Connect three half-length, full-height PCIe cards to systems with a Thunderbolt 3 port using the Echo Express SE IIIe Thunderbolt 3 Expansion Chassis from Sonnet. The Echo Express SE IIIe is useful for expanding the connectivity of systems like the MacBook Pro, which does not have the PCIe slots needed for pros working in creative fields. Instead, the Echo Express SE IIIe connects to Thunderbolt 3 hosts to leverage this connectivity via PCIe expansion slots that are outside of the computer.

This chassis has two PCIe 3.0 x8/x8 slots and one PCIe 3.0 x8/x4 slot. These three slots can support one half-length+ (up to 7.75" long), double-width, full-height PCIe x8 card, plus one single-width card, or three half-length+, full-height PCIe x8 cards for video capture, audio DSP, 6Gb or 12Gb SAS or SATA host bus adapters, 10Gb, 25Gb, or 40Gb Ethernet cards, RAID controllers, and more. The Echo Express SE IIIe features two 40 Gb/s Thunderbolt 3 ports, one of which is used to connect to your host Windows, Mac, or Linux system and provides up to 100W of power.
