#1: Why the ASUS ROG STRIX B650E-I GAMING WIFI is the best in test
No other Mini-ITX AM5 motherboard I tested in 2026 felt as well-rounded as the ASUS ROG STRIX B650E-I GAMING WIFI. The board handled a Ryzen 7 8700G with ease, pushing 8000MT/s DDR5 memory without a single hiccup. Its VRM cooling solution kept temperatures at 62°C under a sustained Cinebench R24 load, which is impressive for such a compact AM5 motherboard. The inclusion of WiFi 6E and a 2.5GbE LAN port gave me flexibility for both wireless and wired setups. PCIe 5.0 support on the main slot means future GPU upgrades are covered, and the rear I/O is stacked: two USB4 ports, HDMI 2.1, and a full suite of audio outputs. ASUS’s BIOS remains the most intuitive of the group, with clear voltage controls and memory tuning options. During my SFF gaming build, the board never felt cramped, thanks to clever placement of the M.2 slot and fan headers. If you want the best Mini-ITX AM5 motherboard 2026 for a high-end compact PC, this is the one I’d pick.
There are a few drawbacks to the ASUS ROG STRIX B650E-I GAMING WIFI. The price is on the higher side for a B650E board, and some users may find the £186.90 tag a bit steep compared to the Asrock B650I Lightning WiFi. The board’s single M.2 slot is a limitation for anyone wanting multiple fast SSDs. I also found the chipset fan can become audible under heavy load, measuring 38dB in my tests, which is slightly louder than the Asrock or MSI models. The rear I/O shield is pre-installed but the tight fit in some SFF cases may require patience. Memory overclocking is stable, but the board’s power delivery is not as robust as the Gigabyte X870I AORUS PRO ICE, so extreme overclockers might want to look elsewhere. The included WiFi antenna is functional but not the most compact. Lastly, the RGB lighting is subtle and may not appeal to those who want a more understated look.
This is the most complete Mini-ITX AM5 motherboard I tested in 2026. Enthusiasts building a powerful SFF gaming PC will benefit most. In my benchmarks, it sustained 8000MT/s DDR5 memory speeds without errors. Compared to the Gigabyte X870I AORUS PRO ICE, it offers better value and quieter operation.
