Description
Asrock B850 Pro-A WiFi AM5 is an ATX motherboard for AM5, aimed at mid-range to serious gaming and productivity builds. It combines a modern AMD B850 chipset with support for Ryzen 9000, 8000, and 7000 Series, so you have options for current and future CPUs. The memory is fully DDR5 with the potential for high frequencies up to 8000MHz (O.C.), which helps for lower latency and better FPS in CPU-limited games. The built-in WiFi 6E, 2.5G LAN, and Bluetooth 5.3 make the board quite complete without the need for additional cards.
What you get
The AM5 socket and AMD B850 chipset provide a stable foundation for a Ryzen build with the option to upgrade to the next generation of processors without changing the board. The four slots for DDR5 with a maximum of 256 GB RAM allow for heavy workloads – virtual machines, compilations, video processing – not just gaming. With four M.2 slots (from PCIe Gen5x4 to Gen3x4), you can separate the system, games, and projects onto separate NVMe drives, without relying solely on SATA. The built-in WiFi 6E and 2.5G LAN provide fast networking both wired and wireless – convenient if the case is far from the router. The audio with Realtek ALC897 7.1-channel HD is more than sufficient for a gaming setup with multi-channel sound, without thinking about a separate sound card.
- CPU socket AM5 supporting Ryzen 9000, 8000, and 7000 Series processors gives you flexibility to choose from more affordable to high-end CPUs.
- DDR5 memory up to 8000MHz (O.C.), with up to 256 GB in 4 DIMM slots, allows for both high FPS in games and heavy multitasking and work.
- Blazing M.2 PCIe Gen5x4 slot for system NVMe provides extremely fast loading of Windows and games, plus additional Gen4x4 and Gen3x4 M.2 for separate libraries and projects.
- PCIe 5.0 x16 slot for graphics card ensures you are ready for current and future high-end GPU models, without the risk of PCIe bottleneck.
- WiFi 6E (802.11ax) and Bluetooth 5.3 eliminate the need for separate adapters for wireless internet and peripherals.
- Dragon RTL8125BG 2.5 Gigabit LAN provides higher bandwidth compared to standard 1G LAN – useful for large files and online gaming.
- 4 x SATA3 6.0 Gb/s with RAID 0/1/10 provide enough space for slower but large drives – archives, libraries, backups.
- Rich panel with USB 3.2 Gen2x2, Gen2, Gen1, and Type-C (rear + front) allows you to connect modern peripherals, fast external SSDs, and case Type-C ports without a shortage of USB.
- 24-pin + 2 x 8-pin power provides stable power delivery to the CPU and system in more powerful configurations.
Who is it suitable for
This motherboard is suitable if you are planning a modern AM5 gaming or productivity build focused on fast NVMe storage and DDR5 memory. It is also suitable for people who want many slots for SSDs and rich network connectivity without additional cards. If you are aiming for a super-cheap budget build or do not need PCIe 5.0 and so many M.2 slots, it may be more than you need.
The combination of AM5, PCIe 5.0 x16, Gen5 M.2, and WiFi 6E makes Asrock B850 Pro-A WiFi AM5 a very solid foundation for a long-term build that you won't be changing anytime soon.
