MAG B860 Tomahawk WiFi
MAG B860 Tomahawk WiFi Specifications Review
MAG B860 Tomahawk WiFi by MSI is a Standard-ATX form factor motherboard based on the mid-range B860 chipset and LGA 1851 socket, providing a balanced set of features and connectivity. It is designed to support DDR5 memory, with 4 slots, a maximum capacity of 256 GB, and an overclocking speed of up to 9200 MHz.
VRM Quality
The MAG B860 Tomahawk WiFi comes with an entry-level VRM setup, delivering 60 A across 12 phases. Works best with CPUs in the ~65–105 W TDP range. Can technically run higher-TDP processors at stock, but will likely experience thermal throttling under sustained heavy loads. Suited for budget gaming, office PCs, and home builds without heavy CPU demands.
See the VRM Appropriate CPU Specification Table at the bottom of this page for recommended CPU options.
Expansion and Storage Overview
The MAG B860 Tomahawk WiFi offers a well-equipped expansion and storage configuration with PCIe 5.0 support, meaning it uses PCI Express 5.0, the newest standard offering extremely high bandwidth for next-generation graphics cards and ultra-fast NVMe storage. It also includes 2 x16 slots , and 1 x1 slot. These PCIe slots are used to connect expansion cards — with the x16 slots typically reserved for graphics cards, while x8, x4, and x1 slots are used for devices like capture cards, sound cards, or network adapters.
For storage, this motherboard provides 3 M.2 slots and 4 SATA ports. M.2 slots are high-speed connectors for modern NVMe SSDs, which are much faster than older storage, while SATA ports are used for traditional hard drives and 2.5-inch SSDs. Together, they allow you to mix fast primary storage with larger, more affordable drives for bulk data.
Connectivity Overview
This motherboard offers solid and reliable connectivity features, including wireless networking with the Wi-Fi 7 standard, and wired Intel® Killer™ E5000 5Gbps LAN ethernet supporting speeds up to 5000 Gbps. Bluetooth 5.4 is available for wireless accessories. It also provides a good selection of modern USB ports to cover most connectivity needs. For exact USB specifications, please see the detailed table.
For video output, this motherboard includes HDMI version 2.1 , DisplayPort version 1.4 , USB-C DisplayPort . These video outputs are intended for integrated graphics and will only function if your CPU includes integrated GPU capabilities.
Audio Quality
The motherboard includes a standard audio chipset (Realtek® ALC897 Codec) that covers basic needs for casual listening. While adequate for everyday use with mainstream headphones or desktop speakers, discerning users may want to add a USB DAC or sound card for improved fidelity, especially for music production or high-end headphones. Additional features include optical S/PDIF output for clean digital audio.
Overall Quality and Value
MAG B860 Tomahawk WiFi is a dependable choice with a respectable overall quality score of 63.80. It provides all the essential features and stable performance expected in a mainstream system, covering typical use cases without unnecessary extras.
This motherboard offers an impressive 75.8% performance-to-price ratio, delivering excellent value by combining strong performance with reasonable cost, making it a smart choice for budget-conscious buyers who don’t want to sacrifice quality.
