ASRock Lightning B860M Unleash Next-Gen Speed and Style

Lightning-Inspired Performance Architecture
The ASRock Lightning B860M delivers a visually striking and high-performance motherboard built for gamers, creators, and professionals. Inspired by the raw speed and energy of lightning, its sharp lines and angular design reflect the powerful internal components. Supporting Intel® Core™ Ultra Processors (Series 2) on the LGA1851 socket, it features a robust 12+1+1+1+1 power phase design, 80A SPS for clean power delivery, and Hi-Density connectors for enhanced durability. With support for up to 256GB of DDR5 memory overclocked to 8666+ MHz and a reinforced PCIe 5.0 x16 slot, this board is engineered for future-ready computing.
Next-Level Connectivity and Expansion
Equipped with a premium suite of high-speed interfaces, the Lightning B860M ensures lightning-fast data transfer and seamless connectivity. Thunderbolt™ 4, Wi-Fi 6E, and Killer 2.5G LAN offer ultra-responsive networking and peripheral support. With four blazing-fast M.2 slots—including one PCIe Gen5 and three PCIe Gen4—and four SATA3 ports, storage expansion is effortless and versatile. USB 3.2 Gen2, USB 2.0, and a front Type-C header cover all your connectivity needs, while the built-in Nahimic audio provides immersive sound for gaming and media.

Built for Overclockers and DIY Enthusiasts
From its advanced power phases and Memory OC Shield to the enlarged tool-less M.2 heatsinks and reinforced steel PCIe slot, the Lightning B860M is designed with enthusiasts in mind. Fan-Fantastic Tuning, thermistor headers, and a pre-installed I/O shield ensure excellent thermal control and build convenience. With support for BIOS Flashback and SignalRGB for system lighting, it empowers users to push performance boundaries while personalizing their setup. Whether you're overclocking or fine-tuning your rig, this board delivers elite-class tools in a micro ATX form factor.
