  • Plenty of features, be cautious with a 9800x3d.
Had no issues but with the 9800x3d asrock concerns a few months back, I did not want to risk any issue. Board was packed with features and was stable.

  • Broad set of features for the price
This motherboard is the best budget board I've got. It has many connectors inside for all the functionality and customisation one can want. Overclocking is very easy as well, with an easily accessible setting to enable my 9700X to use 105 watts.

  • Stay away
Stay away from this, there is something up with the seller or asrock. Should have been suspicious when I saw it was frequently returned. Couldn't post with this, wasted a day trying to debug. Plus there was that whole thing with 9000 series ryzens getting fried. Got a new board and it posted on my frist attempt. ... show more

  • Bluetooth module died
After a week of usage with my Ryzen 7 9700x the Bluetooth started failing and then it wouldn't work at all.

  • DO NOT BUY
The board looks nice and has built in RGB…that’s where the positives stop. Apparently these have voltage spikes and don’t work well with AMD even though it’s advertised to work. The entire system had a lag no matter what I did. Waited about an hour just for windows to install. The computer shut down randomly multiple times before I researched the issues with AMD CPUs and this brand. Switched the Mobo to MSI and it’s ran smooth since. Avoid this trash. ... show more
