Asrock B850 Pro-A WiFi DDR5 ATX Motherboard - Motherboard

ASRock B850 Pro-A WiFi DDR5 ATX Motherboard brings modern AMD AM5 support and Wi‑Fi 6E connectivity to mainstream PC builds with a versatile, feature-rich design.

This ATX motherboard is built around the AMD B850 chipset and supports Socket AM5 processors from the AMD Ryzen 7000, 8000 and 9000 Series, delivering compatibility for current and next‑generation Ryzen CPUs. The UEFI AMI BIOS with 256 Mbit memory ensures smooth setup and reliable firmware updates.

Memory support is strong with four DIMM slots for DDR5‑SDRAM in dual‑channel configuration, supporting up to 256 GB of unbuffered ECC and non‑ECC memory. That makes the board suitable for demanding multitasking, content creation and productivity workloads.

Storage and expansion are flexible: you get four M.2 slots (one PCIe 5.0 x4 and three PCIe 4.0) plus four SATA III connectors, supporting up to eight drives when combined with add‑on devices. The board also offers RAID 0, 1 and 10 support for enhanced performance or redundancy.

Connectivity covers modern needs with Wi‑Fi 6E (802.11ax), Bluetooth 5.2, a 2.5 Gigabit Ethernet port driven by the Dragon RTL8125BG controller, multiple USB ports including USB 3.2 Gen2 Type‑C, and an HDMI 2.1 output supporting up to 3840×2160 resolution. The integrated Realtek ALC897 audio delivers 7.1‑channel sound with multiple analog jacks.

Cooling and system build features are comprehensive: dual CPU fan headers, four chassis fan headers, a dedicated water pump connector, dual 8‑pin EPS power connectors, RGB LED header and TPM connector give builders control and expandability for custom cooling and reliability features.

Use cases for the ASRock B850 Pro‑A WiFi include a high‑performance gaming rig with PCIe 5.0 NVMe storage and discrete GPU, a content creator workstation that benefits from many M.2 slots and ample DDR5 memory capacity, or a home office PC that uses Wi‑Fi 6E and 2.5 GbE for fast networking.

The B850 Pro‑A stands out as a balanced ATX motherboard offering modern connectivity, PCIe 5.0 readiness and robust memory and storage support, making it a strong choice for mainstream to enthusiast AMD AM5 builds.
