ASUS ROG Strix B850-I Gaming WiFi AMD AM5 B850 Mini-ITX mITX Motherboard 10+2+1 Stages, DDR5, 2.5G LAN, WiFi 7, 2X M.2, PCIe® 5.0 x16, USB 20Gbps Type-C®, AI Overclocking, AI Networking II, Aura Sync

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.

So to be clear: I bought the renewed/used like new version of this MoBo, and this is my experience. I've been using this motherboard for a few days now on a brand new build, and everything is working smoothly and without issue. I was able to boot into Bios easily and make all the necessary adjustments with no major issues. The Bios that it came with is from October so about 8-9 months old, but it still worked right off the bat with my Ryzen 5 9600x, which was my major question. I didn't want to have to do a Flashback immediately before getting things up and running. When I got the package, everything looked as it would have if it were new, except that the anti-static bag the Mobo came in was taped closed, not necessarily factory sealed, but that's sort of irrelevant. I *believe* that it came with all of the extras/accessories/cables but honestly if it did, I would have liked more. There weren't any extra screws, other than the M.2 clip-screw replacements, and there weren't any extra cables, which would have been nice. The manual was there and looked new, and is not a bad manual when it comes to explaining all aspects of the function of the motherboard and features. Speaking of which, the rear ports are a great selection on this mobo, plenty of ports, everything working as they should, and the quality of the board seems great. Another reason I bought this motherboard was the SupremeFX audio codec on board, which as far as mid-tier motherboards go, seems to be a pretty good on-board audio setup. So far, with testing on intricate songs like Steely Dan's Aja and Daft Punk's Touch, the sound is amazing, very clear, multi-layered, and no static-y edge that I was getting in the past.Overall, I think this board is a steal at $160 in 2025, and I am happy to report no issues with a "used" or "renewed" motherboard.I will update this review if there are any major failures or issues.

Been running this board for almost a year now. I'll start with the build (was just an additional system for my computer room).This mobo.64gb Acer Predator Vesta II CL30 PC5 6000Two Samsung 990 PRO SSD (2tb each)AMD 9800X3D cooled by ASUS ROG Strix LC III 360Powercolor Red Devil 7900XTAll thrown together in the SSUUP Xhuttle case - Air flow - Bottom / Front IN - Topside ExhaustThe board has been flawless. CPU, GPU and RAM speed / throughput has been clean, without issue and top speeds.The board has excellent RAM capacity, fit perfectly in the case and although I disabled the WiFi, I did run it for a few days and it functioned flawlessly with my ASUS ROG Rapture WiFi 6 AX Gaming Router (GT-AX6000).It was all purchased here on Amazon, so if you're in the market for a super solid, top end gaming rig, here's your shopping list. Unless you're doing mad overclocking, a whole lot of tweaking, the bells, whistles and features of higher model boards are literally throwing money in the fire, when you could use it for fancier fans, or cables, etc.Highly recommend this board, Can't go wrong.Pay attention to detail and you're golden. I've been building for 35 years now, and I'm still just as meticulous now as I was on my first build. It pays off in the long run.I'm attaching a few awful pics. I did not take any for this review, these were just a couple pics I snapped for friends who asked. Never intended to share them, but alas, it gives you an idea of what my list comes out to be.

The media could not be loaded. So far it's great! I love love that for micro ATX you can get so much more for your money. I think it's a good happy medium between sfx and full ATX. I put this inside of a Jonsbo Z20. Just waiting on my GPU now. I got this because it was white and I wanted to have a full white build, but I also wanted to ensure my Gen 5 PCIE m.2 didn't share lanes and sacrifice performance. So far I'm loving it. I updated the BIOS using the BIOS flashback utility with ease. Just make sure you get the right bios file for the correct motherboard. This one shipped from the United States so I had to ensure that I was on the US site. It also has so many spots for m.2 storage, I have room for expansion if I ever wanted to. Love that. Overall build quality is as expected. I love how many USB a ports there still are, and it has two USBC ports. Installation was pretty typical as far as motherboards go. As expected, also be aware that AMD motherboards on the am5 platform typically take a while to post after a bios update or on the initial power on. Don't freak out, it's coming up.
