ASRock B850 Pro RS WiFi AM5 ATX Motherboard - DDR5, Wi-Fi 6E
The ASRock B850 Pro RS WiFi AM5 ATX Motherboard is built for users running AMD Ryzen 7000, 8000 or 9000 series processors who want modern connectivity, fast storage expansion and reliable daily performance. It combines DDR5 memory support, WiFi 6E, PCIe 5.0 storage and 2.5G networking in a stable, efficient platform designed for both standard computing and overclocking.
Why this product
WiFi 6E with 6GHz band
The 802.11axe WiFi 6E module extends into the 6GHz spectrum, delivering lower latency and higher throughput than WiFi 6. Dual-band 2x2 design supports dual frequencies simultaneously.
PCIe 5.0 and DDR5 ready
One Blazing M.2 slot runs PCIe Gen5x4 for the fastest NVMe drives available. DDR5 support scales to 8000+ MHz (OC) across four DIMM slots, with XMP and EXPO profiling for straightforward tuning.
2.5G LAN with adaptive software
Realtek Dragon RTL8125BG controller delivers 2.5 Gbps wired speed. ASRock's Dragon software lets you prioritise traffic by mode—Game, Browser, or Streaming—and monitor usage in real time.
Eight-layer PCB for stability
Thicker, more stable signal routing reduces electromagnetic noise and heat generation, particularly beneficial during memory overclocking. Power delivery uses 14+2+1 phases with 80A Dr.MOS.
Extensive USB and M.2 expansion
Includes four M.2 slots (Gen5, Gen4, Gen4, Gen3), four SATA ports, USB 3.2 Gen2x2 Type-C front header, and a total of 10 USB 3.x ports plus 10 USB 2.0 connectors on rear and front headers.

- SKUASR-2022
- EAN4711581490178
- Supports all AMD Ryzen 9000, 8000 and 7000 series processors in Socket AM5.
- Accepts DDR5 memory modules, both ECC and non-ECC, up to 256 GB total capacity.
- Fits standard ATX case mounting (305 mm × 244 mm).
- DisplayPort output requires USB Type-C, not HDMI; only the HDMI port outputs directly without DP Alt Mode.
Best for
- Builders upgrading from DDR4 or WiFi 5 who want modern connectivity without overspecifying.
- Users running multiple high-speed NVMe drives; four M.2 slots with mixed PCIe generations accommodate a range of storage needs.
- Network-conscious users; 2.5G LAN and WiFi 6E with software traffic control suit content creators and gamers who care about bandwidth allocation.
- Memory overclockers; eight-layer PCB and 14+2+1 power delivery provide stable electrical environment for high-frequency DDR5 tuning.
Trade-offs
- Budget builders; this board includes WiFi 6E and 2.5G LAN as standard, raising cost versus basic B850 variants.
- Users needing legacy SATA-only storage; only two SATA3 ports integrated on-board, with two more routed through a separate controller.
- Workstations requiring multiple simultaneous USB-C peripherals; rear I/O includes only two USB Type-C ports total.
Modern and futuristic, with the attractive specifications and perfect balance, the Race Sport (RS) Edition is the evolution of the most popular PRO series motherboard.
Optimized for stability, durability, and efficiency. It combines reliable performance, user-friendly features and streamlined style for daily computing tasks.
The 8 Layer PCB provides stable signal traces and power shapes delivering lower temperature and higher energy efficiency for memory overclocking! Thus, it's able to support the latest memory modules with most extreme memory performance!
WiFi 6E technology has extended to the whole new 6GHz spectrum band, providing more WiFi capability and giving an even better and faster internet traffic. In addition to deliver higher speeds, the WiFi 6E also enhances the lower latency and supports service levels that are equivalent to 5G networks.
The latest USB 3.2 Gen2x2 Type-C delivers up to 20 Gbps data transfer rate which is 2x as fast as previous generation, providing a blazing fast data transfer interface with reversible USB Type-C design that fits the connector either way. USB Alternate Mode allows USB Type-C ports to provide power, transfer data, and output display signals to DisplayPort monitors through a single cable.
