Easy to install. All the components fit properly. 4 stars only because I spent 2 hours figuring out that the motherboard was shipped with a BIOS that didn't support my CPU (Ryzen 5 8500G). I had to flash a BIOS update through a USB drive.
Recognissed all components and updated bios without any issues.
This is a great option for anyone looking to start building or upgrade to AM5.For it's price point, it features a lot of things that can make your build a fantastic one.It has really good support for fast DRAM frequency. It has 2 ARGB headers so if you daisy chain all your fans, you don't have to worry about being short on headers to control the RGB. Speaking of which, being an MSI board, MSI Mystic Light is really easy to use.Upon booting for the first time, you don't have to go on MSI's support website to download the necessary drivers (maybe I'm an old head, but that's how I always did it) as MSI will prompt you to download when you boot. The board itself doesn't look bad either.My build turned out perfect and way better than my previous AM4 build.
