I love MSI but faulty 3.5 minijacks suck. - The rear 3.5mm where I plug my speakers was behaving oddly, turned out the entire right channel was not producing sound. Wasted hours on this, eventually stripped the jacket and spliced a good half inch of wiring and tried again. This time there was QUIET sound. Progress... AI online tells me to do the "swap" where I try the spliced cables in the opposite channel to see if it works, thus eliminating the spliced wiring as the problem. Turns out it was right. Then the AI told me to start Soldering crap and prepping the motherboard for surgery when I gave it the middle finger and just pulled it from the 3.5mm jack in the back, and fit it into the front panel one. It worked perfectly with no loss to sound fidelity or issues with quality. Stupid.

Write a reviewGreat simple cheap motherboard - Great mother board does support my ryzen 7 9800x3d
Msi b850 - Very clean and inexpensive and comes with everything pretty much
Goo Replacement Board - My computer board stopped working. I purchased this a few months ago and my system has been working since. This was my first time ever swapping a board so I was surprised it actually worked haha.
Great motherboard - MSI always puts out a great motherboard have bought well over 50 MSI motherboards and have had zero issues with any of them. Well built several options good overclocking easy bios access and easy to manage things within the BIOS , hands down best motherboards I've ever worked with even over as Asus motherboards.
Very good motherboard - This motherboard is very good for the ryzen 9 series
Wifi Card Issues - I bought this motherboard back of January 2026, and by now late April I'm looking at having to pay to ship this motherboard again for RMA for the wifi card. At some point on PC startup, the Qualcomm Fastconnect 7800 wifi 7 card completely disappears from Device Manager, and my Linux OS doesn't show it connected anymore. It is physically inaccessible on the board without taking it apart, which would be an issue warranty-wise. I had sent it and received it back fixed about 3 weeks ago, and again I'm randomly having the same issue. Other than this issue, the board is nice to use, the bios is straightforward, and it has a clean look. In my opinion though, this quality issue with the wifi card makes me not want to buy another MSI product.
unwanted - unknown never used it, was a board you used to replace mine didnt want it
Great performance - Great board and super fast with a Samsung Evo 990 plus. Also the flash buttons come in handy. Released last year so this board and plenty of years of support. FYI, the Bequiet dark rock cooler clears the ram.
Easy install, good performance. - For the price this was a really good deal. The setup was extremely easy, the connections are good, and the wifi works exceptionally well. Would recommend!
