The OCP triggering points are correctly set at 12V, but this is not true for the minor rails where OCP is sky-high, especially at 3.3V. There is no need for such high amperage at 3.3V. On the other hand, OPP is correctly set. All other protection features are present and work well.

  1. Is the included 12VHPWR cable sufficient/safe for powering an RTX 4090 FE or should a 3×8 cable/adapter still be used? If it is sufficient and totally safe, does the manual specify which ports to use or doesn’t that matter?
