Power Design

12 + 1 + 1 Duet Rail Power System

Unleash and sustain maximum performance with a VRM design built with a digital CPU power system. Combining 8 + 8-pin power connectors and exclusive Core Boost technology, this motherboard is prepared to sustain heavy gaming loads. Additionally, load line calibration makes sure your CPU voltage remains stable under any load.

Core Boost & Game Boost

Core Boost technology combines MSI`s premium layout and digital power design, which allows for faster and undistorted current delivery to the CPU at pin-point precision. This creates the perfect conditions for multi-core CPU performance under high loads. Overvoltage protection prevents potential short-circuit damage to the CPU and other critical components. Additionally, there are two 8-pin connectors that deliver adequate power, even to an overclocked multi-core CPU. Quickly overclock your CPU with MSI Game boost, enabling one-second overclocking and giving you the performance boost you need to get extra FPS.

Cooling Features

Extended Heatsink Design

With multi-core processors, thermal and power design are more important to make sure the temperature remains low. MSI`s extended PWM heat sink and enhanced circuit design ensures even high-end Intel CPUs run at full speed.

Total Fan Control

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

M.2 Shield Frozr

The fastest SSDs can start to slow down when getting too hot. Part of this motherboard`s heat sink design, M.2 SHIELD FROZR is an M.2 thermal heat sink designed to make sure that M.2 SSDs maintain maximum performance, even under heavy loads.

Frozr AI Cooling

Frozr AI Cooling detects CPU & GPU temperatures and automatically adjusts fan settings to either performance mode, silent mode, or manual mode, thanks to the MSI AI Engine. Use the MSI AI Engine to control and create your own fan profiles

Optimized for Water Cooling

A dedicated water pump header supports up to 3 amps, giving you full control of the water pump speed. A clearly marked `keep-out-zone` allows for easy and safe installation of any liquid cooling setup.

Protective Features

PCB Design

The PCB design has been optimized for higher bandwidth and faster transfer speeds, which is also beneficial for reliable circuit transmission.

Steel Armor

MSI PCI Express Steel Armor slots are secured to the motherboard with extra solder points to support the weight of heavy graphics cards. When every advantage in gaming counts, Steel Armor shields the point of contact from electromagnetic interference, protecting your components.

Double ESD Protection

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

DIY Friendly Features

Pre-Installed I/O Shield

The pre-installed I/O shielding helps make your installation process safer and easier. The patent-pending design from MSI protects your I/O ports and also prevents electrostatic discharge damage, making your motherboard a strong foundation for competitive gaming.

Keep-Out Zone and Avoid Collision Paint

MSI motherboards ensure the case-standoff keep-out zones are clean and visible, preventing any component contact or damage to the motherboard. Protective paint is printed around each screw hole to prevent parts from being scratched when installed onto the motherboard.

EZ M.2 Clip

The EZ M.2 clip assists you in installing an M.2 SSD quickly without having to turn any screws.

Performance Features

Gen 4 M.2

Supporting 12th and 13th Gen Intel processors, MSI B660 motherboards feature Gen 4 M.2 with a transfer speed up to 64 Gb/s.

Gen 4 PCI-E

Gen 4 PCI-E provides 64 Gb/s of transfer bandwidth and maintains backward and forward compatibility with older and newer specifications. Optimized by a steel armor design and server grade PCB, users can enjoy next-gen devices without any compromise.

Memory Boost

MSI conducts thorough memory testing with the most popular memory brands under extreme conditions to ensure your system runs stable no matter what. MSI`s memory partners include brands like Corsair, Crucial, Kingston, G.Skill, and many more to optimize memory modules, configurations, and even improve overclocking.

BIOS & Software Features
