GIGABYTE B860M H DDR5 Motherboard with Intel B860 Express Chipset

The GIGABYTE B860M H is a capable micro-ATX LGA1851 motherboard built on the Intel B860 chipset, ideal for compact Intel Core Ultra and 14th-Gen systems. It supports DDR5 memory up to 8800 MT/s (overclocked) in dual-channel mode and offers robust expansion with a PCIe 5.0 x16 slot for modern graphics cards and a PCIe 4.0 x1 slot for add-in cards. Storage includes two M.2 PCIe 4.0 slots and four SATA 6 Gb/s ports. Networking is handled by 2.5 GbE LAN, while integrated HDMI provides display output. Builder-friendly features like EZ-Latch PCIe, advanced cooling headers, Smart Fan 6, and user-friendly BIOS make it a solid choice for both gaming and productivity builds.
