Sonnet Echo Express SEL Thunderbolt 3 PCIe Expansion - Low-Profile

About: Sonnet Echo Express SEL Thunderbolt 3 PCIe Expansion - Low-Profile

NOTE: Only compatible with low profile cards

Shopping for a new computer? Small and thin is in—the latest ultra-light notebooks, small form factor, and all-in-one desktops are slender marvels of engineering. But, thinness comes with a cost—there’s nowhere to install PCIe cards that provide additional connectivity and processing capabilities beyond a computer’s standard ports. Thin Mac® and Windows®(1) computers with Thunderbolt™ 3 ports still offer tremendous processing power, but for many, such as pros in the creative fields, onboard processing power alone is not enough. Fortunately, you don’t have to limit your choices to desktop workstations—think external. Sonnet’s Echo™ Express SEL (Thunderbolt 3 Edition) enables you to connect a single low-profile PCIe card outside of the computer. Through its x8 PCIe 3.0 slot, this little expansion system supports many Thunderbolt-compatible 16Gb and 8Gb Fibre Channel, 40Gb and 10 Gigabit Ethernet, video capture and processing, SAS and SATA host bus adapters, and RAID controller cards.

The Echo Express SEL (Thunderbolt 3 Edition) features 40Gbps Thunderbolt 3, which offers double the speed and connectivity of Thunderbolt 2, and yields up to 2750 MB/s of PCIe 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 the most 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) peripheral devices, Thunderbolt 3 is a leap forward in every way.

Key Features

• Connects a PCIe Expansion Card to Computers Without Slots—Use high-performance PCIe cards with any Mac or Windows PC with a Thunderbolt 3 port
• One PCIe 3.0 x8 Slot—Supports low-profile card
• 40Gbps Thunderbolt 3 Interface—Offers 2750 MB/s of PCIe bandwidth, doubling the performance of Thunderbolt 2
• Small Package, Full Performance—Smallest Thunderbolt 3-to-PCIe card expansion system available, supports the most popular low-profile, Thunderbolt-compatible PCIe cards at full performance
• Two Thunderbolt 3 Ports—One port reserved for connection to the computer; second port supports daisy-chaining of up to five additional Thunderbolt(5) devices to your computer, attaching a single USB(6) peripheral device, or connecting up to two 4K displays or one 5K display(4)
• Remarkably Quiet—Temperature-controlled, variable-speed fan automatically and quietly cools the card  
• Energy Saver Mode—Powers on/off automatically with the computer
• Rugged Aluminum Housing—Provides robust and secure protection
• Power for Peripherals—Provides up to 15W of power to connected peripheral or host
• Thunderbolt 3 Cable & ThunderLok 3 Included—Includes 0.5-meter Thunderbolt 3 (40Gbps) cable and ThunderLok 3 Thunderbolt connector retainer clip to secure cable from accidental disconnections

Small Package, Full Performance

Measuring just 4 inches wide by 8.4 inches long by 2.8 inches tall, the Echo Express SEL is ideal for use in circumstances where connecting a single low-profile PCIe card is required. Many of the most popular Thunderbolt-compatible high-speed networking and storage controller cards are a perfect fit, and even the BlueFish 444 Epoch 4K Neutron video card can be accommodated.

Thunderbolt 3 - The USB C That Does It All

The Echo Express SEL (Thunderbolt 3 Edition) includes two Thunderbolt 3 ports; the first connects it to your computer, while the second supports daisy chaining of up to five additional Thunderbolt peripheral devices to a single port on your computer. The SEL 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 SEL also provides full support for connecting two 4K displays @ 60Hz or one 5K display @ 60Hz(4). For connected peripherals requiring extra power, 15 watts is provided to connected bus-powered devices.

Connect computer to one port on the Echo Express SEL (Thunderbolt 3 Edition) and daisy chain up to 5 additional Thunderbolt devices (plus two 4K monitors, one 5K display, or one USB 3.0 device)

Smart Design, Inside and Out

Constructed of rugged and lightweight aluminum, the outer shell of the Echo Express SEL securely protects the installed PCIe card. The card is protected inside, too—the Echo SEL employs a variable-speed, temperature-controlled fan to ensure the card and chassis’ components remain reliably cool. The fan automatically speeds up as necessary to cool the installed card when it’s hot, and slows down when it’s cool. Since Echo Express 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.

Quiet, Please

The Echo Express SEL is designed to be ultra-quiet so that it can be comfortably used in noise-sensitive environments. The airflow path within the chassis has been specially designed to enable the fan to quietly and efficiently cool the installed card at all times, even during peak operation.

Designed for Low-Profile PCIe Cards

The Echo Express SEL supports one half-length (up to 6.6 inches long), low-profile, single-width PCIe card; PCIe 1.1, PCIe 2.0 and PCIe 3.0 cards are supported.
