Expand Your Creativity: Pro-Level Performance with Three PCIe Slots
Your modern Mac or Windows computer is a powerhouse, but its slim design comes at a cost: no slots for the specialized PCIe cards your professional workflow depends on. The Sonnet Echo Express SE-IIIe is the definitive solution—a compact and quiet Thunderbolt 3 to PCIe card expansion system engineered to bridge the gap between your computer's power and your professional demands.
Harness the full-throttle speed of a 40Gbps Thunderbolt 3 interface. The SE-IIIe delivers a staggering 2750 MB/s of PCIe bandwidth, ensuring your most demanding cards run at their absolute peak. Whether you're using high-frame-rate 4K video capture cards, audio DSPs, 16Gb Fibre Channel adapters, or high-speed Ethernet cards, you can finally work without performance bottlenecks. The SE-IIIe empowers your hardware to perform as intended.
Engineered for the creative workspace, the SE-IIIe features a rugged aluminum enclosure that's both durable and desktop-friendly. Its versatile interior accommodates three single-width, full-height cards or a combination of one double-width and one single-width card. For power-hungry hardware like the AJA KONA 5, a dedicated auxiliary power connector is built-in to provide stable power. A large, temperature-controlled Noctua fan cools your cards efficiently while remaining whisper-quiet, making it ideal for noise-sensitive studio environments.
Streamline your setup with dual Thunderbolt 3 ports, allowing you to connect to your computer and daisy-chain up to five additional Thunderbolt peripherals from a single port on your computer. The system arrives as a complete, secure package, including a 0.7m 40Gbps Thunderbolt 3 cable and a ThunderLok 3 retainer clip to prevent accidental disconnections and ensure your workflow remains uninterrupted.
