Asrock B850M PRO-A Built for Power, Ready for Tomorrow

Performance, Power, and Reliability
The ASRock B850M PRO-A is engineered to deliver stable, efficient, and high-end performance for the latest AMD Ryzen 9000, 8000, and 7000 Series processors. With its 8+2+1 Phase Power Design, Dr.MOS modules, and Hi-Density Power Connectors, this board offers consistent voltage regulation, excellent thermal management, and durability—even under heavy workloads and overclocking. A 6-layer PCB adds extra stability and thermal efficiency, while DDR5 support with XMP & EXPO profiles lets users overclock memory effortlessly for enhanced system responsiveness and speed.
Next-Gen Connectivity and Storage
Optimized for high-speed access and future-proof setups, the B850M PRO-A features 1x Blazing M.2 PCIe Gen5x4 slot, 2x Hyper M.2 PCIe Gen4x4 slots, and 4 SATA3 ports. Whether you’re a gamer, a power user, or a creator, these blazing-fast storage options offer ultra-low latency and rapid data transfers. USB 3.2 Gen2 Type-C and Type-A ports (both front and rear) provide quick access for modern peripherals, while Realtek 2.5G LAN ensures seamless online connectivity for downloads, gaming, and streaming.

Custom Cooling, RGB, and Easy Setup
Thermal performance is strengthened through optimized aluminum heatsinks and customizable PWM/DC fan headers, including ASRock’s Fan-Tastic Tuning for complete fan curve control. Personalize your setup with Polychrome RGB and SignalRGB integration, offering full sync and lighting customization across compatible components. Additionally, Auto Driver Installer and BIOS Flashback features make it simple to get your system up and running without the need for a CPU or memory—ensuring maximum convenience for builders and upgraders alike.
