Written analysis

ASUS ROG STRIX B860-I GAMING WIFI at a glance

The ASUS ROG STRIX B860-I GAMING WIFI uses the Mini-ITX form factor, LGA 1851 socket, and B860-I chipset. This is a balanced mainstream platform: enough expansion and connectivity for a performance PC without paying only for flagship extras.

Memory support is DDR5 across 2 DIMM slots, with up to 128 GB and rated overclocked speeds up to 9066 MT/s. XMP / EXPO memory-profile support is recorded for easier tuning.

Best fit: a performance gaming and productivity PC that needs a balanced board without workstation-class excess.

Power delivery

The calculated VRM score is 41.0, placing the power delivery in the mid-range class. The board lists 10 CPU power phases, 80 A power stages in a 10(80A)+1(80A)+2(80A)+1(80A) layout. CPU power input is listed as 1. It is a sensible match for mainstream processors, with conservative tuning on higher-power chips.

Expansion and storage

The expansion and storage score is 56.0: balanced . The platform supports PCIe 5.0. Physical expansion includes 1 ×16 slot.

On-board storage consists of 2 M.2 slots and 4 SATA ports. Supported M.2 lengths are listed as 2242, 2260, 2280. The two-slot layout covers a typical OS-and-games or OS-and-project-drive setup.

Connectivity and rear I/O

The connectivity score is 68.0, rated adequate . Wireless networking is Wi-Fi 7 ; wired networking is 1 x Intel® 2.5Gb Ethernet at up to 2500 Mbps. Bluetooth 5.4 is included. The recorded USB provision is 8 rear connections and 1 front-panel connections. USB4 Type-C is available at the rear. The specification sheet below separates every USB speed and connector type.

Display connectivity includes HDMI 2.1, DisplayPort 1.4, USB-C DisplayPort. These motherboard outputs require a processor with integrated graphics.

Audio

The audio score is 81.0. This is a high-end onboard implementation using Realtek ALC1220P, suitable for good headsets, powered speakers, and everyday content work. The rear panel has 2 analogue jacks. Optical S/PDIF is present for digital audio equipment.

Buying verdict

Overall quality is 64.60, a mainstream result. The essential platform features are covered, while premium I/O and tuning extras are more selective.

At the recorded Amazon price, the quality-to-price score is 51.3—a balanced value for its feature class.
