Best For
- Building a high-performance AMD AM5 system with Ryzen 9000/8000/7000 processors.
- Users requiring Wi-Fi 7 and 5Gbps wired network speeds for online gaming or large file transfers.
- PC builders prioritizing fast storage with multiple PCIe 5.0 M.2 NVMe SSDs.
- Enthusiasts planning to overclock DDR5 memory beyond standard speeds.
Not Recommended For
- Budget-conscious builders who don't need PCIe 5.0 storage or Wi-Fi 7.
- Users who frequently utilize multiple high-bandwidth PCIe devices and M.2 drives simultaneously, due to shared lane limitations.
- Anyone needing full 20Gbps USB-C speeds directly from the rear I/O.
Watch Out For
- The rear USB-C ports only operate at 10 Gbits/s, meaning external devices connected there won't hit the 20 Gbits/s speed available on the internal header.
- If you populate the third PCIe slot and the fourth M.2 slot, they share bandwidth, which can reduce performance for one or both.
- One of the M.2 slots runs at PCIe 4.0 x2, which is half the speed of a full PCIe 4.0 x4 slot and significantly slower than Gen5 slots.
- Activating Wi-Fi 7 and Bluetooth might cause a performance dip in two of the M.2 slots.

What Buyers Say
This B850 Tomahawk MAX WiFi motherboard is getting attention for its robust power delivery and future-ready connectivity, especially for those jumping to AMD's AM5 platform with Ryzen 9000 CPUs. Reviewers frequently point out the strong 14-phase VRM and the inclusion of Wi-Fi 7 and 5Gbps LAN as key selling points. However, some specific limitations like the slower rear USB-C ports and shared bandwidth on certain PCIe/M.2 slots are noted. The DIY-friendly features, such as EZ M.2 clips and a pre-installed I/O shield, also get positive mentions for making builds smoother.
“Dude, this board is a beast for my new Ryzen 9000, the Wi-Fi 7 is legit fast and those Gen5 M.2 slots are insane, but seriously, why is the back USB-C slower than the front? Kinda annoying.”

Buying Guide
When you're picking a motherboard, you're essentially choosing the foundation for your entire PC. It dictates what CPU you can use, how fast your memory can go, and how many high-speed storage drives or expansion cards you can install. Think about your current and future needs for processor power, storage speed, and network connectivity before committing.
Socket AM5
This is the CPU socket type, and it tells you which AMD Ryzen processors are compatible. AM5 is the latest socket for Ryzen 7000, 8000, and 9000 series CPUs, meaning you're getting current-generation processor support.
B850 Chipset
The chipset manages communication between your CPU, memory, and other components. The B850 chipset is a mid-range option that still offers PCIe 5.0 support for graphics and NVMe storage, making it a strong choice for gaming and general high-performance use without the premium cost of an X-series chipset.
PCIe 5.0 x16 and M.2 Gen5
PCIe (Peripheral Component Interconnect Express) is how your graphics card and fast SSDs connect. PCIe 5.0 x16 is the fastest slot for graphics cards, and M.2 Gen5 means your NVMe SSDs can hit incredibly high read/write speeds, significantly reducing game load times and file transfer durations.
Alternatives
If you need more dedicated PCIe lanes for multiple expansion cards or require USB4 support directly from the chipset, look for motherboards with an X870 or X870E chipset. If you're on a tighter budget and don't need PCIe 5.0 storage or Wi-Fi 7, consider B650 chipset motherboards.
