ASRock B860M-X Micro ATX DDR5 Motherboard (PCIe 5 and Wi-Fi 6E)

For system builders who want performance without the bulk, the ASRock X-Series Micro ATX DDR5 Motherboard with PCIe Gen5 & Wi-Fi 6E stands out as a compact powerhouse engineered for serious productivity. It’s designed to support the latest Intel® Core™ Ultra Series 2 CPUs on the LGA1851 socket, combining next-gen processing with high-speed memory and lightning-fast connectivity.

The Micro ATX form factor makes it ideal for compact setups, but there’s nothing small about what it delivers. Dual DDR5 DIMM slots support up to 128GB with overclocking speeds north of 9066MHz. This level of headroom means smoother multitasking, faster compile times, and more responsive virtualisation—especially useful for professionals working across demanding workflows.

Storage is handled with equal ambition: a blazing PCIe Gen5 M.2 slot on the CPU lane delivers up to 128Gb/s, complemented by Gen4 M.2 and four SATA ports with RAID support. Visual output is equally robust, with support for 4K 120Hz via HDMI 2.1 and up to 8K 60Hz through DisplayPort 1.4, ideal for content creators and multi-monitor users.

Networking and I/O are where the board quietly excels. You get 2.5GbE LAN with smart bandwidth controls and Wi-Fi 6E for reliable wireless throughput—even in congested environments. Add BIOS Flashback, driver-free installation, and ASRock’s signalRGB lighting control, and you’ve got a board that’s as functional as it is forward-looking.

This is more than just a Micro ATX DDR5 motherboard with PCIe Gen5—it’s a strategic backbone for professionals who demand desktop-grade stability in a smaller footprint. If versatility, speed, and build efficiency matter, this board deserves a serious look.
