The Echo Express SE I Desktop Thunderbolt 2 to PCIe Card Expansion System from Sonnet supports most Thunderbolt-compatible cards, including PCIe 1.1, PCIe 2.0, and PCIe 3.0 cards up to 7.75" long. It is suitable for connecting one professional video capture, audio interface, SAS or SATA HBA, 16Gb or 8Gb Fibre Channel, 10Gb Ethernet, or RAID controller PCIe card to any Mac or Windows PC with a Thunderbolt port. The PCIe expansion slot is necessary to install specialty audio, video, networking, and storage controller interface cards. The SE I features Thunderbolt 2 technology, which provides ample bandwidth for many of the demanding, high performance PCIe cards, and incorporates support for the DisplayPort 1.2 protocol, which enables video streaming to a 4K video monitor.

Note: PCIe cards sold separately

Form Factor 
The Echo Express SE I is small and light for use in situations where connecting only a single PCIe card is required. The SE I is designed to have a small footprint, yet it's large enough to support the vast majority of Thunderbolt-compatible PCIe cards. The SE I's small size doesn't limit its performance. When installed in this system, a card will perform the same as when installed in an Echo Express SE II, Echo Express III-D, or Echo Express III-R.
Thunderbolt 2 Technology 
The SE I features Thunderbolt 2 technology, which provides ample bandwidth for many of the demanding, high performance PCIe cards and incorporates support for the DisplayPort 1.2 protocol, which enables video streaming to a 4K video monitor. While delivering maximum performance when connected to a computer with Thunderbolt 2 ports, the SE I is also fully compatible with computers with 10 Gb/s Thunderbolt technology, supporting cards at full-performance. And like the other Echo Express models, the SE I includes two Thunderbolt ports to support daisy chaining of up to six devices from a single port on your computer.
Supports Thunderbolt-Compatible PCIe Cards 
Able to accommodate cards up to 7.75" long, Sonnet's Echo Express SE I supports Thunderbolt-compatible cards. PCIe 1.1, PCIe 2.0, and PCIe 3.0 cards are also supported.
Smart Design Inside and Out 
Constructed of rugged and lightweight aluminum, the outer shell of the Echo Express SE I securely holds the installed PCIe card. The card is protected inside, too. Instead of using a fixed speed fan that may not reliably cool a hot-running card or a fan with a user-controlled switch, the SE I employs a variable-speed, temperature-controlled fan to ensure that the card and chassis' components remain reliably cool. The expansion chassis' 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.
PCIe 2.0 Slot and Space for a Daughter Card 
The Echo Express SE I's PCIe 2.0 slot supports one half-length+ (up to 7.75" long), full-height, single or double-width PCIe card. Some specialty cards, such as RME's HDSPe MADI FX card, 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. The daughter card occupies the adjacent space without filling a PCIe slot.
The Echo Express SE I 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 temperature-controlled, variable speed fan to quietly and efficiently cool the installed card at all times.
Strong Link in the Chain 
This Sonnet solution supports daisy chaining of additional Thunderbolt technology-enabled peripherals such as an additional Echo Express, the Apple Thunderbolt display, video capture devices, and data storage devices. For connected devices requiring extra power, 10W is provided through the daisy chain port to peripherals.
Thunderbolt Cable and ThunderLok Included 
Sonnet includes a Thunderbolt cable to connect the Echo Express SE I to your computer and a ThunderLok Thunderbolt connector retainer clip to secure the cable to the Echo chassis. Thunderbolt connectors are held in place by friction, which works well in situations where equipment remains undisturbed while operating. Sonnet's ThunderLok prevents accidental cable disconnections from the Echo chassis and is easy to install and use: 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, ThunderLok does not attach to the connector, but remains on the cable so it won't get lost when not in use.


Form Factor Desktop Thunderbolt 2-to-PCIe card expansion system

PC with a Thunderbolt or Thunderbolt 2 port *
Windows 8 and 7 

Important Note: *Windows requires a Thunderbolt 2 interface in the computer and in the expansion chassis to support more than two PCIe controllers. Note that some PCIe cards have a bridge to multiple controllers, so it is possible for a single dual-controller PCIe card to reach the limit if not connected via Thunderbolt 2. Not all Mac-compatible PCIe cards are also compatible with Windows.
