ASUS ROG STRIX B850-I Gaming WIFI DDR5 AMD Motherboard

The ASUS ROG STRIX B850-I Gaming WIFI is a feature-packed Mini-ITX motherboard engineered for AMD Ryzen 9000, 8000, and 7000 series desktop processors on the AM5 platform. Despite its compact 6.7 x 6.7 inch (17 cm x 17 cm) footprint, it refuses to compromise on performance or connectivity — making it a strong choice for small-form-factor gaming and high-performance workstation builds alike. At the heart of its performance story is end-to-end PCIe 5.0 support. With Ryzen 9000 and 7000 series CPUs, the single x16 expansion slot runs at PCIe 5.0 speeds, while both M.2 slots (M.2_1 and M.2_2, supporting 2242/2260/2280 form factors) also operate at PCIe 5.0 x4 — enabling the fastest NVMe storage available today. Note that Ryzen 8000 series processors operate the x16 slot and M.2 slots at PCIe 4.0 speeds. Memory support is equally forward-looking: two DDR5 DIMM slots accommodate up to 128 GB of unbuffered DDR5 memory in a dual-channel configuration, with overclocked speeds reaching 8400+ MT/s via AMD EXPO and ASUS AEMP profiles. Connectivity is a highlight of this board. The integrated Wi-Fi 7 (802.11be) module supports 2×2 antennas across 2.4 GHz, 5 GHz, and 6 GHz bands with up to 2.9 Gbps transfer rate at 160 MHz bandwidth, complemented by Bluetooth 5.4. Wired networking is handled by a dedicated Intel 2.5Gb Ethernet port with ASUS LANGuard protection. The rear I/O provides eight USB ports — one USB 20 Gbps Type-C, five USB 10 Gbps (four Type-A plus one Type-C with DisplayPort Alt Mode), and two USB 2.0 Type-A — plus five additional front-panel USB headers. Audio is handled by the ROG SupremeFX system featuring a Realtek ALC4080 codec, delivering 120 dB SNR stereo playback and 110 dB SNR recording input, a Savitech SV3H712 amplifier, rear optical S/PDIF output, and support for up to 32-bit/384 kHz playback on the front panel. Dolby Atmos software support is included. For builders, ASUS Q-Design features — including M.2 Q-Latch, M.2 Q-Slide, PCIe Q-Release Slim with SafeSlot, Q-DIMM, and BIOS FlashBack — simplify assembly and maintenance. Two Addressable Gen 2 headers support Aura Sync RGB ecosystems. The board ships with a 3-year warranty.
