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.
Detecting CPU & GPU temperatures and automatically adjusting fan duty of system fans to a proper value by adopting MSI AI ENGINE.
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.
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.
Ran into trouble? Onboard LEDs for key components will indicate the source of the problem so you know exactly where to look to get it up and running again.
The enlarged PCI-E clip helps you swap or remove your devices easier. Keep the PCI-E slot stronger and safer.
MSI motherboards circuitry ensure the case standoff keep out zones are pure and clean, preventing any component contact or damage to the motherboard.
Protective paint is printed around each screw hole to prevent parts from being scratched.
MSI PCI Express Steel Armor slots are secured to the motherboard with extra solder points and support the weight of heavy graphics cards. When every advantage in games counts, Steel Armor shields the point of contact from electromagnetic interference.
Double ESD protection doubles up the grounding layer around the mounting holes, preventing static discharge surges from damaging the motherboard.
The most important thing of DIY is expandability. MSI PRO series motherboards feature plenty possibility for prosumers’ need. Stable LAN, faster storage and USB transfer speed and other expandable connectors are ready to enlarge your flexibility.
2.5Gbps LAN provides incredible data transfer speed faster than general Gigabit LAN. This is a premium solution for demanding users.
The WIFI 6 adopts the latest OFDMA and two-way MU-MIMO technologies and could provide up to 4X network capacity and efficiency in the high signal density environment. Comparing to the WIFI 5, which can only send the data packet to one device at a time on each channel, the WIFI 6 could combine the packet, separate to several devices and allow signals from the different devices bundled together. This new technology provides all the devices in the same network environment with same and harmonious traffic bandwidth in an efficient way.
MSI LAN Manager automatically classifies and prioritizes the latency-sensitive applications, giving you the best online experience with low latency.
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.
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.
Utilizing 12th Gen Intel Core processors, MSI B660 PRO 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.
PC Enthusiasts can now enjoy the performance of an SSD on their HDD by coupling it with the new Intel® Optane™ Memory device. Intel® Optane™ technology provides an unparalleled combination of high throughput, low latency, high quality of service, and high endurance.
MSI motherboards support USB Front Type-C that allows gamers to connect with the latest USB devices. Built up a system with MSI PC case to have the most convenient experience.
Add more 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.

Moreover, with years of experience in creating performance enhancing tools that are easy to use, only the highest quality applications are at your disposal. The extensive features let you fine-tune your system to deliver reliable maximum performance.
MSI OC LAB does not merely work hard on extreme overclocking. The XMP memory profile has great improvement on performance and efficiency for B660 . Easy to enable XMP profile with auto power settings to get the best memory speed and stability.
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.
Make sure you enjoy the purest sound quality in both stereo and surround sound.
A high fidelity sound experience with exceptional acoustics and realism for studio level headphones is ensured.
Keep you sound perfect by transmit your aduio with pure digital signal.
Like a dedicated sound card, audio components and circuits have been laid on a reserved motherboard section and electrically isolated.
Using separated layers in the PCB ensures equally pristine sound quality for both left and right audio channels.
MSI brand new MSI Center unifies a suite of MSI software utilities into a single centralized application. Take control of advanced motherboards features and unleash endless possibilities.
Get more from a loaded BIOS designed for ease of use. Fine-tune the motherboard for gaming performance, efficiency, or overclocking world records!
Resizable BAR (Re-Size BAR) is an advanced PCI Express feature that enables the CPU to access the entire GPU frame buffer at once and improve performance.
All MSI PRO series motherboards have SECURITY function in BIOS to protect every private files for no matter business or daily use.
Secure boot is a security standard to make sure that a device boots using only software that is trusted. When the PC starts, the firmware checks the signature of each piece of boot software, including UEFI firmware drivers, EFI applications, and the operating system. The PC boots while the signatures are valid.
