigabit Ethernet, and RAID controllers—at the same time to any Mac® or Windows®(1)computer with a Thunderbolt 3 port.

The Echo Express III-R (Thunderbolt 3 Edition) features a 40Gbps Thunderbolt 3 interface, which offers double the PCIe bandwidth and connectivity of Thunderbolt 2, and yields up to 2750 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(2)(3). With the ability to handle multiple demanding, highest performance PCIe cards, support for connecting two 4K displays @ 60Hz or one 5K display @ 60Hz(4), and support for a vast array of Thunderbolt(5) and USB(6) devices, Thunderbolt 3 is a leap forward in every way.

300W Power, 75 Aux Power, and Enviro-Friendly Icons

Echo Express III-R TB3 (Inside View)Three PCIe 3.0 Slots, No Compromise

Sonnet’s Echo Express III-R supports three full-size PCIe cards, up to 12.28 inches (full-length) long. The III-R integrates a universal 300W power supply and includes a 75W PCIe power connector for cards that require supplementary power, such as the RED® ROCKET-X.

Even with all that power, the III-R is enviro-friendly; it automatically powers on or off whenever the connected computer powers on or wakes, or powers off or sleeps, respectively.

40Gbps Thunderbolt 3 —
The USB C That Does It All

The Echo Express III-R (Thunderbolt 3 Edition) includes two Thunderbolt 3 ports; the first is used for connection to your computer, while the second supports daisy chaining of up to five additional Thunderbolt peripheral devices to a single port on your computer(5). The III-R includes 10Gbps USB 3.1 Gen 2 support, meaning you can connect a USB device to the second port using the proper cable or adapter. The III-R also provides full support for connecting two 4K displays @ 60Hz or one 5K display @ 60Hz(4). For connected devices requiring extra power, 15 watts is provided to connected bus-powered devices.

All-Around Smart Design

Aluminum and Auto Power IconsThe Echo Express III-R's enclosure is formed of heavy-duty steel to provide secure mounting for the inner assembly and protection for the PCIe cards installed inside, and to support maximum airflow for cooling, regardless of where you install it in a rack.

Its two large, slow-spinning fans, enhanced with computer-modeled airflow management, ensure that even hot-running cards remain reliably cool without the need to install an extra PCIe blower card that would prevent the use of one of the three slots. Because the fans automatically speed up and slow down as needed, you don’t have to guess which speed setting to select, and there’s no need for tools to change settings. There is no power switch on the chassis, nor is one needed, because the III-R automatically powers on and off with your computer.


The III-R’s adjustable rackmount extension rails enable the chassis to be installed securely in a variety of racks from 16 to 24 inches deep (optional, extra-long extension rails that support installation in racks up to 32.5" deep are also available). Captive thumbscrews secure the inner assembly, enabling you to secure, release, and slide it out without the need of tools. Using an optional Mobile Rack Device Mounting Kit, you can install two 5.25-inch mobile rack devices (sold separately) in the III-R's enclosure without taking up additional rack space.

Fan with Cool AirQuiet Operator

The Echo Express III-R is remarkably quiet—comfortably used in noise-sensitive environments, it is one of the quietest Echo systems. The natural convection of warm air through the PCIe cards is assisted by ultra-quiet, temperature-controlled, variable-speed fans, and vented out of the chassis with reduced air velocity and turbulence, resulting in little fan noise.

Every Thunderbolt 3 Compatible
PCIe Card Supported

The Echo Express III-R (Thunderbolt 3 Edition) supports three single-width, full-length PCIe cards, or one double-width, full-length card plus one single-width card, enabling it to support every Thunderbolt 3- and macOS-compatible PCIe 1.1, PCIe 2.0, and PCIe 3.0 card available.

x8 and x16 PCIe Cards

Echo Express III-R features two x8 plus one x16 PCIe slots for versatile card support
 

Designed for BNC Connector Cables

Echo Express III-R’s back panel has two BNC connector mounting holes, enabling the use of a RED ROCKET card without the need to install the BNC connector bracket that would normally occupy a valuable PCIe slot.

Technical Notes

  1. Windows computers require the latest firmware (BIOS) and Thunderbolt drivers to support this product. Check with your computer manufacturer for update information. Not all Mac-compatible PCIe cards are also compatible with Windows. See the PCIe Card Thunderbolt Compatibility Chart for details.
  2. While the Echo Express III-R - Thunderbolt 3 Edition features a 40Gbps Thunderbolt 3 interface, some computers equipped with Thunderbolt 3 use an implementation of Thunderbolt 3 technology that limits PCIe performance to 20Gbps. The MacBook Pro (13-inch, Late 2016, Four Thunderbolt 3 Ports) has this limitation in the two right-hand Thunderbolt 3 ports, while offering full performance from the left-hand ports.
  3. Full performance requires the use of the included Thunderbolt 3 (40Gbps) cable, or other Thunderbolt 3 (40Gbps) cables; look for the Thunderbolt icon AND the number 3 on the connector housings to identify these cables.
  4. One 4K monitor directly supported. Two 4K monitors requires either a 4K monitor with multi-stream transport support (DP out), or a Thunderbolt 3 to Dual DisplayPort adapter. 5K monitor requires a Thunderbolt 3 to Dual DisplayPort adapter. All Thunderbolt 3 Macs support two 4K monitors. Most Thunderbolt PCs support two 4K monitors.
  5. Second Thunderbolt 3 port supports Thunderbolt and Thunderbolt 2 peripheral devices on Macs used with the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter, sold separately.
  6. Second Thunderbolt 3 port supports USB 3.1 Gen 1 (5Gb) or Gen 2 (10Gb) devices when connected with proper cable or adapter (sold separately).
  7. PCIe cards and Mobile Rack Device Mounting Kit sold separately.
  8. Power supply will operate as low as 90VAC, with linear power deration from 300W @ 115VAC to 240W @ 90VAC.
  9. Sonnet 1-meter Thunderbolt 3 (40Gbps) cable is not compatible with ThunderLok 3.
  10. Official certification pending.
