I strongly advise against this board and boards from ASROCK. Good configuration: 8 layers, 4 M.2, powerful power supply system. The board kills processors. This board killed my 9600x processor after 8 months of use, warranty was denied. The BIOS is inconvenient.  Evgeniy Yaroshenko: use ASRock B850 Pro RS few months |

Racing Design
The ASRock B850 Pro RS WiFi motherboard belongs to the Race Sport series and stands out with its stylish, dynamic design. The black PCB harmonizes with white heatsinks, geometric patterns, and branded logos, highlighting the premium quality and gaming focus of the device. Massive aluminum heatsinks on key points — the chipset, VRM, and M.2 slots — effectively dissipate heat, preventing components from overheating and throttling. The board already has built-in RGB lighting with ASRock Polychrome Sync effects, which can be customized through the proprietary utility or BIOS to create an individual visual atmosphere.
Elevated Standards
In addition to the standard benefits of the B850 chipset, the manufacturer has implemented modern network technologies: built-in Bluetooth 5.2, Wi-Fi 6E, and 2.5 Gbps LAN modules ensure high bandwidth, stable ping, and maximum compatibility with current routers. The 17-phase power system with Dr.MOS converters guarantees stable voltage and reliable operation of all connected devices. The board is built on an 8-layer structure, which contributes to better current distribution, reduced heating, and prevention of short circuits. This set of features makes the model an excellent choice for assembling an advanced gaming PC based on AMD Ryzen 9 processors, NVIDIA 40 series graphics cards, and high-frequency DDR5 memory. An additional advantage is the USB-C port with a bandwidth of 10 Gbps, DisplayPort support, and the ability to power a monitor.
