Description
MSI PRO B860-P WIFI is an ATX motherboard with an LGA 1851 socket and Intel B860 chipset, aimed at mid-range systems with the option to push it hard for both work and gaming. It supports the latest generation of Intel Core Ultra processors and modern DDR5 memory, so your base is up to date for the next few years. The combination of a PCIe 5.0 x16 slot for the GPU and PCIe 5.0 M.2 for the system SSD gives you a very fast system response and readiness for next-generation graphics cards. The built-in Wi-Fi 7 and 5Gbps LAN handle the networking part without the need for additional cards.
What you get: four DDR5 slots supporting up to 256 GB RAM and frequencies up to 8600 MHz (O.C.) – this means a stable foundation for heavy multitasking, streaming, and productivity without being limited in capacity. The three M.2 slots cover the entire spectrum: from super-fast PCIe 5.0 x4 SSD for OS and games to PCIe 4.0 / SATA M.2 for mass storage, plus another 4 x SATA3 for classic drives or large archives. The expansion PCIe x16 slots allow you to add a capture card, sound card, or other controllers without sacrificing the bandwidth of the main devices. The built-in Wi-Fi 7 and Bluetooth 5.4 save you from cables and dongles, while the 5Gbps LAN is a strong upgrade over the standard 1Gbps for fast local transfers and NAS. The Realtek ALC897 7.1 audio is more than sufficient for everyday gaming, movies, and voice chat without a separate sound card.
- Socket LGA 1851 supporting Intel Core Ultra processors, providing you with an up-to-date platform for the new generation of CPUs.
- Four slots for DDR5 memory, dual-channel mode, and up to 256 GB capacity for serious multitasking, virtual machines, and heavy applications.
- Support for RAM up to 8600 MHz (O.C.), allowing you to squeeze the maximum from fast DDR5 kits for lower latency and better response.
- Three M.2 slots: one PCIe 5.0 x4 from CPU for your fastest system SSD and two PCIe 4.0 x4 / SATA from the chipset for additional fast and flexible storage.
- Four SATA3 6.0 Gb/s ports supporting RAID 0/1/5/10, suitable for arrays balancing speed, capacity, and reliability.
- Main PCIe 5.0 x16 slot for modern GPUs and three more PCIe 4.0 slots for expansion cards, allowing you to configure the system according to your needs.
- Built-in Wi-Fi 7 (802.11be), Bluetooth 5.4, and Realtek 8126 5Gbps LAN, providing fast and flexible connectivity both wired and wirelessly.
- Rich set of USB: up to USB 40Gbps Type-C (Rear), USB 10Gbps, and multiple USB 5Gbps / USB 2.0 ports for all peripherals and external devices.
- Built-in Realtek ALC897 7.1-Channel High Definition Audio for clear sound in games, movies, and voice communication without the need for a separate sound card.
Who it is suitable for: if you are aiming for a modern gaming or workhorse build on the Intel Core Ultra platform with good upgrade potential and plenty of storage, this motherboard is a logical choice. It is also suitable for semi-professional work – video, 3D, dev environments – where a lot of RAM, fast NVMe drives, and strong networking are important. It is not targeted at extreme enthusiasts looking for the highest chipset with maximum overclocking and extras, but for most serious configurations, it provides more than enough.
The combination of LGA 1851, DDR5 up to 256 GB, PCIe 5.0 for GPU and SSD, plus Wi-Fi 7 and 5Gbps LAN makes the MSI PRO B860-P WIFI a very balanced foundation for a modern, fast, and long-term build.
