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.
