Welcome to Magma, a brand of One Stop Systems.
Our Magma products haven’t changed so customers can still expect the same level of performance and quality!


The Magma Thunderbolt products provide an “outside-the-box” solution for using PCIe cards with Thunderbolt equipped computers. Many companies have a significant investment in PCIe cards but as the size of computers gets smaller, available expansion slots have been reduced or completely eliminated. Our Magma Thunderbolt products provide a “migration path” to Thunderbolt enabled computers while protecting your investment in PCIe hardware.

Magma and One Stop Systems’ expertise in developing products that extend PCIe signals over a cable and outside of the computer provides a reliable foundation for producing rock solid products that perform as expected even in the most demanding configurations.
