Description
The ASUS ROG Strix B850-A Gaming WiFi delivers enthusiast-grade features in a striking white ATX design that stands out in any build. Built around AMD's latest B850 chipset for Socket AM5, this board supports the full range of modern Ryzen processors from 7000 through 9000 series. The white aesthetic extends across the board's heatsinks, slots, and connectors, making it an excellent choice for themed builds or anyone wanting something beyond the usual black and grey options.
Storage performance takes center stage with four M.2 slots spread across PCIe generations, including one PCIe 5.0 slot for the fastest NVMe drives available today. Memory support reaches up to 192GB of DDR5 at speeds up to 8000MHz with EXPO profile support, while dual PCIe x16 slots (one Gen 5, one Gen 4) provide flexibility for high-end graphics cards and expansion cards. WiFi 7 connectivity comes built-in with external antennas, eliminating the need for separate wireless adapters.
RGB enthusiasts get three dedicated headers for custom lighting setups that sync with ASUS Aura software, while builders benefit from practical touches like dual 8-pin EPS power connectors for stable power delivery and dedicated water pump headers for liquid cooling systems. The board ships with everything needed for installation including the I/O shield and comprehensive documentation, making it straightforward to get a high-performance AM5 system up and running.
