ASRock B860M-X Intel B860 Micro ATX Motherboard

The ASRock B860M-X delivers reliable performance for Intel Core Ultra Processors (Series 2) in a compact Micro ATX form factor. Designed for users seeking a balanced combination of modern features and value, this LGA1851 motherboard supports the latest DDR5 memory technology and PCIe 5.0 storage solutions.

Intel LGA1851 Socket with Robust Power Delivery

Built around the Intel B860 chipset, this motherboard features a 7+1+1+1+1 power phase design that ensures stable power delivery to Intel Core Ultra Series 2 processors. The 6-layer PCB construction provides enhanced signal integrity and improved thermal management, allowing for consistent performance during demanding workloads.

DDR5 Memory Support with Overclocking

Two DDR5 DIMM slots support dual-channel memory configurations up to 128GB, with speeds reaching 9066MHz+ when overclocked. XMP 3.0 and EXPO profiles enable one-click memory optimization, making it simple to extract maximum performance from compatible memory modules without manual tuning.

Next-Generation Storage Connectivity

The B860M-X includes one PCIe Gen5 x4 M.2 slot (Blazing M.2) capable of 128GB/s transfer speeds, future-proofing your system for upcoming ultra-fast SSDs. A second M.2 slot supports PCIe Gen4 x4 drives, while four SATA III ports accommodate traditional storage devices. RAID 0, 1, 5, and 10 configurations are supported across SATA devices.

Expansion and Graphics Options

Expansion capabilities include one PCIe 4.0 x16 slot for discrete graphics cards, one PCIe 4.0 x4 slot, and one PCIe 4.0 x1 slot. Integrated graphics output through HDMI and DisplayPort 1.4 connections support multi-monitor setups when using processors with integrated graphics. The Realtek ALC897 audio codec delivers 7.1-channel HD audio.

High-Speed Networking and USB Connectivity

Realtek 2.5G LAN provides 2.5X the bandwidth of standard gigabit Ethernet, ideal for content creators, gamers, and media streaming. USB connectivity includes one USB 3.2 Gen2x2 Type-C port (20Gbps) on the rear panel, plus multiple USB 3.2 Gen1 and USB 2.0 ports across front and rear I/O. Front panel Type-C support adds modern case compatibility.

Thermal Management and Cooling

Aluminum heatsinks dissipate heat from critical components during intensive tasks. Multiple fan headers support both PWM and DC modes, with automatic detection and customizable fan curves through ASRock's A-Tuning software. The Fan-Tastic Tuning function auto-detects minimum fan duty cycles for optimized cooling and noise levels.

User-Friendly Features

BIOS Flashback functionality allows BIOS updates using only a USB drive and power supply—no CPU or RAM required. Auto Driver Installer pre-loads LAN drivers for streamlined setup. Polychrome RGB headers and addressable RGB support enable customization with compatible LED devices, with SignalRGB integration for advanced lighting control.

The ASRock B860M-X combines essential modern features with practical functionality, making it suitable for mainstream builds requiring Intel Core Ultra Series 2 processor support, DDR5 memory, and PCIe 5.0 storage readiness.
