Designed to boost system performance whether you are building a gaming system or looking to streamline content creation, the B660M-A gives you ample power to complete important tasks efficiently. Laying the foundation of this motherboard is the Intel B660 chipset, giving you access to an LGA 1700 socket.

This motherboard features four DDR4 RAM slots, four SATA III slots, and two M.2 storage interfaces. Equip your system with an array of graphics and utility cards using the onboard PCIe 4.0 x16, PCIe 3.0 x4, and PCIe 3.0 x1 slots. USB 2.0 ports allow you to connect a wide range of peripherals including keyboards, mice, and headsets, while the USB 3.2 Gen 1 ports give you enhanced connectivity speeds suitable for resource-demanding devices such as external storage drives. Connect wireless peripherals such as headphones thanks to supporting for Bluetooth 5.2. If you are relying on integrated graphics from the processor with this motherboard, you can connect displays to the HDMI or DisplayPort outputs. Wi-Fi 6 (802.11ax) capabilities allow you to easily connect to your home or business' wireless network while an RJ45 2.5 Gigabit Ethernet port offers a wired connection that is suitable for competitive online gaming or uploading content online. This motherboard is compatible with Windows 11 and Windows 10 (64-Bit) operating systems.

User-Friendly Design

EZ Debug LED

Onboard LEDs for key components will indicate the source of any problems so you know exactly where to look to get your system up and running again.

XL Clip

The enlarged PCIe clip assists you in swapping or removing devices easier from the PCIe slot while reducing the chance of damaging the PCIe clip during installation.

Keep Out Zone

MSI motherboard circuitry ensures the case standoff keep out zones are pure and clean, preventing any component compact or damage to the motherboard. Additionally, protective paint is printed around each screw hole to prevent parts from being scratched during installation.

PCIe 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.

Double ESD Protection

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

Cooling Features

Keep your components operating at ideal temperatures thanks to this motherboard's enhanced cooling features. Featuring an extended heatsink design, M.2 Shield Frozr, Fully Fan control, Frozr AI Cooling, and System Cooling all work together to ensure your components remain cool even under high loads while gaming or creating content.

Fully Fan Control & FROZR AI Cooling

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 CPU and motherboard, which will adjust the fan speeds automatically. FROZR AI Cooling allows the MSI AI Engine to detect CPU and GPU temperatures and automatically adjust fan settings of systems fans to three different values: performance mode, silent mode, and a custom manual mode.

Connectivity Features

Gen 4 PCIe and M.2

Gen 4 PCIe has a data transfer solution with 64 Gb/s of transfer bandwidth, double that of the previous PCIe generation. PCIe 4.0 also maintains both backward and forward compatibility with older and newer PCIe specifications.

Intel Optane Memory

Enjoy the performance of an SSD on your HDD by coupling it with an Intel Optane Memory device. Intel Optane technology provides an unparalleled combination of high throughput, low latency, high quality of service, and high endurance.

USB Front Type-C

A USB Front Type-C header allows users to connect the latest USB devices to the front of their USB Type-C compatible case.


Connect to your network wirelessly with Wi-Fi 6 (802.11ax) technology, giving you boosted wireless speeds and efficiency, suitable for uploading content and downloading large files. Additionally, this motherboard features a 2.5 Gigabit Ethernet port for wired networking.
