Know before you buy
The chassis supports one half-length, full-height, single-width PCIe 3.0 x8 card. It is designed for professional-grade cards such as high-speed networking, storage controllers, or audio interface cards.
The unit includes an internal power supply and a 6-pin PCIe power connector to support cards that require extra power. Please verify that your specific card's power requirements do not exceed the chassis's internal power delivery capabilities.
Yes, the Echo Express SE1 is compatible with both macOS and Windows 10 systems equipped with a Thunderbolt 3 port. Ensure your computer's drivers are up to date to ensure seamless integration.
The chassis features two Thunderbolt 3 ports, allowing you to connect your computer to the first port and daisy-chain up to five additional Thunderbolt devices to the second port. This helps keep your workspace organized by reducing the number of cables connected directly to your computer.
The SE1 uses an active cooling fan to maintain optimal temperatures for your PCIe card. While it is designed for professional environments, the fan will produce a low-level hum during operation, which is standard for active cooling systems in compact enclosures.
While the chassis uses Thunderbolt 3, it is generally not compatible with older Thunderbolt standards without specific adapters. For the best performance and stability, it is recommended to use this with Thunderbolt 3 or Thunderbolt 4 host ports.
