Sonnet Echo Express SE1 Thunderbolt 3 to Single Slot PCIE Expansion Chassis

Description

Lightly used Echo Express SE I Thunderbolt 3. Purchased new from B&H, used it occasionally for testing of PCIe cards. Great condition. PSU is included.
Original box, manual, and Thunderbolt cable is NOT included.
I also feel it's important to let everyone know that I have been burned several times by scam artists here on eBay. Therefore, all serial numbers will be recorded prior to shipment and any claims that the units arrived damaged or in a non working condition will be contested. Last, but not least, I DO NOT ACCEPT RETURNS FOR ANY REASON. So, please ask any and all questions BEFORE bidding!
Also, if you are inexperienced with this type of device, or simply don't know WTF you are doing, please don't buy from me. I am beyond burnt out dealing with buyers who haven't got a clue as to what they are doing, then blame me when things don't go as expected. I am NOT a reseller, I am NOT able to provide you with technical support, and I am NOT going to tolerate buyers who wanna pull scams or try to lie and state that the item was defective just so they can facilitate a return. I am not Amazon, so you dont get to "buy it to try it". You wanna pull that BS, buy elsewhere.
The Echo Express SE I Thunderbolt 3 to PCIe Card Expansion System from Sonnet provides a PCIe 3.0 x8 slot for Thunderbolt 3-equipped notebooks, SFF desktop systems, and other computers without a PCIe slot. The Echo Express SE I supports full-height PCIe cards, featuring a length up to 7.75". For supporting a wide variety of PCI cards, it sports one expansion slot that can accommodate double-width PCI cards or single-width PCI cards coming with a daughter card. 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, which operates over the Thunderbolt connection. There's also an integrated variable-speed fan for cooling your PCI card and the SE I's internal components.
The Echo Express SE I Thunderbolt 3 to PCIe Card Expansion System comes with two Thunderbolt 3 ports, letting you daisy chain up to six Thunderbolt devices to your computer. Each of the two Thunderbolt 3 ports transmits data at a rate of up to 40 Gbps and offers a USB Type-C design, so you can connect the included 1.6' Thunderbolt 3 cable on the first try. Moreover, a ThunderLok 3 Thunderbolt connector retainer clip is supplied to help ensure the cable stays connected to the chassis.
Note: The Echo Express SE I is not compatible with the DeckLink 4K Extreme 12G card due to daughter card mounting requirements.
General Features
PCIe 3.0 Slot and Space for a Daughter Card
The Echo Express SE I's PCIe 3.0 slot supports a half-length (up to 7.75" long), full-height, single- or double-width PCIe card. Some specialty cards, such as Blackmagic Design's DeckLink 4K Extreme, and RME's HDSPe MADI FX card, include a daughter card that mates with and provides additional external connections to the main card. The daughter card occupies the adjacent expansion slot space without requiring a PCIe slot.
Thunderbolt 3 Technology
The Echo Express SE I - Thunderbolt 3 edition includes two Thunderbolt 3 (USB-C) 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 SE I comes with USB 3.1 (10 Gbps) support, meaning you can connect a USB device to the second port using a proper cable or adapter. The SE I also provides full support for connecting two 4K displays @ 60 Hz or one 5K display @ 60 Hz. For connected devices requiring extra power, 15 watts is provided to connected bus-powered devices.
Smart Design
The Echo Express SE I - Thunderbolt 3 Edition's lightweight, yet rugged aluminum outer shell securely protects the installed PCIe card. Inside, the card is protected with a variable-speed, temperature-controlled fan, which ensures that the card and SE I's internal components remain reliably cool. The fan automatically speeds up as necessary to cool the optional PCIe 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.
Compatibility
Designed to accommodate cards up to 7.75" long, the Echo Express SE I - Thunderbolt 3 Edition supports most PCIe 3.0, PCIe 2.0, and PCIe 1.1 cards, which are compatible over a Thunderbolt connection.
Quiet Cooling
The Echo Express SE I is designed to be 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 PCIe card at all times.
Thunderbolt Cable and ThunderLok Included
To connect the Echo Express SE I - Thunderbolt 3 Edition to your computer, Sonnet includes a 1.6' (0.5m) Thunderbolt 3 (40 Gbps) cable and a Sonnet ThunderLok 3 Thunderbolt connector retainer clip to secure the cable to the Echo chassis. Accidental cable disconnection can lead to data loss. Sonnet's ThunderLok 3 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.
