Build your next system around a 12th generation Intel processor with the MAG B660 TOMAHAWK WIFI LGA 1700 ATX Motherboard from MSI. Designed to provide power and take advantage of resource-demanding components, this motherboard balances performance with style suitable for computer enthusiasts and gamers.

Designed with the B660 chipset, this motherboard features the LGA 1700 socket, four dual-channel RAM slots, and three M.2 slots allowing you to take advantage of the full power of 12th generation Intel processors. The Six SATA III ports allow users to create large storage drive arrays for large file libraries. Two PCIe x16 and one PCIe x1 slot allow you to install high-end graphics cards and other expansion cards. Connect to a wireless network with Wi-Fi 6 (802.11ax) technology, or make a wired connection with the integrated 2.5 Gigabit Ethernet port. Resource-demanding peripherals such as storage drives can be connected to the USB 3.2 Gen 2 and Gen 2x2 ports to quickly transfer data with enhanced speeds. USB 2.0 ports are also available for lower-powered devices such as mice and keyboards. Wireless peripherals such as headphones and controllers can be connected thanks to integrated Bluetooth 5.2 technology. This motherboard is compatible with both Windows 10 and Windows 11 (64-Bit).

Premium Hardware Design
Designed for gamers and enthusiasts, this motherboard features a 12+1+1 duet rail power system and 8+8 pin power connectors to power the Core Boost technology which enhances the performance of your multi-core Intel processor. Easily overclock your CPU thanks to the MSI Game Boost technology which allows you to perform 1-second immediate overclocking. The motherboard's Digital Power Design, Overvoltage Protection, Load-Line Calibration, Double Power Connectors, and Supplemental PCIe Power Connector, all work together to ensure proper electrical management through your system to stabilize your system, especially under high loads.
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.
DIY Friendly
Whether this is your first time building a custom computer or you are an experienced enthusiast, MSI provides several features to make the process easier. The pre-installed I/O shield simplifies installation and protects your I/O ports while also preventing electrostatic discharge damage, while the EZ M.2 Clip allows you to install M.2 SSDs effortlessly. The standoffs are marked and painted on the motherboard, ensuring you avoid dangerous collisions while installing your components, and MSI's atypical PCB design makes cable routing more accessible.
Enhanced Protection
This motherboard is designed with a PCB that has been optimized for higher bandwidth and faster transfer speeds, which also benefits reliable circuit transmission with 2oz thickened copper that allows the motherboard to easily withstand overclocking while improving heat dissipation and system reliability. The MSI PCI Express Steel Armor slot is secured to the motherboard with extra solder points to support the weight of heavy graphics cards and prevent GPU sag which can damage the PCIe slots. Double ESD protection doubles up the grounding layer around the mounting holes, preventing static discharge surges from damaging the motherboard.
Gen 4 M.2
Utilizing the 12th generation Intel processors, MSI B660 motherboards feature the Gen 4 M.2 which provides transfer speeds up to 64 Gb/s.
Memory Boost
MSI has tested this motherboard with various memory brands to ensure your system is stable as you create or game. Dual-channel DDR4 RAM slots with XMP support can run overclocked memory with speeds up to 4800 MHz.
Networking
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. MSI's LAN Manager software prioritizes your connection, reducing lag, and keeping your online experience smooth.
Audio Features
Immerse yourself in your favorite media with Audio Boost technology, consisting of high-quality audio capacitors, 3.5mm audio jacks with an S/SPDIF, and a dedicated high-definition audio processor delivers clean and refined audio. The printed circuit board separates audio layers for clean left and right channels, while also isolating audio circuits, reducing crossover talk, and electrical interference. De-pop protection removes the popping sound from plugging or unplugging audio devices to protect your ears.
USB Type-C Connections
The USB Front Type-C header allows you to connect the latest USB devices, while the rear USB Type-C port features the USB 3.2 Gen 2x2 interface which offers data transfer speeds up to 20 Gb/s.
Customization
The Mystic Light Extension pin header provides users an intuitive way to control additional RGB strips and other RGB peripherals added to a system, without needing to buy a separate RGB controller. Additionally, wireless devices can also be controlled by the MSI Center. Ambient Link synchronizes MSI Mystic Light products with on-screen gaming and scenarios, as well as compatible lighting accessories.
BIOS & Included Software Features
The MAG B660 TOMAHAWK WIFI provides you with a suite of programs that allow you to easily manage your hardware and overclock your system with ease. Click BIOS 5 allows you to fine-tune your motherboards performance with XMP profiles, VMD (Volume Management Device) enabling direct control of NVMe SSDs, M-Flash BIOS flashing, and a Hardware Monitor. MSI Center unifies the suite of MSI software utilities into a single centralized application, giving you control over RGB settings, fan settings, the LAN manager and hardware, and system monitors. The Resizable BAR is advanced PCIe feature within the BIOS that enables the CPU to access the entire GPU frame buffer at once and improve performance.
Windows 11 Certified
Featuring an integrated TPM 2.0 header, the MAG B660 TOMAHAWK WIFI has been tested by the MSI R&D team to be fully compatible with Windows 11.
