Verdict

The Gigabyte B860M K is a budget-focused Micro-ATX motherboard designed for Intel Core Ultra (Series 2) processors on the LGA 1851 socket. It features a hybrid 4+1+2 phase VRM solution for stable power delivery and supports dual-channel DDR5 memory with overclocked speeds up to 8800 MT/s across two DIMM slots (up to 128GB). Storage and expansion are handled by two PCIe 4.0 x4 M.2 slots, four SATA 6Gb/s ports, and a primary PCIe 4.0 x16 slot with an EZ-Latch quick-release design. Connectivity includes a 1GbE Realtek LAN, HDMI 2.1 supporting 4K at 60Hz, and multiple USB 3.2 Gen 1 ports. Its main pros are the AI-driven performance optimizations like AI PerfDrive and the user-friendly BIOS with 'Quick Access' functions, providing a solid entry point for next-gen builds. However, notable cons include the lack of integrated Wi-Fi or Bluetooth, the absence of PCIe 5.0 support on the main x16 slot, and a limited number of memory slots and fan headers compared to higher-tier B860 models.
