The PSU shuts down with 77.82A on its +12V rail. We suspect that this is not because of over-current protection on this rail, but due to under-voltage protection.
In our opinion, this PSU's over-power protection is set too high; it should kick in at around 120-125% of the maximum-rated capacity to keep the +12V rail within spec.
Over-temperature protection has a pretty high triggering point, too. This is something we've encountered in plenty of semi-passive PSUs.
