The ASUS ROG STRIX B860-I GAMING WIFI is a Mini-ITX motherboard for Intel Core Ultra Series 2 processors, suited to compact gaming PCs that need DDR5 memory, a PCIe 5.0 x16 graphics slot, and Wi-Fi 7 connectivity.
Recommended For
- Builders planning a compact Mini-ITX gaming PC around an Intel Core Ultra Series 2 processor who want a full-size graphics card and onboard Wi-Fi 7 without moving to a larger motherboard. Reviews have tested it in small-form-factor builds and found its power delivery suitable for high-end CPUs.
- Small-form-factor PC builders who need fast connections for external storage, docks, or displays: the board combines Thunderbolt 4, another 20Gbps USB-C port, Wi-Fi 7, and 2.5Gb Ethernet in a Mini-ITX layout.
- DIY enthusiasts building a compact Intel system who want to tune DDR5 memory and use PCIe 5.0 storage. A hands-on review tested high memory speeds on this board, while noting that CPU overclocking is not the B860 chipset’s focus.
- Users assembling a compact workstation or gaming PC who want a single graphics card plus up to two onboard M.2 drives and four SATA drives, without needing multiple expansion-card slots.
