Combo contents

This bundle pairs an ASUS PRIME B860M-K motherboard with an Intel Core Ultra 7 265K processor and Shin-Etsu X-23-7868-2D thermal grease. The board uses the LGA 1851 socket and Intel B860 chipset in a micro-ATX layout. A 6+1+1+1 phase digital power design with ProCool 8-pin connector feeds the CPU. DDR5 memory is supported with AEMP III optimisation for speeds of 7600 MT/s and above.

Suitability

Builders who want a ready-matched CPU and motherboard with quality paste included will find this combo convenient. The 125 W processor delivers 30 MB L3 cache and 36 MB L2 cache alongside integrated Intel Graphics. Users needing a bundled cooler or a larger ATX form factor should look at other options. The board provides one PCIe 5.0 x4 M.2 slot and one PCIe 4.0 x4 M.2 slot for fast storage.

Included extras

Shin-Etsu X-23-7868-2D grease ships in the box with a thermal conductivity of 6.2 W/m·K and resistance of 0.07 °C·cm²/W. Its grey paste has a viscosity of 100 Pa·s and is rated as easy to apply. The manufacturer suggests a replacement cycle of two years against an official lifespan of three to five years. The motherboard adds 2.5 Gb Ethernet, front USB 5 Gbps Type-C header, rear USB 10 Gbps Type-A port, dual addressable Gen2 RGB headers with Aura Sync, Fan Xpert 2+ controls and Digi+ VRM power management.
