More details

ASUS PRIME B860M-K — a compact Micro ATX foundation for Intel Core Ultra processors (Series 2): DDR5 up to 8800+ MT/s (OC) with AEMP III, PCIe 5.0 M.2 storage up to 128Gbps, Realtek 2.5Gb Ethernet, USB 10Gbps, and a 6+1+1+1 digital power design — expertly engineered to unleash the full potential of Core Ultra in a space-saving 24.4cm footprint, with Advanced AI PC-ready power and connectivity.

Built for Intel Core Ultra Processors (Series 2)

The PRIME B860M-K supports Intel Core Ultra processors (Series 2) on the Intel B860 chipset, with a 6+1+1+1 phase digital power design featuring discrete MOSFETs that ensures efficient and stable power delivery for Intel processors plus steady performance for day-to-day use. A ProCool 8-pin connector improves the PSU connection, Digi+ VRM control delivers real-time voltage management, and Power Saving optimizes CPU, lighting and fan settings.

AEMP III for Ultimate DDR5 Performance

Two DDR5 DIMM slots support up to 96GB at up to 8800+ MT/s (OC) with Intel XMP and Clocked Unbuffered DIMM (CUDIMM) support. ASUS Enhanced Memory Profile III (AEMP III) empowers unparalleled memory performance with cutting-edge CUDIMM through a two-phase comprehensive tuning process — optimizing the clock driver first, then the memory frequency — delivering up to 19% faster speeds than baseline DDR5, even at cutting-edge speeds of DDR5-7600 or higher. DIMM Fit precisely analyzes individual memory modules to optimize performance and pinpoint potential issues, with DIMM Fit Pro providing advanced builders up to twenty overclocking parameters.

Memory & Storage Performance

Two M.2 slots deliver quick boot-up and app load times: one PCIe 5.0 x4 slot supporting up to 128Gbps and one PCIe 4.0 x4 slot at 64Gbps, alongside four SATA 6Gb/s ports with Intel Rapid Storage Technology RAID 0/1/5/10. The PCIe 4.0 x16 slot with SafeSlot Core+ handles modern graphics cards, with two PCIe 4.0 x1 slots for expansion cards.

ASUS AI Solutions & Cooling

ASUS AI Advisor is your technical expert with expertise in PC performance, letting you explore the functionality and advanced features of your motherboard using natural language. The board is engineered with multiple onboard heatsinks and hybrid fan headers to keep your rig cool and stable under intense workloads: VRM heatsinks with thermal pads, a passive chipset heatsink and multiple temperature sources, with ASUS Fan Xpert 2+ software providing one-click Auto-Tuning and Extreme Quiet modes also available via the UEFI BIOS.

Empowering Connections

Realtek 2.5Gb Ethernet with ASUS LANGuard reduces CPU overhead and offers exceptionally high TCP and UDP throughput for faster, smoother data transfers. The rear panel offers a USB 10Gbps port, two USB 5Gbps ports and three USB 2.0 ports, plus a PS/2 combo connector for legacy peripherals, with a front-panel USB 5Gbps Type-C connector adding case connectivity. DisplayPort 1.4 (4K@60Hz) and HDMI 2.1 (4K@60Hz) cover monitor output, and Realtek 7.1 HD audio with premium capacitors, audio shielding and dedicated audio PCB layers delivers quality sound.

EZ PC DIY & Customization

SafeSlot Core+ is a one-piece stainless-steel brace that shields the slot and anchors it to the PCB with strengthened solder points, providing a secure foundation for heavyweight graphics cards. Q-LED Core diagnostics confirm components are functioning at startup, Q-Dashboard simplifies BIOS navigation, and ASUS 5X Protection III provides DIGI+ VRM, LANGuard, overvoltage protection and a stainless-steel back I/O. Two Addressable Gen 2 headers plus an Aura RGB header with Aura Sync deliver complete RGB lighting control, while Armoury Crate and ASUS DriverHub round out the software suite.
