ASUS AI Advisor allows users to explore the advanced features and features of ASUS motherboards easily and directly. *

* ASUS AI Advisor availability may vary by region. AI Advisor functions may vary by platform. Digital Power Design

PRIME B850M-A WIFI is equipped with an 8+2+1 phase power design with discrete MOSFETs, which ensures efficient and stable power for AMD processors and consistent performance for daily use. Three M.2 slots (up to 128Gbps)

The PRIME B850M-A WIFI offers a total of three M.2 slots, including one that supports data transfer rates up to 128Gbps via PCIe 5.0 and one supporting PCIe 4.0. This helps speed up application boot and load times with operating system or application drives. *

* Actual transmission speed will be lower than theoretical maximum speed. asus fan xpert 2+

ASUS Fan Xpert 2+ software offers complete fan control. Auto-Tuning mode intelligently configures all parameters with a single click. There is also an Extreme Quiet mode that reduces the speed of the chassis fans below the default minimum to keep the system quiet when performing light tasks. Fans can also be controlled via the UEFI BIOS. Heatsink compatibility

ASUS AIO heatsinks offer robust performance, high overclocking potential, attractive aesthetics, and customizable features for new motherboards, allowing you to build your dream gaming system. Boost your connection

This motherboard offers a versatile range of connectivity, including support for WiFi 6E, PCIe 5.0 slot, and an arsenal of USB ports that include Type-C connections. WiFi 6E

Built-in WiFi 6E* technology leverages the new radio spectrum available in the 6GHz band. With triple the bandwidth of the 2.4/5/6GHz band, WiFi 6E delivers ultra-fast wireless network speeds with improved capacity and better performance in dense wireless environments.

* WiFi 6E availability and features depend on regulatory limitations and coexistence with 5GHz WiFi. Realtek 2.5 gb ethernet

Realtek 2.5Gb Ethernet reduces CPU overhead and delivers exceptionally high TCP and UDP throughput for faster and smoother data transfers. Q-Antenna

With Q-Antenna, connecting a WiFi antenna to your PC is now quick and easy. Instead of slowly turning two fasteners until they lock, they simply snap in. Less trouble and more consistent performance.
