Great motherboard with Real WiFi 7 (320 MHz)
Really happy with this motherboard. The build quality is excellent and setup was easy. Everything worked immediately without any fuss. The WiFi 7 actually delivers the 320 MHz bandwidth they advertise, got 3.4 Gbps and there is a desk and a wall between the PC and the router (Access point), unlike some other boards (starting with A, ending with S) I've tried which only had 160 MHz :/ . With PCIe 5.0 and several fast M.2 slots, it should handle upgrades to come. The BIOS is easy to use and I had no trouble getting my RAM running at full speed. I like the clean design and all the connectivity options - lots of USB ports. No strange issues with my Ryzen processor or Radeon graphics card. Temperatures stay reasonable, it runs quietly, and building with it was straightforward (first time since the being box area for that I did a build) If you need a solid AM5 motherboard that covers all the essentials without cutting corners on quality, this one's worth considering. I'd definitely recommend it.

Esthetically great looking, great quality!
Looks beautiful, seems to be great quality but customer service is lacking unless you get the right person to answer. I bought this for my first custom build and have had issues with the BIOS and fan control, the fans were set to full blast out of the box and I'm a complete novice so not familiar with how to safely set fan curves. Installed MSI center, set the cooling wizard to follow MSI protocol and tried the follow BIOS, worked great until i restarted computer. Called MSI and they just told me my computer had custom fan curves and was staying super cool so don't mess with it even though it sounds like a helicopter. OK, well I figured out that MSI center was not enabled for startup, enabled it and still same issue. Uninstalled MSI center and fans still stay very ramped up, I'm guessing around 1,500 rpms. Customer service was excellent other times I've called but seems to be very hit or miss. The one guy knew less then me and that's very low bar. Overall i would definitely buy this or look at Asus, their user interface is better. Radeon 9060 xt, Ryzen 5 9600x, Corsair rx850x psu, Corsair 32gb ram 6400 with cl32, 1tb samsung pro

Mother of MOBOs
This motherboard does the job for a really good price. Wifi 7 capable and new PCIe 5.0. Recommend if you're replacing your current MOBO or building a new PC.
