Product Description
ASRock Lightning B860I Unleash Thunderous Speed and Compact Power
Lightning-Fast Performance Engineering
The ASRock Lightning B860M is engineered to redefine compact performance, delivering peak capabilities in a Mini-ITX form factor. With 10+1+1+1+1 Power Phase and 110A SPS for VCore, GT, and SA, this board offers powerful, reliable, and thermally efficient voltage control for Intel® Core™ Ultra Processors (Series 2). The robust power delivery is complemented by a 10-layer PCB and Hi-Density Power Connectors, ensuring extreme overclocking stability. Paired with DDR5 support for speeds over 9333MHz (OC) and features like Memory OC Shield and XMP/EXPO profiles, this board is built for enthusiasts who want maximum speed in minimal space.
Next-Gen Connectivity & Storage Support
ASRock leaves no stone unturned with future-ready connectivity on the Lightning B860M. You get one Blazing M.2 (Gen5x4) and one Hyper M.2 (Gen4x4) slot for ultra-fast NVMe SSDs, ensuring rapid boot and transfer times. Thunderboltâ„¢ 4 Type-C on both front and rear, Wi-Fi 6E with 802.11axe, Realtek 2.5G LAN, and multiple USB 3.2 Gen2 ports offer premium bandwidth and seamless integration with cutting-edge devices. Whether gaming, streaming, or multitasking, this board enables faster workflows and next-level responsiveness.
Premium Cooling, Audio & DIY Friendly Design
Cooling is no afterthought here—ASRock has integrated a composite VRM heatsink with an aluminum fin array, fan, and heatpipe to ensure top-tier thermal management. The Nahimic Audio system delivers crystal-clear 7.1 channel sound with advanced noise suppression and immersive sound tracking, while RGB lighting via Polychrome RGB and SignalRGB adds personalized flair. Built for system builders, the Lightning B860M includes BIOS Flashback, Auto Driver Installer, and a flexible integrated I/O shield, making it the ultimate Mini-ITX board for serious gamers and creators.
