1.  The delay means that the 12V3/12V4 OCP circuits will allow the peak load of 24A/25A for 0.5 sec minimum before 
it will shut down the power supply, respectively. 
2.5.9.2 
Over-voltage Protection (OVP) 
The power supply over-voltage protection is locally sensed. The power supply will shut down 
and latch off after an over voltage condition occurs. This latch can be cleared by toggling the 
PSON
#
 signal or by an AC power interruption. The following table contains the over-voltage 
limits. The values are measured at the output of the power supply’s pins. The voltage never 
exceeds the maximum levels when measured at the power pins of the power supply connector 
during any single point of fail. The voltage will not trip any lower than the minimum levels when 
measured at the power pins of the power supply connector. The +5VSB rail will auto-recover 
after its OVP limit.
