PCIe Card Compatibility
For a list of compatible PCIe cards, view the PDF of Sonnet's PCIe Card Thunderbolt Compatibility Chart
- Two Thunderbolt 3 ports
- 12V power port
- 6-pin Mini-Fit Jr (same type as on legacy Mac Pro motherboard; provides power for PCIe card that requires supplemental power)
- One x8 mechanical (x4 electrical) PCIe 3.0
- Two x8 mechanical (x8 electrical) PCIe 3.0
PCIe Cards Supported
- One half-length+ (up to 7.75 inches long), double-width, full-height x8 PCIe card, plus one single-width card or
- Three half-length+, single-width, full-height x8 PCIe cards
- Universal 120W, 100-240V, 50-60 Hz
- NRTL Certified
- 0ºC to 35ºC (32ºF to 95ºF)
- 6.5 x 11 x 4.6 in. (16.5 x 27.9 x 11.7 cm)
- Echo Express SE IIIe
- Universal power adapter
- Power cord
- 0.7-meter Thunderbolt 3 (40Gbps) cable
- ThunderLok 3 Thunderbolt Connector Retainer Clip(1)
- ThunderLok 3 compatible specifically with Sonnet 0.5- and 0.7 meter Thunderbolt 3 cables; Sonnet 1- and 2-meter Thunderbolt 3 cables require ThunderLok 3L.
- While the Echo Express SE IIIe features a 40 Gbps Thunderbolt 3 interface, some computers equipped with Thunderbolt 3 use an implementation of Thunderbolt 3 technology that limits PCIe performance to 20 Gbps. 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.
- Full performance requires the use of the included Thunderbolt 3 (40Gbps) cable, or comparable Thunderbolt 3 (40Gbps) cables; look for the Thunderbolt icon AND the number 3 on the connector housings to identify these cables.
- Assuming that a 40Gbps Thunderbolt 3 connection is established, all Thunderbolt 3 computers support one 4K monitor directly attached to the pass-through Thunderbolt 3 port, without affecting PCIe bandwidth to the device. Using two 4K monitors or a single 5K monitor attached to the pass-through Thunderbolt 3 port reduces available PCIe bandwidth to the device. Two 4K monitors requires either: 1) for Thunderbolt 3 Macs or for Windows Thunderbolt 3 PCs that support two monitors—a Thunderbolt 3 to Dual DisplayPort adapter; or 2) for Windows Thunderbolt 3 PCs that support two monitors—a 4K monitor with multi-stream transport support (DP out).
- 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).
- 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).
