SKU CH-RQTF-QTRGC MPN ECHO-EX-SE3E-T3

Connects three full-height PCIe cards via Thunderbolt 3 at 40Gbps bandwidth

  • Connect three full-height PCIe cards via Thunderbolt 3
  • 40 Gbps bandwidth for high-speed data transfer
  • Three PCIe 3.0 slots: one x4 and two x8 electrical
  • Supports one double-width or three single-width cards
  • macOS 10.12.6+, Windows 10 1809+, Linux Kernel 5.0+

Three-slot Thunderbolt 3 expansion

The Sonnet Echo Express SE IIIe connects three full-height PCIe cards to any computer with Thunderbolt 3 ports. It provides three PCIe 3.0 slots: one x8 mechanical running at x4 electrical and two x8 mechanical at x8 electrical. A 6-pin Mini-Fit Jr connector supplies supplemental power for cards that require it. The desktop chassis accepts cards up to 7.75 inches long.

Suits creative pros needing capture or RAID cards

Professionals who rely on video capture, audio DSP or RAID controllers gain the bandwidth of a 40Gbps Thunderbolt 3 link. Mac users need macOS 10.12.6 or later; Windows users need Windows 10 64-bit version 1809 or newer; Linux users require kernel 5.0 or higher. Buyers without a Thunderbolt 3 port on their host computer cannot use this enclosure.

Adds three slots over a single cable

One Thunderbolt 3 cable carries data for all three cards while the included 12V power adapter feeds the chassis and the internal 6-pin connector. The compact desktop form factor sits beside a workstation without occupying internal drive bays or motherboard slots. It frees the host system from adding a second PCIe riser or a larger chassis.

商品問答

What Thunderbolt 3 host do I need to connect this expansion system?

You need a Mac running macOS 10.12.6 or later, a Windows 10 64-bit PC on version 1809 or newer, or a Linux machine with kernel 5.0+. All hosts must provide a Thunderbolt 3 port.

Can I keep my older Thunderbolt 2 Mac and use this enclosure?

Yes, with an Apple Thunderbolt 3 to Thunderbolt 2 adapter and a Thunderbolt 2 cable, both sold separately, a Mac with Thunderbolt 2 ports can connect to the unit.

How do I verify the enclosure is delivering 40Gbps bandwidth after setup?

Check the system report on macOS or Device Manager on Windows to confirm the link shows Thunderbolt 3 at 40Gbps and that each installed PCIe 3.0 card appears at its expected x8 or x4 electrical width.
