Everything works fine.
Motherboard is great. My last PC was huge so I decided to downsize. Has all the features i was looking for. Wifi might not work until you update drivers and windows.Biggest issue, not really an issue, inconvenience! i thought for sure on first start msi is supposed to start a program to update drivers. That wasn't the case. Just be prepared to be hardwired on to your internet searching for the drivers online.But well worth it!
