The PSU didn’t shut down in any of the OCP tests I conducted, so I am skeptical about the official specs. Moreover, I measured low voltages at 12V3 and 12V4, so I can safely assume that this rail would drop below 11.4V at higher loads. Nonetheless, this is permitted by the ATX 3.0 spec, which allows down to 11.2V. Moreover, OCP is set high on the minor rails, especially at 3.3V. On the contrary, over power protection is set conservatively, but I want to see a lower limit at higher temperatures.
