ASUS ROG Strix B860-A Gaming WiFi

A B860 ATX board with ROG Strix DNA — PCIe 5.0, four M.2 slots, USB4, Wi-Fi 7 and ROG SupremeFX audio forIntel Core Ultra Series 2 builds without the Z890 price tag.
PCIe 5.0 x164x M.2 (1x Gen5)USB4 20GBpsWi-Fi 7 + 2.5GBE

The ASUS ROG Strix B860-A Gaming WiFi is a full-size ATX motherboard forIntel Core Ultra (Series 2) processors on the LGA1851 socket. Built on the Intel B860 chipset with a 14+1+2+1 power stage design, ProCool connectors and MicroFine alloy chokes, it pairs four DDR5 DIMM slots (up to 256GB at 9066+ MT/s O.C. with CUDIMM support) with a reinforced PCIe 5.0 x16 SafeSlot, four M.2 slots — including one PCIe 5.0 x4 wired to the CPU — and four SATA 6GB/s ports. Connectivity covers Realtek 2.5GBE Ethernet, 2x2 Wi-Fi 7 (802.11be) with Bluetooth 5.4, and a USB4 (20GBps) Type-C port for fast peripherals. ROG Strix styling adds Aura Sync RGB, ROG SupremeFX premium audio with Dolby Atmos and ASUS' suite of memory tuning features.

Compatibility Note: LGA1851 socket only — supportsIntel Core Ultra Series 2 processors. Older 12th/13th/14th Gen LGA1700 CPUs are not compatible. DDR5 memory only — DDR4 cannot be used. The B860 chipset does not support full CPU overclocking (memory and NPU OC are still possible) — choose Z890 if you need CPU multiplier overclocking. M.2_4 shares bandwidth with the secondary PCIe x16 slot.
Best For
✓Intel Core Ultra Series 2 gaming builds without CPU overclocking
✓ Builders who want ROG Strix styling at a B860 price
✓ DDR5 enthusiasts using CUDIMM kits
✓ Creators using a USB4 Type-C display / dock

Key Features

 
14+1+2+1 Power Stages
A digital VRM with 14-phase VCORE design, ProCool connectors, MicroFine alloy chokes and premium metallic capacitors keeps even theIntel Core Ultra 9 285K stable at stock — though the B860 chipset itself doesn't permit full CPU multiplier overclocking.
 
PCIe 5.0 + 4x M.2 Storage
A reinforced PCIe 5.0 x16 SafeSlot for next-gen GPUs, plus four M.2 slots — one PCIe 5.0 x4 from the CPU and three PCIe 4.0 x4 from the chipset, with M.2 Q-Latch and M.2 Q-Slide tooling for screwless installation.
 
DDR5 9066+ MT/s + AEMP III
Four DDR5 DIMM slots support up to 256GB with overclocking up to 9066+ MT/s and CUDIMM support. ASUS-exclusive AEMP III, DIMM Fit Pro and a built-in clock Generator isolate CPU base clock from memory for tighter overclocking.
 
USB4 + Wi-Fi 7 + ROG SupremeFX
A USB4 (20GBps) Type-C port for fast data and display, 2x2 Wi-Fi 7 with Bluetooth 5.4, ROG SupremeFX ALC1220P codec with Savitech SV3H712 amp and Dolby Atmos, plus Aura Sync RGB lighting with Addressable Gen 2 RGB headers.

Frequently Asked Questions

Which CPUs are supported?
Intel Core Ultra Series 2 processors on the LGA1851 socket — including the Core Ultra 9 285K. Older LGA1700 CPUs are not compatible. Always check ASUS' official CPU support list and required BIOS version.
Can I overclock my CPU on this board?
No — the Intel B860 chipset does not support full CPU multiplier overclocking. Memory overclocking up to 9066+ MT/s and NPU tuning are still possible. If you need full CPU overclocking, choose a Z890 board instead.
What's the difference between B860-A and B860-F?
Both are ROG Strix B860 ATX boards with similar core specs. The main differences: the B860-A uses 14+1+2+1 power stages and a USB4 (20GBps) Type-C port, while the B860-F uses 12+1+2+1 power stages and a Thunderbolt 4 / USB4 (40GBps) Type-C port. The B860-F is the higher-tier of the two.
Does the M.2_4 slot affect the secondary PCIe x16 slot?
Yes — M.2_4 shares bandwidth with the secondary PCIe x16 slot (PCIEX16 G4). When that PCIe slot is operating, M.2_4 is disabled. Plan your storage and expansion card layout accordingly.
Singular Expert Insight
Choose the B860-A if you want ROG Strix premium audio, RGB and memory tuning on a B860 board for a non-overclockedIntel Core Ultra Series 2 build at a more accessible price point. If you want a stronger VRM or a Thunderbolt 4 (40GBps) port, step up to the ROG Strix B860-F. If you plan to overclock your CPU, you need a Z890 board such as the ROG Strix Z890-F.
