The 12V rail’s OCP triggering points are correctly set, but this is not the case for the minor rails where the corresponding OCP triggering points are set sky-high. At least, there is a difference between normal and hot conditions. The over power protection is set high enough, and the corresponding triggering point drops enough at high temperatures. Finally, the other essential protection features are present and work well, with only fan failure protection missing.

    It’s nice to see that there is so much optimism and imagination around.
    This should lead to improvement.
