Combo Contents

This bundle pairs an ASUS TUF GAMING B860-PLUS WIFI motherboard with an Intel Ultra 5 245K processor and Shin-Etsu X-23-7868-2D thermal grease. The board uses the Intel B860 chipset and LGA 1851 socket, built for Intel Core Ultra Series 2 CPUs. It targets builders who want a ready-to-install platform for gaming and AI workloads.

DDR5 Memory Limits

Four 288-pin slots support dual-channel DDR5 up to 192 GB total capacity. Rated speeds reach 8666 MT/s when overclocked, with XMP and AEMP III profiles available. The board also provides one PCIe 5.0 x16 slot from the CPU and one PCIe 4.0 x16 slot from the chipset that shares bandwidth with a PCIe 4.0 x1 slot.

Deciding Specification

The CPU delivers 24 MB L3 cache and 26 MB L2 cache on a 3 nm process with a 125 W base power rating. Networking includes Wi-Fi 7 (802.11be), Bluetooth 5.4 and 2.5 Gbps Ethernet. Storage options comprise one PCIe 5.0 M.2 slot plus two PCIe 4.0 M.2 slots, all heatsinked, alongside four SATA 6 Gb/s ports.

Questions about this item

Should I pick the DDR5 8666 MT/s memory or a slower kit for this TUF GAMING B860-PLUS WIFI combo?

The board supports up to 8666+ MT/s when overclocked with XMP or AEMP III profiles, so a high-speed DDR5 kit will run at its rated frequency if the memory controller on the Ultra 5 245K can sustain it; a slower kit will work fine but leaves headroom unused.

What does the 125 W base power of the Ultra 5 245K mean for my cooler choice?

The processor has a 125 W base power rating and no cooler in the box, so you need a CPU cooler rated for at least that TDP — preferably higher — to keep temperatures in check under sustained loads.

Which M.2 slot gives me PCIe 5.0 x4 speeds and what size drives fit?

The M.2_1 slot is wired to the CPU and runs at PCIe 5.0 x4, accepting 2280 drives; the other two slots run at PCIe 4.0 x4 and take 2280, 22110, 2242 or 2260 lengths.
