Description for: MSI MAG B850 Tomahawk Max WiFi – AM5 ATX Motherboard
AM5 · B850 · ATX
Build a focused single-GPU workstation.
A DDR5 AM5 motherboard with a CPU-connected PCIe 5.0 x16 slot, 5Gb Ethernet and Wi-Fi 7 for a practical Ryzen workstation.
PCIe 5.0 x16 · 5Gb LAN · Four M.2 slots
Where it fits
A practical foundation for development, content creation and a workstation centred on one dedicated AI GPU. Four M.2 slots offer storage flexibility, while 5Gb Ethernet supports a faster wired connection to compatible networking equipment.
Compatibility before checkout
Supports Ryzen 9000, 8000 and 7000 series subject to the MSI CPU-support list and BIOS. Use supported non-ECC unbuffered DDR5; DDR4 and registered server RDIMMs are not substitutes. This is not a board with three electrically x16 GPU connections.
Expansion and bandwidth explained
For Ryzen 9000/7000, PCI_E1 is PCIe 5.0 x16. PCI_E2 is chipset PCIe 3.0 x1 despite its full-length connector. PCI_E3 is chipset PCIe 4.0 x4, reduced to x2 when M2_3 is used. Selecting PCI_E3 x4 in BIOS disables M2_3. Ryzen 8000 processors reduce the primary slot generation and lane width; check the MSI specification table.

Frequently asked questions
Are all three long slots x16 electrically?
No. With Ryzen 9000/7000, the primary slot is x16, the middle slot is x1 and the lower slot is up to x4 with M.2 sharing.
Can I populate every M.2 slot without changing PCIe bandwidth?
M2_3 shares resources with PCI_E3. With M2_3 populated, PCI_E3 operates at x2; forcing PCI_E3 x4 disables M2_3.
Is Wi-Fi 7 available on every operating system?
Features depend on the OS and local regulations. MSI specifies Windows 11 24H2 for Wi-Fi 7 readiness.
