The 12V rail’s OCP triggering points are conservatively set since this is a powerful PSU, so there is no need to push it further. Moreover, there is an adequate difference between this rail’s cold and hot OCP triggering points. On the contrary, the minor rails have highly set OCP triggering points, with no significant differences between cold and hot conditions. In the 3.3V rail the OCP triggering point is precisely the same! Lastly, given the platform’s capabilities, the over power triggering point is set correctly.

  1. I was also waiting for this source, but on Aris’s advice I chose the superflower leadex vii 1200 platinum and I am very happy, better price and better performance, you couldn’t ask for more, in this case Seasonic has not released an excellent product like others times
