PRO series helps users work smarter by delivering an efficient and productive experience. Featuring stable functionality and high-quality assembly, PRO series motherboards provide not only optimized professional workflows but also less troubleshooting and longevity.

THERMAL SOLUTION FOR MORE CORES AND HIGHER PERFORMANCE

With more cores’ processors, thermal and power design is more important to make sure the temperature keeps lower. MSI extended PWM heatsink with 7W/mK thermal pad ensures even high-end processors to run in full speed with MSI motherboards.

FAST AND FUTURE-READY STORAGE

MSI PRO series motherboards support all the latest storage standards, which allows users to connect any ultra-fast storage device. Higher efficiency makes your work easier.

PCB WITH 2OZ THICKENED COPPER

An enhanced PCB design with 2oz thickened copper increases conductivity, improving heat dissipation and performance reliability especially during overclocking.
