High-Performance 
& Robust Capacity, 
Featuring Two 5.25-inch Bays
Engineered to Magma’s ‘mission critical’ standards for 
performance and reliability, ROBEN-3TX features three (3) 
full-length, full-height PCIe slots with a robust, high speed 
backplane. The rack-mountable aluminum chassis was 
designed for integrated removable storage expansion, 
providing flexibility with two customer configurable 5.25” 
expansion bays, a 520-watt fanless power supply, 
auxiliary power, and features Magma’s exclusive quiet 
cooling technology. From initial concept, the ROBEN-
3TX Thunderbolt configuration has been precision 
engineered to be the “perfect sidekick” for the new 
Apple Mac Pro and other Apple and PC devices.
Fuel your creative genius by adding a host of specialty PCIe 
cards to any Thunderbolt-equipped computer to achieve 
expanded performance in every working environment. 
ROBEN-3TX’s patented performance optimizing backplane 
seamlessly integrates PCIe expansion, storage, and 
Thunderbolt connectivity and ensures that all devices 
installed in the system operate with the maximum 
possible speed. This design gives audio engineers, video 
producers, game developers, and graphic designers 
the same level of data fidelity that had previously been 
reserved for defense and aerospace industry projects.
With the fastest card-to-card communication, integrated 
high capacity storage, and the largest expansion 
capacity on the market, ROBEN-3TX sets the bar 
for high-end Thunderbolt-based computing.
Provides expansion for up to three 
PCIe-based, full length cards
