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

I didn't understand some features until I went to ASUS' site and looked at every feature and its description there. Explanations aren't in the manual for how the hardware works. For example: the EF Fan header is not Exhaust Fan Fan like I thought, it is Extra Flow Fan. Just an extra chassis fan header, I guess. I did have to replace the thermal pads on the M.2 slot, they were too thin and too slim (narrow). 1mm pads worked fine for my 4Tb Crucial T500 drive I put there. I wish the second M.2 slot were mounted on a 1/4" standoff from the back of the board, my temps are 58 for the 4Tb WD SN850X I have there but the drive is so close to the board that I can't fit a heatsink on it and I can't get much air circulating on that side of the board. I did try a big file transfer and it had no effect on that drive's temperature. I've only had this a week and I've got a long ethernet cable to my router to facilitate the setup and the transfer of files from the PC I'm displacing to bedroom status for this one. I mention that to say I have the wifi setup but haven't used it but for a few minutes. I was confused that it was on 5G instead of 2. 4G since it is some distance from the router but maybe that's something to do with WIFI 7 at both ends, the router and this board? Dunno. Oh, and back to the ethernet, 2.5G ethernet at both ends is great. I was downloading a steam game that Steam predicted would take 2 hours and 20 minutes to download. After just a minute Steam suggested it would go faster if I turned on the other PC on my network. I went and flipped that switch. When I got back it was transferring the files instead of downloading. It took just 19 minutes, one seventh of the time or 7 times my ISPs speed of 300 some gbps. Great improvement. Maybe it's time to cable my house and get fiber.

Motherboard is great so far has all the features that you would need for a modern motherboard in 2026 only downside is it holds two stick of ram but my PC build is strictly for gaming. You can get two 128 gb DDR5 if you really need it lol

Llego en el tiempo estipulado y en excelente estado.

Poor stability. PC takes 1-3 minutes to turn on and sometimes not at all. Everytime I turn it on windows says "something happened, reset your pin". I have done extensive troubleshooting and nothing fixed it. The drivers dont have gui/window when you double click to install, I have no way of knowing when it's done or not. New MSI motherboard fixed the problem completely, instant boots and no issues. Also when I stalled the drivers a GUI appeared like its supposed to.

Took a little fanagling but it eventually worked out. Great bit of hardware for your Mini-ITX build. Fit this into the KKSB K1 case from Kickstarter Years ago. It's like 7L of room. Very compact, and this motherboard had all the bells and whistles I wanted for the full PCIe 5 Go around. PCIe Riser Cable is even 5. This Motherboard is smooth, and thee ASUS BIOS has always been user-friendly in my mind compared to some others I've used in the past. Grab one now!

As a compact yet powerful Mini‑ITX board, the Strix B850‑I genuinely impresses. ASUS has managed to cram a wealth of advanced features into a tiny 17 × 17 cm form factor—two PCIe 5.0 M.2 slots, a PCIe 5.0 x16 SafeSlot, up to 96 GB of DDR5 memory (OC beyond 8,400 MT/s), and robust 10 + 2 + 1 power phases rated for 70 A per stage—ideal for pushing Ryzen 7000/8000/9000 CPUs to their limits. What really sets this board apart is its connectivity and build quality: a 20 Gbps USB‑C port, five 10 Gbps USB ports, HDMI 2.1, Wi‑Fi 7, 2.5 Gb Ethernet, SupremeFX ALC4080 audio backed by a Savitech amp, and tidy DIY‑friendly touches like Q‑Latch and pre‑mounted I/O shield. ASUS’s AI Suite—offering AI Overclocking, Networking II, and Advisor—simplifies fine-tuning even for novices. Overall, it's a “premium mini-ITX marvel”. Strengths 👍 * Specs-to-size: Dual PCIe 5.0 M.2 and PCIe 5.0 GPU slot are rare in sub‑20 cm boards. * Power delivery: Strong VRM setup allows stable overclocking. * Port selection: No shortage of USB, high-speed networking, and modern video outputs. * User-friendly extras: Q‑releases, pre‑mounted shield, BIOS FlashBack, and RGB headers make building and upgrading simpler. Minor Drawbacks 👎 * Pricey: Positioned at the premium end of B850 boards (~$300+), rivaling even some X870 options. * Wi‑Fi module warts: Users report inconsistent performance with the MediaTek MT7925—ping spikes and lag under load, sometimes resolved only by swapping to an Intel AX210. * Audio quirks: The ALC4080 audio can misbehave—distortion/clipping on line-out unless front‑panel jack routines are manually disabled. Overall Verdict: If you're building a compact, performance-oriented, Ryzen-based rig and want bleeding-edge features like PCIe 5.0 and Wi‑Fi 7, the Strix B850‑I delivers in style and substance. It’s easy to assemble, well-appointed, and rock-solid in power delivery. However, that premium comes at a cost—not just in money, but in occasional wireless/audio quirks and the potential for coil whine. Why 4★? Because it offers top-tier specs, polished design, and future-proofing, but misses perfect marks due to some real-world annoyances and its elevated MSRP. In many cases, it’s an excellent choice—if the price fits and you don’t mind applying a few workarounds for connectivity and audio. Final Thoughts: ASUS hasn’t skimped on ambition here. The Strix B850‑I is a triumph in packing flagship tech into an ultracompact form—but if you’re sensitive to wireless dropouts, audio fidelity, or coil noise, budget in a Wi‑Fi card or DAC, or compare it to slightly cheaper boards like the ASRock Phantom or Steel Legend. Still, for a high-end Mini‑ITX build, this board nails almost everything it attempts.

RELIABLE MOTHERBOARD! Recently had the Aorus B650-i Ultra and it’s the worst board you can buy for reliability (took me a week to get it to post) after owning for a year it kept giving me issues so I finally said F it and wanted something more reliable and this board posted flawlessly took me a hour to put everything together and pressed the power button and I was in the bios in seconds. JUST BUY THIS BOARD TRUST ME! It’ll save you from your headaches

I want to really like this system, but some of their choices just make no sense and cause issues. Performance wise it does well and is what you expect for a B850 chipset. Where this design fails is when it comes to the little things that become a big problem. The "on board" audio is just a USB audio, and it is just really not good. I use an external DAC and even with that, it is just bad. So bad, I actually plugged in a USB SPDIF, and it worked better. The WIFI is horrible, as is the BT. Luckily I have LAN as it was bad. Again, even plugging in a cheap USB wifi was better. Then you have the design flaws with both the pcie gpu slot and the nvme slot. Both of which can cause damage if you don't read their special instructions. Honestly wishing I would have went with the Gigabyte at this point.

Received the item with perfect condition

asus klvalite, inga problem

Ich kann es bis jetzt empfehlen ein tolles Board - AM 5 Socket PCI .5 und WiFi 7 und für 2 M.2 Festplatten , ausser USB 4.0 . Ich habe mich für dieses aktuelle Mini-ITX Board entschieden statt ATX Board. Das einzige was mir aufgefallen ist ,das Bluetooth nur mit eingesteckter Antenne funktioniert, sonst lief alles Super und einwandfrei beim einrichten. Wenn es jetzt noch genausolange wie mein letztes hält ist es das Geld vielleicht dann auch Wert.

Excelente funcionamiento muy fácil de instalar e intuiciones muy claras hace perfecto match con todos mis componentes

Awesome mobo and works flawlessly. Glad it wasn’t tampered with like a lot of computer parts on Amazon.
