    SKU: PE3R / PE3R-3.3

    Need to upgrade your server or desktop computer?  Don’t want to lose your investment in your specialized PCI cards that won’t fit in your new computer? You can install practically any PCI card into the Magma PCI Expansion System and connect it through a PCI Express slot on your computer.

    Prolong Your Investment

    Magma’s 3 Slot PCI Expansion System provides a simple, cost-effective solution for expanding the capability of practically any computer, especially as PCI Express becomes the industry standard, the number of available PCI slots has been reduced or completely eliminated. Many companies have invested a lot time, energy and money in solutions built around conventional PCI hardware. The Magma 3 Slot PCI Expansion System provides a safe "migration path" to PCI Express while protecting your investment in PCI cards.

    Save Time, Money and Trouble

    The expansion chassis consists of a host interface card, a cable and a chassis. The expansion chassis is automatically configured by the System BIOS making all of the slots appear transparent within the host computer.

    Cost-Effective Migration and Increased I/O Capacity

    Magma expansion solutions provide a cost-effective migration path to new computers while maintaining a consistent PCI configuration. In addition, Magma products significantly increase (I/O) capacity and scalability. Multiple expansion systems can be combined to provide an almost unlimited number of PCI slots* to a single computer. This type of scalability is especially useful in industries such as Telecom, Data Acquisition, Video Monitoring, Server Storage and Manufacturing Test Fixtures.
