ASUS ROG Strix B850-I Gaming WiFi

The ROG Strix B850-I Gaming WiFi updates ASUS's mainstream AM5 ITX board to the B850 chipset, keeping PCIe 5.0 on the GPU slot and primary M.2 while adding AI Cache Boost tuning aimed at Ryzen X3D chips in small-form-factor builds.

A 10+2+1 power stage design with 90A-rated stages for both VCore and SoC gives this board solid headroom for current Ryzen 9000 chips, including X3D variants, without moving up to a pricier X870E board. Two DDR5 DIMM slots support up to 128GB total capacity, with AMD EXPO enabling speeds of up to 8200+ MT/s on Ryzen 9000 (9600+ MT/s on Ryzen 8000). The board includes one PCIe 5.0 x16 slot and two PCIe 5.0 x4 M.2 slots in the 2242-2280 form factor range, giving flexibility for both full-length and compact SSDs. A 2.5GbE Intel LAN controller pairs with Wi-Fi 7 for wireless connectivity. Audio runs through a Realtek ALC4080 codec with a Savitech SV3H712 amplifier, and Q-Latch tool-free M.2 installation carries over from the B650E-I. Compared to the ROG Strix B650E-I Gaming WiFi in this catalog, the B850-I gains AI Cache Boost tuning and Wi-Fi 7 while keeping a similar power delivery tier, making it the more current pick for new Ryzen 9000 ITX builds.
