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.

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.

EZ DEBUG LED
Run into trouble? Onboard LEDs for key components will indicate the source of the problem so you know exactly where to look to get up and running again.

ULTIMATE MOTHERBOARD PROTECTION
Double ESD protection doubles up the grounding layer around the mounting holes, preventing static discharge surges from damaging the motherboard.

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.

USB 3.2 GEN 1
Transfer lots of data, music and movies over USB easier. USB 3.2 ports are ready in both front and rear IO, provides wide variety of options to connect your USB 3.2 devices.

MYSTIC LIGHT SYNC
EXTEND YOUR RGB EXPERIENCE WITH EASE
Add your color if you want! Mystic Light Extension pin header provides an intuitive way to control additional RGB strips and other RGB peripherals added to a system, without needing a separate RGB controller.

JRAINBOW
Connects 3-pin 5V Addressable LED strip

JRGB
Connects 4-pin 12V RGB LED strip

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

A HUGE STEP OF DDR PERFORMANCE
MSI OC LAB does not merely work hard on extreme overclocking. Compared to A320 motherboard memory A-XMP profile, MSI does have great improvement on performance and efficiency for A520 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.
