ASRock B860M Pro RS WiFi

The B860M Pro RS WiFi is ASRock's budget micro-ATX entry for Intel's B860 chipset, giving Core Ultra Series 2 builders a PCIe 5.0 GPU slot and CUDIMM memory support in a compact form factor at an entry-level price.

Power delivery uses a 10+1+1+1+1 phase design with Dr.MOS stages covering VCore, GT, and SA rails, sufficient for Core Ultra 5 and Core Ultra 7 chips at stock clocks. Four DDR5 DIMM slots (CUDIMM-capable) support up to 256GB total, with a native speed of 5600MHz and overclocking rated up to 8666+ MT/s via XMP 3.0. Expansion includes a PCIe 5.0 x16 slot for the GPU and a PCIe 4.0 x4 slot. Storage covers one "Blazing M.2" PCIe 5.0 x4 slot and two "Hyper M.2" PCIe 4.0 x4 slots, plus four SATA3 connectors. A Realtek 2.5 Gigabit LAN controller handles wired networking, paired with an 802.11axe Wi-Fi 6E module offering dual-band 2x2 support. Audio uses a Realtek ALC897 codec with Nahimic enhancement. Against the Gigabyte Z890M FORCE DUO X WIFI7 in this catalog, the B860M Pro RS WiFi trades the Z890 chipset's extra overclocking features for B860's lower price, and Wi-Fi 6E instead of Wi-Fi 7, making it the budget alternative for micro-ATX Intel builds.
