This article covers ASUS intel Core Ultra Processors (Series 2) Socket LGA1851 対応 B860 搭載 ATX マザーボード.

Overview

The ASUS ROG STRIX B860-F GAMING WIFI is an ATX motherboard built around the Intel B860 chipset, designed exclusively for Intel Core Ultra processors (Series 2) on the LGA1851 socket. It supports DDR5 memory up to 192GB with overclocking speeds reaching 9066MT/s, making it a solid choice for both gaming and productivity builds.
This board carries the ROG STRIX DNA with a robust 16+1+2+1 power stage design (80A each), ProCool II connectors, and an 8-layer PCB for stable power delivery under load. ASUS also integrates AI-driven features like AI Cooling II and AI Networking II to automatically optimize system performance and thermals.
Positioned in the mid-high tier, the B860-F offers a compelling balance of modern connectivity—PCIe 5.0, Thunderbolt 4, Wi-Fi 7—and reasonable pricing compared to flagship Z890 boards. It's ideal for users who want the latest platform without paying a premium for extreme overclocking or extra PCIe lanes.

Compatibility Guide

CPU socket is LGA1851, compatible only with Intel Core Ultra processors (Series 2, e.g., Core Ultra 5 225H, Core Ultra 7 265K, Core Ultra 9 285K). No backward compatibility with LGA1700 or earlier sockets.
Memory: 4x DDR5 DIMM slots, dual-channel, max 192GB. Supports XMP 3.0 and ASUS AEMP III for memory overclocking. Speeds up to 9066MT/s (OC) depending on CPU and memory kit.
Form factor: ATX (305mm x 244mm). Fits standard ATX cases. Expansion: 1x PCIe 5.0 x16 slot (from CPU), additional PCIe 4.0/3.0 slots from chipset. Storage: 4x M.2 slots (1x Gen5, 3x Gen4), 4x SATA 6Gbps ports.
Power: 24-pin main connector, 8-pin + 4-pin CPU power (or 8+8 depending on PSU). Recommended PSU wattage: 650W for mid-range builds, 750W+ for high-end GPU configurations.

Product Info

Released in early 2025 alongside the B860 chipset lineup. Pricing in Japan is around ¥37,500 (online retailers). Warranty: 3 years via ASUS Japan authorized distributors, including pin damage coverage.
Market positioning: mid-high tier. It lacks the extra PCIe lanes and full overclocking freedom of Z890, but delivers excellent real-world performance for Core Ultra CPUs. The inclusion of Thunderbolt 4, Wi-Fi 7, and PCIe 5.0 makes it future-proof for most users.

Best Use Cases

  • Gamers: Pair with a PCIe 5.0 GPU for high-refresh gaming. Wi-Fi 7 ensures low-latency online play. Not for extreme overclockers—Z890 offers more headroom.
  • Content Creators: Thunderbolt 4 for fast external storage, multiple M.2 slots for RAID configurations. DDR5-9066 support provides ample bandwidth for video editing and 3D rendering.
  • Energy-conscious builders: Core Ultra's efficiency combined with B860's lower power draw makes for a cool, quiet system. The VRM is overkill for stock operation, but that's fine.
  • Budget platform adopters: Get the latest CPU socket and DDR5 without paying Z890 prices. Ideal for a secondary PC or a cost-effective primary build.

Things to Consider

The most critical limitation is socket exclusivity—only Core Ultra (Series 2) CPUs work. If you already own a 13th/14th Gen Core CPU, this board is not compatible.
B860 chipset offers fewer PCIe lanes than Z890. If you plan to run multiple PCIe 5.0 devices (e.g., GPU + SSD), the second device will be limited to chipset bandwidth. For single GPU + single Gen5 SSD, it's fine.
Memory overclocking to 9066MT/s is not guaranteed; stability depends on CPU IMC and memory kit quality. Always check the QVL before buying high-speed RAM.

FAQ

Q: Can I use an Intel Core i7-14700K with this motherboard?
A: No. The LGA1851 socket is only for Core Ultra (Series 2) processors. 14th Gen Core uses LGA1700 and is physically incompatible.
Q: How many PCIe 5.0 M.2 slots does it have?
A: Only one M.2 slot supports PCIe 5.0 x4. The other three are PCIe 4.0 x4. For multiple Gen5 SSDs, consider a Z890 board.
Q: Does the board include Bluetooth?
A: Yes, Bluetooth 5.4 is integrated with the Wi-Fi 7 module. It supports the latest peripherals and audio devices.
