Základná doska MSI MAG B850 TOMAHAWK MAX WIFI — AMD B850, socket AM5, ATX, DDR5, 4×M.2, Wi-Fi 7, 5Gb LAN, 7.1 Audio

MSI MAG B850 TOMAHAWK MAX WIFI is an ATX motherboard for Socket AM5 that supports AMD Ryzen 7000, 8000 and 9000 series processors. It offers DDR5 memory support up to 256 GB, multiple storage options including M.2 and SATA III, RAID 0/1/10 support, integrated 5 Gigabit Ethernet and Wi‑Fi 7 (802.11be), and a robust power and cooling design intended for stable, long-lasting PC builds.

Advantages

The board features a 14+2+1 Duet Rail Power System with 80A Smart Power Stages and dual power connectors to sustain high-end processors. An optimized PCB and extended heatsinks, including a heavy plated VRM heatsink, enlarged chipset heatsink and M.2 Shield Frozr, improve thermal performance and reliability under heavy loads. High-quality 7W/mK thermal pads and additional choke pads further enhance heat dissipation for stable multi-core operation. Native support for PCIe 5.0, USB 20Gbps and supplemental PCIe power expandability are included for modern components and fast transfer speeds.

Suitable for

• High-performance gaming PC builds with AMD Ryzen Socket AM5 processors
• Content creation and multitasking systems requiring DDR5 memory and fast storage
• Users needing high-bandwidth networking via 5 Gigabit LAN and Wi‑Fi 7
• DIY builders who want robust cooling and power delivery for overclocking or sustained loads

• Chipset: AMD B850
• Processor socket: Socket AM5 (supports Ryzen 7000/8000/9000 series)
• Memory: DDR5, 4 slots, up to 256 GB
• Storage interfaces: M.2 (with M.2 Shield Frozr), SATA III
• Expansion: PCIe 5.0 support, PCIe x16 slot(s)
• Power design: 14+2+1 Duet Rail Power System, 80A Smart Power Stage
• Networking: 5 Gigabit Ethernet and Wi‑Fi 7 (802.11be)

How to use

Install the motherboard into a compatible ATX case and connect an AM5-compatible AMD Ryzen processor, DDR5 memory modules (up to four), storage devices (M.2 and SATA), and the required PSU connectors including the dual CPU power inputs. Attach cooling solutions to the provided VRM and chipset heatsinks where applicable. Configure BIOS settings for memory profiles, storage RAID levels (0/1/10) and network preferences. Install the operating system and drivers from MSI to ensure full functionality of onboard features.

Recommendations

For stable performance under sustained heavy loads, use high-quality cooling for the CPU and ensure adequate case airflow to help the extended heatsinks and M.2 Shield Frozr maintain optimal temperatures. When using high-power processors, connect both CPU power connectors and verify BIOS is updated to the latest version for full Ryzen 9000 series support.
