Overview

Highlights

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.

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.

OPTIMIZED FOR WATER COOLING
Designed to support the most popular All-In-One & customized water cooling solutions on the market. A dedicated water pump PIN header supports up to 3 amp, giving you full control of the water pump speed. A clearly marked ‘keep-out-zone’ allows for easy and safe installation and a perfect fit.

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.

LIGHTNING GEN 4 M.2
Utilizing 3rd Gen Ryzen processors, MSI B550 motherboards feature latest Lightning Gen 4 M.2 which is the fastest onboard storage solution on the market with up to 64 Gb/s transfer speed.

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

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.

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. PCIe 4.0 maintains both backward and forward compatibility with older and newer specifications. Optimized by steel armor design and server grade PCB, you can enjoy next-gen devices without any compromise.

A HUGE STEP OF DDR PERFORMANCE
MSI OC LAB does not merely work hard on extreme overclocking. Compared to B450 motherboard memory A-XMP profile, MSI does have great improvement on performance and efficiency for B550 motherboards. Easy to enable A-XMP profile with auto power settings to get the best memory speed and stability.

CORE BOOST
Core Boost technology combines MSI's premium layout and optimized power design which allows for faster and undistorted current delivery to the CPU at pin-point precision. Not only supporting multi-core CPU, also creating the perfect conditions for your CPU overclocking.
