Your AMD Ryzen Build Starts Here
The ASRock B850 Pro-A Wi-Fi gives your AMD Ryzen™ 9000, 8000, or 7000 series processor the platform it deserves — a rock-solid ATX foundation with the headroom to grow. Whether you’re assembling a high-performance gaming rig or a capable workstation, this board delivers the stability and compatibility to bring your build to life.
Blazing Storage, Zero Bottlenecks
With a PCIe Gen5 M.2 slot pushing up to 128 Gb/s and three additional high-speed M.2 slots, your SSDs will never be the thing holding you back. Pair that with four SATA3 ports and RAID support, and you have a storage setup ready for anything from massive game libraries to professional workloads.
Connected Without Compromise
Wi-Fi 6E and 2.5G LAN keep you wired and wireless at the fastest speeds available, while a generous spread of USB ports — including USB 3.2 Gen2x2 Type-C — means your peripherals, displays, and external drives all have a home. HDMI 2.1 and USB-C DisplayPort output round out a connectivity suite built for modern multi-monitor setups.
RGB, Fan Control & Future-Ready BIOS
Dial in your aesthetics with Polychrome SYNC RGB headers and addressable LED support, while Smart Fan Speed Control keeps thermals in check across all your fans and AIO pump. BIOS Flashback means you can update firmware without even needing a CPU installed — making this board as builder-friendly as it is powerful.
