Connect PCIe Cards

Use multiple high-performance PCIe cards with any computer with a Thunderbolt 3 port.

40Gbps Thunderbolt 3 Interface

Offers 2750 MB/s of PCIe bandwidth, doubling the performance capabilities of Thunderbolt 2.

Pro Performance. Compact Design.

Takes up little space on the desktop, but large enough to support nearly every Thunderbolt-compatible non-GPU PCIe card at full performance.

Two Thunderbolt 3 Ports

One port connects to computer; second port supports daisy-chaining of up to five additional Thunderbolt peripheral devices.

Remarkably Quiet

Temperature-controlled,variable-speed fan automatically and quietly cools the cards.

Energy Saver Mode

Powers on/off automatically with the computer.

Rugged Aluminum Housing

Provides robust and secure protection.

Pro Power

NEW - Auxiliary PCIe power connector for a power-hungry card; daisy chain port provides up to 15W of power to connected peripherals.

Nearly Every Thunderbolt-Compatible, Non-GPU PCIe Card Supported

Smaller than the 3-slot Echo Express III-D (Thunderbolt 3 Edition), the Echo Express SE IIIe is still large enough to support nearly every Thunderbolt 3 compatible card available. With its three x8 slots, the SE IIIe supports PCIe 3.0, PCIe 2.0, and PCIe 1.1 cards up to 7.75 inches long. Do you have a card in mind but aren’t sure it’s compatible? We’ve put together a list in our supporting PCIe Card Thunderbolt Compatibility Chart (PDF). There you’ll find cards identified as conforming to Thunderbolt technology requirements, and organized by fit and power compatibility with specific expansion system.

Three PCIe 3.0 Slots for Demanding Professional Needs

‍Echo Express SE IIIe’s PCIe 3.0 x8 slots support three half-length+, full-height, single-width PCIe cards, or one single-width card plus one double-width card.

Double-width?

‍Some specialty cards, such as RME’s HDSPe MADI FX, Blackmagic Design’s DeckLink 4K Extreme, and the Lynx AES16e 50, include a daughter card that mates with and provides additional external connections to the main card.

Power to Spare

‍Echo Express SE IIIe includes an auxiliary PCIe power connector, enabling you to install a card requiring extra power, such as the AJA® Kona® 5 or Blackmagic DeckLink 4K Extreme 12G, and Bluefish444’s Epoch and KRONOS SDI cards.
