ASRock B850 Pro-A WiFi AM5 ATX Motherboard DDR5 Wi-Fi 6E
The ASRock B850 Pro-A WiFi is an AM5 ATX motherboard for Ryzen 9000, 8000 and 7000 series CPUs. It combines PCIe 5.0 expansion, DDR5 memory support, and Wi-Fi 6E connectivity for builders who need high-speed storage, fast networking, and stable power delivery for demanding workloads.
Why this product
PCIe 5.0 and DDR5 support
One PCIe 5.0 x16 slot for graphics and one M.2 PCIe 5.0 x4 socket for NVMe drives. Four DDR5 DIMM slots support memory up to 8000+ MHz (OC).
Wi-Fi 6E and 2.5G LAN
802.11axe Wi-Fi 6E adds a 6GHz band for more capacity and less congestion. Realtek 2.5 Gigabit Ethernet for wired speeds up to 2500 Mb/s.
Robust power delivery
14+2+1 phase power design with 80A Dr.MOS for stable CPU, SoC and miscellaneous power rails.
Multiple M.2 sockets for storage
One PCIe 5.0 x4, two PCIe 4.0 x4, and one PCIe 3.0 x4 M.2 socket, plus four SATA ports for SSDs and mechanical drives.
BIOS Flashback and easy setup
Update BIOS with just a USB drive and power supply—no CPU or RAM required. Pre-installed LAN drivers simplify first-boot setup.

- EAN4711581490192
- Fits all AM5 Ryzen 9000, 8000 and 7000 series CPUs with integrated graphics.
- Accepts standard ATX power supplies with 24-pin and dual 8-pin 12V connectors.
- Works with DDR5 ECC and non-ECC memory modules supporting XMP and EXPO profiles.
- Integrated graphics output via HDMI 2.1 and USB Type-C DP-alt (DP1.4a) requires a CPU with graphics—not available in all Ryzen models.
- PCIe 5.0 bandwidth on M2_1 socket requires a CPU that supports PCIe 5.0; some older AM5 CPUs do not.
Best for
- Builders pairing high-end graphics cards with NVMe Gen 5 drives
- Users who need Wi-Fi 6E and wired Gigabit connectivity on the same board
- Overclocking enthusiasts using DDR5 memory and multiple storage devices
- Content creators and workstation builders requiring stable multi-phase power
Trade-offs
- Builders using older AM5 CPUs that do not support PCIe 5.0 or Wi-Fi 6E features.
- Budget builds where DDR5 memory and PCIe 5.0 SSDs are not yet cost-effective.
- Compact or SFF builds—ATX form factor requires full-size cases with adequate cooling space.
- Users who need more than four SATA connectors; this board offers only four total.
