    1.0 out of 5 stars Lack of support from MSI
    By Paul Smith on 17 July 2020
    The board looks lovely and has nice features at a good price and would easily get 5 stars if it worked.
    Sadly, mine doesn't (it won't POST). The board is too new for any advice or troubling shooting hints to be available on the interwebs or the forums which means you are stuck using MSI support which is not a pleasant or productive experience. It has EZDebug lights (you can see one lit just above the 24pin connector) which you would think were there to help work out what was going wrong, but alas... nobody seems to know what they actually mean. The BIOS is being activley worked on which is normally a good sign, it went from Beta 13 to A1 during the week, but there are no changelogs that I can find which doesn't help.

    I tried to RMA the board through MSI but they are not playing ball so I am just going to have to return it to Amazon and get something else instead.
