MSI PRO B860-P
MSI PRO B860-P
The MSI PRO B860-P motherboard, with its Intel B860 chipset and Intel 1851 socket, is a professional ATX-format solution that supports modern Intel Core Ultra processors and four slots for DDR5 memory with speeds of up to 8800+ MT/s. The board is designed for simple installation, high performance, and reliability, offering advanced features like PCIe 5.0, Thunderbolt 4, 5G LAN, and a powerful 12+1+1+1 DRPS power system with 8+4-pin processor connectors. The Frozr Design cooling system combines an extended passive heatsink with a massive VRM heatsink covering the top MOSFETs, which uses high-quality thermal pads with a thermal conductivity of 7W/mK and additional cooling pads for the chokes.

Easy installation and advanced EZ DIY features
Installation and maintenance are simplified with EZ DIY solutions. The EZ PCIe Clip II mechanism enables easy removal of the graphics card with a single finger using a spring-loaded mechanism, which is especially useful in tight cases. Colour-coded connectors for pumps, fans, and ARGB components make it easy to navigate the cabling. The pre-installed I/O shield eliminates the need for manual fitting and ensures correct alignment. The EZ Antenna connects without any twisting, simply by pushing it on. Quick diagnostics are facilitated by the EZ Debug LED and EZ Memory Detection LED, which instantly identify the source of any problems.
Powerful power system and overclocking support
The 12+1+1+1 DRPS power system, with twelve Vcore phases and separate phases for SA, GT, and VNNAON, ensures a stable power supply even for more demanding processors. The board uses a six-layer, server-grade PCB material, optimised for higher bandwidth and faster data transfer. Solid pins on the 8-pin and 24-pin connectors ensure a stable power transfer under heavy loads. Overvoltage protection is provided by Transient Voltage Suppressors (TVS), and overcurrent protection shields the USB ports, DDR memory slots, PWM circuits, and the processor. Overclocking is simplified with the MSI Click BIOS X function, which supports XMP profiles for automatic overclocking of compatible DDR memory. Memory Extension Mode provides optimised parameters for lower latency and higher performance at the same frequency.

Choosing a motherboard
When choosing a motherboard (or mainboard), it's important to pay close attention to the socket type, form factor, and chipset. These are the most crucial parameters, as they ensure the board is compatible with the processor, expansion cards, and other components. The specific socket determines which processor you can choose, while the other connectors will dictate the selection of other components for your future PC.Specifications
