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.

M.2 SHIELD FROZR

World’s fastest SSDs can start to lower performance when getting hot. Part of the motherboards heatsink design, M.2 SHIELD FROZR is the next generation M.2 thermal solution to avoid this by offering the best thermal protection to make sure that SSD maintains maximum performance.

FULLY CONTROLLABLE IN BIOS AND SOFTWARE

MSI motherboards let you manage speeds and temperatures for all your system and CPU fans. Total Fan Control allows you check your primary system characteristics in a simplified graphical interface. You can also set up to 4 temperature targets for CPU and motherboard, which will adjust the fan speeds automatically.

10 + 2 + 1 DIGITAL POWER WITH DOUBLER DESIGN

Unleash and sustain maximum performance with an aggressive VRM design built with a total of 10 phases Digital Power with Doubler Design. Combining exclusive Core Boost technology, PRO series motherboard is ready to sustain heavy daily work.

POWER DESIGN

LIGHTNING GEN 4 PCI-E

MSI lightning Gen 4 PCI-E is the latest and the fastest PCI-E data transfer solution with 64GB/s of transfer bandwidth that has doubled compared to its previous generation.
