OCP on the minor rails looks to be set low, given our experience so far. Initially, the 5V rail didn't have a problem delivering over 40A. But it started to degrade after a short period, and in the end it only worked properly with 24.5A. The same held true for the 3.3V rail.
OTP is set very high in our opinion, since we had to apply a huge thermal load on the secondary side to trigger it. The bulk cap's external casing nearly melted during our OTP evaluation.
