ASRock Pro-A Series B850 Rock-Solid Powerhouse for AM5 Builds
Rock-Solid Powerhouse for AM5 Performance
The ASRock Pro-A Series B850 motherboard is purpose-built for reliability, performance, and user convenience. Designed to serve gamers, creators, and PC builders, it features a rock-solid 14+2+1 phase power delivery system enhanced by 80A Dr.MOS. This ensures consistent power under high loads and provides advanced overclocking headroom. The durable 8-layer PCB design ensures clean signals and thermal stability, giving you the confidence to push modern Ryzenâ„¢ 9000 and 8000 series processors to their limits.
Built for Speed, Stability, and Simplicity
Equipped with next-gen connectivity, the motherboard includes blazing-fast PCIe 5.0 x16 slots, USB 3.2 Gen2x2 Type-C (20Gbps), and the latest Blazing M.2 (Gen5) slot for up to 128Gbps SSD performance. Whether you're installing a high-end GPU or ultra-fast NVMe drives, this platform has the bandwidth and strength to deliver. The integrated Wi-Fi 6E and 2.5G LAN ensure seamless networking, while support for both AMD EXPO™ and Intel® XMP ensures fast, stable DDR5 memory overclocking up to 8000+ MHz.
Pro-Grade Connectivity and Thermal Control
Customization and thermal management are top priorities, with Polychrome RGB lighting headers and multiple fan headers supporting PWM/DC and AIO pump configurations. Setup is simplified by the inclusion of BIOS Flashback, reinforced PCIe slots, and ASRock’s convenient Auto Driver Installer. Whether you’re building your first system or crafting a powerhouse workstation, the ASRock Pro-A Series B850 strikes the perfect balance between performance and practicality.
