Model ROG STRIX B860-I GAMING WIFI

  • Ready for Intel Core Ultra Series 2 processors with LGA 1851 socket
  • Robust 10+1+2+1 power stages rated at 80A each for stable delivery
  • DDR5 memory support up to 9066 MT/s with AEMP III and XMP 3.0 profiles
  • Two M.2 slots including PCIe 5.0 x4 and PCIe 4.0 x4 for fast storage
  • Thunderbolt 4 USB Type-C plus 2.5G LAN and WiFi7 for high-speed connectivity

Ready for Intel Core Ultra Series 2

This Mini-ITX board uses the Intel B860 chipset and an LGA 1851 socket to support Intel Core Ultra processors (Series 2). It provides two 288-pin DDR5 slots running in dual-channel mode up to 96 GB. The compact form factor targets builders who want a small system with modern connectivity.

Robust power delivery under sustained load

A 10+1+2+1 phase design uses 80 A power stages alongside ProCool connectors, MicroFine alloy chokes and premium metallic capacitors. Massive heatsinks with an integrated I/O cover, high-conductivity thermal pads and an L-shaped heatpipe move heat away from the VRM during extended workloads. One M.2 slot sits under a large heatsink to keep PCIe 5.0 storage cool.

Straightforward Mini-ITX installation

The board fits standard Mini-ITX mounting points and uses a 24-pin ATX plus an 8-pin CPU power connector. The pre-mounted I/O shield simplifies rear-panel alignment. Only two DIMM slots are present, so memory population is limited to a pair of modules. The single PCIe 5.0 x16 SafeSlot leaves no room for a second expansion card.

Questions about this item

How much heat do the 80A power stages and L-shaped heatpipe handle during all-day loads?

The 10+1+2+1 phase design uses 80A stages with MicroFine alloy chokes and metallic capacitors, while massive heatsinks, high-conductivity pads and an L-shaped heatpipe spread heat across the I/O cover.

Which DDR5 kit and CPU cooler clearance do I need for this Mini-ITX board?

Two 288-pin DDR5 slots support up to 96GB at 9066 MT/s via XMP 3.0 or AEMP III; the compact layout fits standard low-profile coolers that clear the VRM heatsink.

Will my PCIe 4.0 SSD and SATA drives work in the two M.2 slots and four SATA ports?

The top M.2_1 slot runs PCIe 5.0 x4 for 2260/2280 drives, the second M.2_2 slot runs PCIe 4.0 x4 for 2242/2260/2280 drives, and four SATA 6Gb/s ports support RAID 0/1/5/10.
