Combines an Intel Core Ultra 7 265K processor with a B860 ATX motherboard featuring DDR5 support up to 8666 MT/s, three M.2 slots, Wi-Fi 7, 2.5 Gbps LAN, and 12+2+1 80A DrMOS power stages
Model TUF GAMING B860-PLUS WIFI
CPU +Ultra 7 265K
This combo pairs the ASUS TUF GAMING B860-PLUS WIFI motherboard with the Intel Core Ultra 7 265K processor and Shin-Etsu X-23-7868-2D thermal grease. The board uses the Intel B860 chipset on an ATX form factor with an LGA 1851 socket. It targets builders who want a platform prepared for demanding AI workloads and high-performance computing. The processor operates at a 125W base power with 30MB L3 and 36MB L2 cache.
The included Shin-Etsu X-23-7868-2D compound ensures effective heat transfer between the CPU and your chosen cooler. Motherboard conveniences such as PCIe Slot Q-Release, M.2 Q-Latch, Q-Antenna, Q-Dashboard, Q-LED and BIOS FlashBack simplify assembly and troubleshooting. A pre-mounted I/O shield saves an installation step. These additions reduce build friction without changing the core specifications of the board or processor.
The platform delivers one PCIe 5.0 x16 slot from the CPU and a second PCIe 4.0 x16 slot from the chipset that runs at x4 mode, sharing bandwidth with the PCIe 4.0 x1 slot. Storage options include one PCIe 5.0 M.2 slot and two PCIe 4.0 M.2 slots, all with heatsinks. Networking tops out at 2.5Gbps Ethernet and Wi-Fi 7 (802.11be) with Bluetooth 5.4. Rear USB reaches 20Gbps Type-C with DP Alt mode while front-panel USB offers 10Gbps Type-C.

Other versions of this model
The bundle includes Shin-Etsu X-23-7868-2D thermal grease, supplied specifically for the included processor.
The motherboard supports ASUS Enhanced Memory Profile III (AEMP III) which automatically optimises compatible DDR5 modules beyond base JEDEC speeds.
The top M.2_1 slot runs at PCIe 5.0 x4 directly from the CPU, while M.2_2 and M.2_3 run from the chipset, leaving the PCIe 5.0 x16 graphics slot unaffected.
