    Product Overview



    The PRO Series motherboards fit in any PC. Quality you can trust with top performance and clever business solutions are key aspects of these motherboards. Make your life easier and boost your business with the super stable, reliable and long-lasting PRO Series motherboards.
    With traditional memory design the memory signals are often distorted by electromagnetic signals from other components, making the system perform slower or become unstable. MSI introduces DDR4 Boost technology with optimized traces and fully isolated memory circuitry. This design ensures the memory signals stay pure for optimal performance and stability.
    MSI USB 3.1 GEN2
    Transferring your favorite games, music and movies over USB has never been faster. USB 3.1 Gen2 enables lightning fast transfer speeds up to 10Gb/s!
    2X faster than USB 3.1 Gen1
    20X faster than USB 2.0
    Up to 10Gbps data transfer bandwidth
    Boost transfer rate for your PC and peripherals
