Description
MSI B860M GAMING PLUS WIFI is a Micro ATX motherboard for the new LGA 1851 socket and Intel Core Ultra processors – a great foundation for a modern mid-range gaming or productivity build. It combines DDR5 memory, PCIe 5.0 for the main PCI-E slot, and three M.2 slots for fast NVMe storage. The built-in Wi-Fi 7 and Intel Killer E5000 5Gbps LAN provide serious networking capabilities right out of the box, without the need for additional cards. You also get a decent set of USB ports, including 10Gbps and Type-C for newer peripherals.
What you get
The LGA 1851 socket and Intel B860 chipset ensure compatibility with the latest generation of Intel Core Ultra, allowing you to upgrade with current CPUs. The four DDR5 slots support up to 256 GB and frequencies up to 8600MHz (O.C.), enabling both stable gaming builds and serious multitasking/production configurations. The three M.2 slots, one of which is PCIe 5.0 x4 directly from the CPU, allow for very fast system SSD plus several additional drives for games and projects. The built-in audio with Realtek ALC897 7.1-Channel HD covers the needs for normal gaming and movies, without needing a separate sound card. The strong networking package – Wi-Fi 7, Bluetooth 5.4, and 5Gbps LAN – makes the board quite flexible for any type of connectivity, from wired low-latency gaming to wireless use in more complex networks.
- LGA 1851 socket supporting Intel Core Ultra processors, providing a platform for the latest generation of Intel CPUs.
- Micro ATX form factor, suitable for more compact cases, without sacrificing the necessary expansion slots and connectors.
- DDR5 memory with 4 slots, up to 256 GB and frequencies up to 8600MHz (O.C.), allowing fast configurations for gaming, streaming, and heavy multitasking.
- Three M.2 slots – 1x PCIe 5.0 x4 from CPU for your fastest SSD and 2x PCIe 4.0 x4 / SATA from the chipset for additional NVMe or SATA devices of various lengths (up to 22110).
- 4 x SATA3 6.0 Gb/s supporting RAID 0/1/5/10, if you want to combine more drives for capacity, speed, or redundancy.
- Main PCI-E x16 slot Gen 5.0 (from CPU) for modern GPUs, plus three more PCI-E 4.0 slots for expansion cards (audio, capture, additional storage).
- High-end networking: Intel Killer E5000 5Gbps LAN for fast wired internet and Wi-Fi 7 (802.11be) + Bluetooth 5.4 for the latest wireless standards.
- Good internal and rear I/O: a total of multiple USB ports, including USB 10Gbps Type A (Rear) and USB 10Gbps Type C (Front) for fast external SSDs and modern devices.
- Power connectors 1 x 24-pin + 2 x 8-pin, providing stable power to the CPU and other components under serious load.
- Built-in 7.1-Channel audio with Realtek ALC897, sufficient for quality sound in games, movies, and voice chat without a separate sound card.
Who it is suitable for
This motherboard is suitable if you want a current Intel platform with LGA 1851 for gaming or a mixed gaming/work build in a more compact case. It is ideal if you plan to use a fast NVMe SSD on PCIe 5.0, strong networking (5Gb LAN + Wi-Fi 7), and enough RAM for streaming, video processing, or many open applications. If you are looking for extreme enthusiast overclocking or an E-ATX system with tons of slots, you might want to look towards higher-end platforms.
The combination of LGA 1851, DDR5, PCIe 5.0, three M.2 slots, and serious networking capabilities makes MSI B860M GAMING PLUS WIFI a very sensible foundation for a modern and long-term gaming or productivity build.
