MSI B860M Gaming Plus WiFi mATX Motherboard With LGA 1851

BRAND-NEW SEALED ~ 1 YEAR WARRANTY EXPERT FEATURES Intel Core Ultra Series 2 Platform : The Intel B860 chipset and LGA 1851 socket create a properly matched foundation for compatible Intel Core Ultra desktop processors from Series 2. Massive DDR5 Headroom : Four DDR5 UDIMM slots support up to 256GB, Intel XMP 3.0, CUDIMM, dual-channel operation, and memory speeds reaching 8800+ MT/s when overclocked with compatible hardware. 12+1+1+1 Power Architecture : MSI’s Duet Rail power system, P-PAK design, Core Boost, 8+4-pin CPU power input, and six-layer server-grade PCB are built to keep demanding gaming loads properly fed. PCIe 5.0 Graphics Slot : The primary CPU-connected PCIe slot supports PCIe 5.0 x16 and Steel Armor reinforcement, giving compatible modern graphics cards a full-speed, physically strengthened connection. Four Full-Length Expansion Slots : Beyond the primary x16 slot, the board provides two PCIe 4.0 x1 links and one PCIe 4.0 x4 link for compatible capture cards, sound cards, storage controllers, and networking upgrades. Triple M.2 Storage Arsenal : Install one PCIe 5.0 x4 SSD, one PCIe 4.0 x4 SSD, and one PCIe 4.0 x2 SSD, backed by four SATA 6Gb/s ports and SATA RAID support. Thunderbolt 4 Connectivity : The rear USB-C Thunderbolt 4 port supports up to 40Gbps transfers, USB4 devices, 15W charging, daisy-chaining, and display output reaching 8K with compatible processor graphics. Full-Speed Wi-Fi 7 : Intel Killer BE1750x wireless supports 2.4GHz, 5GHz, and regulation-dependent 6GHz operation, 320MHz channels, MLO, 4KQAM, and speeds reaching 5.8Gbps under suitable conditions. Bluetooth 5.4 Support : Connect compatible wireless headsets, controllers, keyboards, mice, and accessories, subject to chipset-vendor updates and the Windows 11 Bluetooth 5.4 support schedule. Intel Killer 5G LAN : The E5000 controller delivers wired networking up to 5Gbps for faster NAS transfers, game downloads, local servers, and high-speed internet connections. Serious USB Expansion : The board combines rear USB 10Gbps Type-A, rear USB 5Gbps Type-C and Type-A, front USB 10Gbps Type-C, front USB 5Gbps, and USB 2.0 connectivity. Flexible Integrated-Graphics Outputs : HDMI 2.1 and DisplayPort 1.4 support up to 4K at 60Hz, while Thunderbolt 4 supports DisplayPort 2.1 UHBR20 at up to 4K 120Hz or 8K 60Hz with a compatible CPU featuring integrated graphics. Frozr Thermal Design : An extended heatsink, heavy-plated VRM heatsink, M.2 Shield Frozr, chipset heatsink, 7W/mK MOSFET pads, and additional choke pads help control heat during sustained workloads. Liquid-Cooling Friendly Headers : One CPU-fan header, one pump/system combo header, and three system-fan headers provide broad cooling compatibility, including PWM/DC fans and pumps. EZ DIY Hardware : A pre-installed I/O shield, EZ PCIe Clip II, EZ M.2 Clip II, EZ M.2 Shield Frozr II, EZ Antenna, and EZ Debug LEDs take unnecessary pain out of assembly and troubleshooting. Clear CMOS Recovery : The rear Clear CMOS button resets BIOS settings when unstable tuning prevents a normal startup; the official specification page does not list a Flash BIOS button. 7.1-Channel Audio : The Realtek ALC897 codec supports 7.1-channel high-definition audio, while MSI Audio Boost adds isolated circuitry, dedicated capacitors, quality jacks, and de-pop protection.
