ASRock B860I Lightning WiFi Mini ITX Motherboard

The ASRock B860I Lightning WiFi delivers high-performance computing in a compact Mini ITX form factor. Built for Intel Core Ultra Processors (Series 2) with LGA1851 socket, this motherboard combines power efficiency with advanced connectivity features for gaming and productivity builds.

Power Delivery and Performance

Engineered with a robust 10+1+1+1+1 power phase design featuring 110A Smart Power Stage (SPS) for VCore+GT+SA, the B860I Lightning WiFi ensures stable power delivery during intensive workloads and overclocking. The 10-layer PCB construction provides superior signal integrity and thermal management, while Dr.MOS technology optimizes current delivery to each phase for enhanced efficiency.

Support for dual-channel DDR5 memory up to 9333MHz (OC) with Intel XMP profiles allows users to maximize system performance. The exclusive Memory OC Shield reduces electromagnetic interference, ensuring stable operation at higher frequencies. Two DDR5 DIMM slots accommodate up to 128GB of memory.

High-Speed Storage and Connectivity

The motherboard features two M.2 slots: one Blazing M.2 with PCIe Gen5 x4 support delivering 128Gb/s transfer speeds, and one Hyper M.2 with PCIe Gen4 x4 capability. Three SATA III ports provide additional storage expansion. The single PCIe 5.0 x16 slot with reinforced steel construction supports the latest graphics cards.

Thunderbolt 4 Type-C connectivity offers 40Gbps data transfer, display output, and device charging through a single cable. USB options include 2x USB 3.2 Gen2 Type-A, 6x USB 3.2 Gen1, and 3x USB 2.0 ports across front and rear I/O.

Network and Wireless

Realtek 2.5G LAN provides 2.5X the bandwidth of standard gigabit Ethernet with intelligent traffic prioritization for gaming. Wi-Fi 6E 802.11axe module extends coverage to the 6GHz spectrum band with dual-band 2x2 160MHz support and Bluetooth 5.3 connectivity.

Audio and Cooling

Realtek ALC1220 7.1 CH HD audio codec paired with Nahimic Audio software delivers immersive sound with noise cancellation and Sound Tracker positioning. The composite VRM heatsink combines aluminum construction with heat pipe technology for efficient thermal dissipation. PWM/DC fan headers with automatic detection and thermistor monitoring enable customized cooling profiles through Fan-Tastic Tuning software.

User-Friendly Features

BIOS Flashback allows firmware updates using only a USB drive and power supply—no CPU or RAM required. The flexible integrated I/O shield adjusts during installation for perfect chassis fitment. Polychrome RGB and addressable RGB headers with SignalRGB support enable synchronized lighting effects across compatible devices. Auto Driver Installer with pre-installed LAN driver simplifies system setup.
