Description
MSI B860 GAMING PLUS WIFI LGA1851 is an ATX motherboard for the new generation of Intel Core Ultra processors on the LGA 1851 socket, aimed at mid-range gaming and serious all-round builds. It combines a modern Intel B860 chipset, fast DDR5 support, and a rich set of M.2 and PCIe slots, so you won't have to think about upgrading soon. The built-in Wi-Fi 7, 5Gbps LAN, and USB 40Gbps Type-C free you from the need for additional cards and dongles. You get a balanced platform for gaming, work, and everyday use with a focus on connectivity and expandability.
What you get
The LGA 1851 socket and support for Intel Core Ultra processors give you access to the latest generation of Intel CPUs, suitable for both gaming and productivity. The four slots for DDR5 memory with a capacity of up to 256 GB and frequencies up to 8600 MHz (O.C.) allow for serious RAM upgrades – from a typical gaming build with 32 GB to heavy workstation loads. The three M.2 slots supporting up to PCIe 5.0 x4 from the CPU and PCIe 4.0 / SATA from the chipset allow you to combine a super-fast system NVMe for OS and large SSDs for games or projects. The built-in Wi-Fi 7 and Intel Killer E5000 5Gbps LAN mean that whether you are wired or wireless, the network won't be a bottleneck. And with Realtek ALC897 7.1 audio, you can build a decent gaming or multimedia system without a separate sound card.
- LGA 1851 socket supporting Intel Core Ultra processors, so you can step onto the current Intel platform with the possibility of future updates.
- ATX form factor, which provides enough space for multiple PCIe cards, M.2 SSDs, and more serious cooling in standard mid/full tower cases.
- DDR5 memory with up to 4 slots, maximum 256 GB and frequencies up to 8600 MHz (O.C.), suitable for high-refresh gaming, streaming, and heavy applications that perform well from fast RAM.
- 3x M.2 slots, including one from the CPU with up to PCIe 5.0 x4 for your fastest NVMe, plus two from the chipset with PCIe 4.0 x4 / SATA for a flexible combination of speed and capacity.
- 4 x PCI-E x16 slots with the main PCIe 5.0 x16 for modern GPUs, and additional PCIe 4.0 slots for capture cards, network adapters, or other expansions.
- Wi‑Fi 7 (802.11be) and Bluetooth 5.4, which save you the need for additional adapters and provide future-ready wireless connectivity.
- Intel Killer E5000 5Gbps LAN for higher bandwidth than standard 1Gbps LAN – plus stable wired internet for multiplayer, streaming, and file transfers.
- 4 x SATA3 with support for RAID 0/1/5/10, if you want to combine classic SSD/HDD arrays for security or more throughput.
- Rich USB set: from USB 2.0 for peripherals to USB 10Gbps and USB 40Gbps Type-C for fast external drives, docking stations, and modern devices.
- Realtek ALC897 7.1-Channel HD Audio for decent surround sound in games and movies without immediately investing in a separate sound card.
Who it is suitable for
This board is suitable for gamers planning a build with Intel Core Ultra, a modern PCIe 5.0 x16 graphics card, and several fast NVMe drives – 1080p/1440p gaming, streaming, and content creation. It is also convenient for power users with many peripherals and external devices who will appreciate USB 40Gbps and 5Gbps LAN. It is not aimed at ultra-budget systems, nor at extreme overclocking maniacs, but rather at a balanced, long-term mid/high-range build.
The combination of LGA1851, PCIe 5.0 x16, fast DDR5 support, and modern network connectivity (Wi‑Fi 7 + 5Gbps LAN + USB 40Gbps) makes MSI B860 GAMING PLUS WIFI a stable foundation for a current and future system. If you are looking for a motherboard that “does everything” without unnecessary extras and embellishments, this is a very sensible choice.
