–

The MSI PRO B860M-A WIFI is a micro-ATX (mATX) motherboard designed for users seeking a compact yet capable platform for Intel’s latest Core Ultra Processors (Series 2). It prioritizes stability and reliability while offering a good selection of features and connectivity options in a smaller form factor.

CPU and Chipset Support

The motherboard is built around the Intel B860 chipset, providing a stable foundation for Intel’s Core Ultra Processors (Series 2). It supports the entire range of these processors, ensuring compatibility with the latest and most powerful CPUs in this series. The LGA 1851 socket design ensures compatibility with future Intel CPUs within the Series 2 lineup, making it a future-proof investment.

Memory Support

The PRO B860M-A WIFI features two DDR5 DIMM slots, supporting up to 64GB of DDR5 RAM in a dual-channel configuration for optimal performance. Supported memory speeds range from standard JEDEC speeds up to impressive overclocked speeds of 7600+ MHz (depending on the specific CPU and memory modules used). While overclocking capabilities might be slightly more limited than larger ATX motherboards, it still allows for performance tuning. The motherboard supports Intel XMP 3.0 profiles for streamlined memory overclocking and optimized performance profiles.

Storage and Expansion

Despite its compact size, the PRO B860M-A WIFI offers a good selection of storage options. It includes two M.2 slots, both supporting PCIe 4.0 x4 speeds for high-speed NVMe SSDs. This provides ample space for fast boot times and significantly improved load times for games and applications. In addition to the M.2 slots, the motherboard includes four SATA 6Gbps ports for traditional SATA-based storage devices, offering flexibility for various storage needs [1][2][4]. Expansion capabilities are present, although limited by the mATX form factor, featuring one PCIe 5.0 x16 slot for a graphics card, and one PCIe 3.0 x1 slot for additional expansion cards.

Networking and Wireless Connectivity

The PRO B860M-A WIFI provides comprehensive networking capabilities, integrating both wired and wireless connectivity. It includes a 2.5G LAN port powered by the Intel I225-V controller, offering faster wired network speeds than standard Gigabit Ethernet. Wireless connectivity is handled by an integrated Intel Wi-Fi 6E solution, supporting the Wi-Fi 6E standard with speeds up to 2.4Gbps. This ensures fast and reliable wireless networking, ideal for online gaming, streaming, and other bandwidth-intensive tasks. Bluetooth 5.2 is also integrated for seamless wireless peripheral connectivity.

Connectivity and USB Ports

The motherboard offers a selection of USB ports, though the number is reduced compared to larger ATX boards due to the mATX form factor. It includes several USB 3.2 Gen 2 ports offering speeds up to 10Gbps, along with USB 2.0 ports for backward compatibility. The rear panel includes a USB Type-C port and USB Type-A ports for convenient high-speed connectivity. Video output options are provided through the HDMI 2.1 connector, supporting high-resolution displays.

Power Delivery and Cooling

The PRO B860M-A WIFI features a power delivery system designed for stability and reliability, although details on the specific phase configuration may not be explicitly stated. The design incorporates high-quality components and efficient heat dissipation to maintain optimal temperatures under normal and moderate loads. Efficient cooling is crucial for maintaining system stability, especially in the more compact mATX form factor.

Audio and Additional Features

Audio is handled by the Realtek ALC897 codec, providing an 8-channel (7.1) high-definition audio solution. While not explicitly detailed, the motherboard likely includes features such as MSI’s Click BIOS 5 for easy BIOS navigation and customization, and EZ Debug LEDs for troubleshooting. The pre-installed I/O shield simplifies installation.
