+CPU +Ultra 5 245K

  • Ready for Intel Core Ultra Series 2 processors with LGA 1851 socket
  • 12+2+1 80A DrMOS power stages for stable CPU delivery
  • DDR5 memory support up to 8800 MT/s and 192 GB capacity
  • One PCIe 5.0 M.2 slot plus two PCIe 4.0 M.2 slots with heatsinks
  • Onboard Wi-Fi 7 and 2.5 Gb Ethernet for high-speed networking

Combo purpose

This package pairs the ASUS TUF GAMING B860M-PLUS WIFI motherboard with an Intel Ultra 5 245K processor and Shin-Etsu X-23-7868-2D thermal grease. It targets builders who want a ready-to-assemble foundation for an AI-capable desktop without selecting components separately. The board uses the Intel B860 chipset and LGA 1851 socket to support Core Ultra Series 2 CPUs. The 125W processor brings 24MB L3 and 26MB L2 cache plus integrated Intel Graphics.

Interface limits

Memory runs on four 288-pin DDR5 slots in dual-channel mode up to 192GB with XMP and AEMP III profiles. Expansion includes one PCIe 5.0 x16 slot from the CPU and one PCIe 4.0 x4 slot from the chipset. Storage offers three M.2 Key-M slots: one 2280 at PCIe 5.0 x4, one 2242/2260/2280 at PCIe 4.0 x4, and one 2280 at PCIe 4.0 x4, plus four SATA 6Gb/s ports with RAID 0/1/5/10. Rear I/O supplies USB 20Gbps Type-C with DP Alt mode, two USB 10Gbps Type-A, four USB 5Gbps Type-A, one USB 2.0 Type-A, HDMI, DisplayPort, 2.5Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4.

Deciding spec

The power delivery uses 12+2+1 80A DrMOS stages fed by 8+8 pin ProCool connectors, alloy chokes and durable capacitors. This VRM design determines whether the board can sustain the Ultra 5 245K at its rated power without throttling.

Highlights

  • Ready for Intel Core Ultra Series 2 processors with LGA 1851 socket
  • 12+2+1 80A DrMOS power stages for stable CPU delivery
  • DDR5 memory support up to 8800 MT/s and 192 GB capacity
  • One PCIe 5.0 M.2 slot plus two PCIe 4.0 M.2 slots with heatsinks
  • Onboard Wi-Fi 7 and 2.5 Gb Ethernet for high-speed networking

Questions about this item

Should I pick the combo with the Ultra 5 245K or look for a board-only option?

This listing is a fixed bundle that includes the TUF GAMING B860M-PLUS WIFI motherboard, the Intel Ultra 5 245K processor and a tube of Shin-Etsu X-23-7868-2D thermal grease; no board-only variant is offered here.

What does the 12+1+2+1 80A power-stage design actually deliver for the Ultra 5 245K?

The 12+1+2+1 DrMOS stages rated at 80 A each feed the processor's 125 W base power through dual 8-pin ProCool connectors, giving stable voltage for sustained boost clocks and overclocking headroom.

Which M.2 slot runs at PCIe 5.0 and what speed does that cap at?

The primary M.2_1 slot is wired to the CPU and operates at PCIe 5.0 x4, while the two chipset-linked slots run at PCIe 4.0 x4; all three accept 2280 drives and include heatsinks.
