★★★★★Best AM5 itx board currently out
The ROG Strix B850-I is a powerhouse in a compact form. Despite its mini-ITX size, it delivers excellent performance, strong VRMs for stable overclocking, and plenty of features packed into a small board. Wi-Fi 7, PCIe 5.0 support, and solid cooling solutions make it future-proof, while the sleek ROG design keeps it looking premium. Ideal for small-form-factor builds that don’t want to compromise on power.

★★★★★Future proof mITX motherboard.
Booted on the first attempt and going on and strong. Never had to fiddle with anything. Transferring drive with windows 11 from my older x570 rig was a bit of a hassle. But that’s part of DIY PC hobby. Tons of usb ports(8nos), great quality aluminum heat sinks for the VRMs and onboard connectivity options, PCIe 5.0 X16 slot and M.2, wifi7. This thing is future proof till 2030. At $300 it’s the cheapest I’ve seen this board go on sale. I think it’s a steal in this economy. Highly recommended.

★★★★★Poor NVMe Gen 4 compatibility.
This board can't recognize the Samsung 990 Pro as a bootable device, despite recognizing it as a storage device. Tried every solution I can find on the internet (disabling csm, set speed to Gen4, updated to latest motherboard firmware/bios). Nothing worked.

★★★★★zero issues
I’ve been using the ASUS ROG Strix B850‑I Gaming WiFi motherboard for a while now, and it’s still running strong with zero issues. The board has been stable, fast, and reliable with my AM5 setup. BIOS updates have been smooth, memory support has been solid, and thermals stay under control even in a compact Mini‑ITX build.
