B850M PRO-A
The Pro-A series is designed for enhanced stability, durability, and performance. It delivers reliable operation, user-friendly features, and a consistent aesthetic, making it ideal for everyday computing.
Optimized for Stability, Durability, and Performance
Combining dependable performance, user-friendly features, and a refined design, it is perfect for daily computing tasks.
Optimized VRM Design
8+2+1 Phase Power Design
Reliable components ensure smooth power delivery to the CPU. They also provide excellent overclocking potential and high performance at lower temperatures for professional gamers.
Dr. MOS
Dr.MOS is an integrated power solution optimized for voltage synchronization across multiple applications. Compared to traditional MOSFETs, it intelligently delivers power to each phase, providing lower operating temperatures and higher performance.
Hi-Density Power Connector
CPU overclocking requires more power. ASRock Hi-Density Power Connectors are designed to handle higher currents than traditional CPU and ATX connectors, ensuring more stable system operation and reducing fire risks during intense overclocking.
6-Layer PCB Design
The 6-layer PCB provides stable signal and power traces, resulting in lower temperatures, higher power efficiency, and reliable operation without compromise.
DDR5 XMP & EXPO Support
Built with stability and reliability in mind, ASRock leaves no detail uncompromised. High-quality materials allow enthusiasts to enjoy increased DDR5 memory overclocking performance with pre-tested profiles. Ensure your memory modules support Intel XMP or AMD EXPO for affordable, satisfying, and hassle-free overclocking.
Fast M.2 Connections
PCIe Gen5 Blazing M.2
This motherboard supports multiple M.2 devices, including PCIe 5.0 M.2 SSDs, offering twice the speed of previous 4th-gen drives for lightning-fast data transfers.
Intelligent Cooling Design
Aluminum Heatsinks
Optimized aluminum heatsinks efficiently dissipate heat during heavy workloads such as gaming or productivity tasks, ensuring system stability and durability.
PWM/DC Fan Support
ASRock fan headers automatically detect DC or PWM fans, allowing precise tuning of fan curves for quieter operation.
Fan-Tastic Tuning
Fan-Tastic Tuning enables automatic detection of each fans minimum load with one click. Users can also easily adjust fan curves via a visual interface, balancing cooling performance and noise reduction.
Dragon LAN 2.5 Gb/s
The 2.5Gb/s LAN ensures maximum network speed for demanding home users, content creators, online gamers, and high-quality streamers. Enjoy 2.5× faster network speeds than standard Gigabit Ethernet for gaming, file transfers, and backups.
Polychrome RGB
Built-in RGB and addressable RGB headers allow connection to compatible LED devices such as strips, CPU fans, coolers, cases, and more. Users can synchronize RGB devices with Polychrome RGB Sync-certified accessories for custom lighting effects.
SignalRGB
SignalRGB unifies RGB devices, providing seamless customization, game-reactive effects, macro automation, and system monitoring. ASRocks official partnership ensures advanced lighting control, wider device compatibility, and greater flexibility.
Dual Graphics Output
Equipped with the most common ports: HDMI + DisplayPort, providing more graphics output options.
Reinforced Steel Slot [PCIe 5.0]
Steel-reinforced PCIe 5.0 slots provide:
- More solder points
- Stronger retention
- Stable signal transfer
- Support for even the heaviest graphics cards
EZ Settings
Auto Driver Installer
No need to worry about missing drives! ASRock pre-installs the LAN driver for easier driver setup than using the SCD disk.
- Step 1: Install Auto Driver Installer
- Step 2: Update required drivers
- Step 3: Done!
BIOS Flashback
Update BIOS with a single click. Users can flash the latest BIOS using a USB drive and power supply, without requiring a CPU, RAM, or other components.
