Combo for Intel Core Ultra Series 2

This combo pairs the ASUS PRIME 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 ready-to-run platform for AI workloads and high-performance computing without selecting parts separately.

Sustained-load behaviour

The 8+1+1+1 80A DrMOS power stages and enlarged VRM heatsinks are designed to deliver stable power during extended heavy workloads. A dedicated M.2 heatsink covers the PCIe 5.0 slot while a PCH heatsink handles chipset heat. Hybrid fan headers and Fan Xpert 2+ allow custom fan curves so temperatures stay controlled over long sessions.

Installation and common issues

Pre-mounted I/O shield, Q-DIMM latches, Q-LED indicators and Q-Dashboard simplify the build process. The LGA 1851 socket requires careful CPU alignment to avoid bent pins. Applying the included Shin-Etsu grease evenly is critical because the processor runs at 125W and has no stock cooler. Builders must supply their own cooling solution.

Questions about this item

Will the included thermal grease cover the CPU cooler installation?

The bundle includes Shin-Etsu X-23-7868-2D thermal grease, which is sufficient for applying between the Intel Ultra 7 265K and your chosen cooler.

What DDR5 memory speeds can I run with this motherboard and CPU combination?

The board supports DDR5 up to 8200+ MT/s when overclocked via XMP or ASUS Enhanced Memory Profile II, running in dual-channel across four slots.

Which M.2 slot should I use for the fastest possible SSD performance?

Use the M.2_1 slot connected to the CPU; it supports PCIe 5.0 x4 mode for 2242, 2260 and 2280 drives and includes a dedicated heatsink.
