Combo contents

This bundle pairs the ROG STRIX B860-I GAMING WIFI motherboard with an Intel Core Ultra 7 265K processor and Shin-Etsu X-23-7868-2D thermal grease. The board uses the Intel B860 chipset on a Mini-ITX PCB with an LGA 1851 socket. It is aimed at builders who want a compact platform ready for advanced AI workloads and high-speed connectivity.

Before ordering

Verify that your chassis accepts a Mini-ITX motherboard and that the CPU cooler you plan to use clears the board’s integrated I/O cover and L-shaped heatpipe. The processor draws 125 W, so ensure your power supply has the required 8-pin ProCool connector and sufficient headroom. You will need DDR5 modules; the board has two 288-pin slots supporting up to 96 GB in dual-channel mode.

Under sustained load

The 10+1+2+1 power-stage design uses 80 A stages with MicroFine alloy chokes and metallic capacitors to deliver stable current during extended compute tasks. Massive heatsinks linked by the L-shaped heatpipe spread heat from the VRM and the primary M.2 slot. WiFi7 and 2.5 Gbps LAN maintain throughput, while the Realtek ALC1220P codec drives 7.1 audio without thermal throttling.

Questions about this item

Does the combo ship with thermal grease, or do I need to buy paste separately?

The package includes Shin-Etsu X-23-7868-2D thermal grease, so no separate purchase is required.

Which DDR5 speed should I target for the Ultra 7 265K on this board?

The motherboard supports up to 9066+ MT/s when overclocked; pick a kit rated at or above your desired frequency with XMP or AEMP III support.

What does the 125 W rating mean for daily cooling on this mini-ITX build?

The processor has a 125 W base power; pair it with a capable low-profile or AIO cooler that fits the LGA 1851 socket and the compact chassis.
