MSI Pro B860M-A Wifi DDR5 Intel Motherboard

The MSI Pro B860M-A WiFi DDR5 is a Micro-ATX motherboard built on the Intel B860 chipset, designed for Intel Core Ultra Series 2 processors in the LGA 1851 socket. It brings together a strong connectivity lineup, next-generation wireless networking, and a capable storage platform in a compact form factor suited to both system integrators and enthusiast builders. At the heart of its wireless capability is the Intel Killer BE1750x module, delivering Wi-Fi 7 (802.11be) with tri-band support across 2.4 GHz, 5 GHz, and 6 GHz frequencies up to 5.8 Gbps, alongside MU-MIMO, MLO, and 4KQAM. Bluetooth 5.4 is also supported. Wired networking is handled by the Intel Killer E5000 controller, offering 5 Gbps LAN for users who need high-bandwidth wired connectivity. Memory support spans four DDR5 UDIMM slots with a maximum capacity of 256 GB. Speeds range from 4800 to 6400 MT/s under JEDEC specification, and up to 8600 MT/s in overclocked configurations with XMP 3.0 profiles. CUDIMM support is included. The primary PCIe slot (PCI_E1) runs at PCIe 5.0 x16 from the CPU, while remaining slots operate at PCIe 4.0 from the chipset. Storage is well-served by three M.2 slots: M.2_1 reaches PCIe 5.0 x4 (CPU-direct), M.2_2 supports PCIe 4.0 x4, and M.2_3 supports PCIe 4.0 x2. Four SATA 6 Gb/s ports are also available, with RAID 0, 1, 5, and 10 support for SATA arrays. The rear I/O includes a Thunderbolt 4 port capable of 40 Gbps data transfer and DisplayPort 2.1 output at up to 4K@120Hz or 8K@60Hz via USB Type-C. Additional display outputs include HDMI 2.1 (4K@60Hz) and DisplayPort 1.4 (4K@60Hz), available when using a processor with integrated graphics. USB connectivity is extensive: rear ports include 2x USB 2.0, 2x USB 5 Gbps Type-A, 1x USB 5 Gbps Type-C, 1x USB 10 Gbps Type-A, and 1x Thunderbolt 4 Type-C. Front panel headers add 4x USB 2.0, 4x USB 5 Gbps Type-A, and 1x USB 10 Gbps Type-C. Audio is provided by a Realtek ALC897 codec delivering 7.1-channel high-definition output. Onboard RGB features include two ARGB V2 headers, one RGB header, and four EZ Debug LEDs.
