ASUS B850 MAX GAMING WIFI AMD ATX Motherboard DDR5 PCIe 5.0
The ASUS B850 MAX GAMING WIFI is an AMD ATX motherboard built for Ryzen 9000, 8000 and 7000 series processors. It pairs PCIe 5.0 storage support with Wi-Fi 6E connectivity and a robust 8+2+1 phase power design, making it suited to builders who need stable performance for gaming, content creation or AI workloads.
Why this product
PCIe 5.0 M.2 slot for next-gen speed
One M.2 slot runs at up to 128 Gbps via PCIe 5.0 on Ryzen 9000 and 7000 series; two additional PCIe 4.0 slots cover storage expansion.
8+2+1 phase power with discrete MOSFETs
Digital power design ensures stable voltage delivery to the CPU under load, supporting overclocking and sustained performance.
Wi-Fi 6E and 2.5 Gbps Ethernet
Dual connectivity options—wireless and wired—with LANGuard protection on the Ethernet port.
Multiple cooling headers and heatsinks
Four chassis fan headers, CPU and AIO pump headers, plus onboard heatsinks help manage thermals under demanding workloads.
BIOS FlashBack and Aura Sync
Update BIOS without a CPU installed, and sync RGB lighting across three addressable RGB Gen 2 headers.
