Placa-mãe ASRock B860 Pro-A — Intel B860 ATX, LGA 1851, DDR5, 4x DIMM, 256GB, LAN 2.5Gb, 1x M.2, 4x SATA III

Pro-A series is designed for enhanced stability, durability, and efficiency, offering reliable performance, user-friendly features and a streamlined aesthetic suitable for daily computing tasks. The motherboard includes advanced power delivery, DDR5 memory support, PCIe Gen5 M.2 storage, onboard networking up to 2.5 Gb/s and customizable RGB options to meet modern PC needs.

Advantages

The board uses a 10+1+1 power phase design with Dr.MOS for smooth and efficient CPU power delivery, supporting higher currents and improved thermal performance. Hi-density power connectors increase stability during heavy CPU overclocking. Integrated aluminum heatsinks help maintain lower temperatures under load, while a reinforced steel PCIe slot supports heavy graphics cards. Built-in 2.5 Gb/s LAN improves network bandwidth and onboard RGB headers plus SignalRGB and Polychrome RGB support enable unified lighting control across compatible devices.

Key specifications

• Power design: 10+1+1 power phases with Dr.MOS
• Power connectors: Hi-Density CPU and ATX power connectors
• Memory: DDR5 with Intel XMP / AMD EXPO profile support
• Storage: PCIe Gen5 Blazing M.2 (up to 128 Gb/s)
• Cooling: Optimized aluminum heatsink design
• LAN: Dragon 2.5 Gb/s Ethernet
• PCIe slot: Reinforced steel slot (PCIe 5.0 compatible)
• RGB: Onboard RGB and addressable RGB headers, Polychrome RGB, SignalRGB support

How to use

Install the motherboard into your case following the manufacturer’s manual, connect the hi-density CPU and ATX power connectors, insert DDR5 memory modules that support Intel XMP or AMD EXPO if you plan to use pre-tested overclocking profiles, and mount an M.2 PCIe Gen5 SSD into the Blazing M.2 slot. Attach cooling solutions to the aluminum heatsinks and connect RGB devices to the appropriate headers. Configure BIOS settings for power phases, memory XMP/EXPO profiles and storage boot order, and install SignalRGB or Polychrome RGB software to synchronize lighting.

Recommendations

For stable overclocking and long-term reliability, use quality high-current power supplies, certified DDR5 modules with XMP/EXPO support, and ensure proper case airflow. Verify compatible PCIe Gen5 SSDs and heavy GPU mounting with the reinforced steel slot for secure installation.
