power supply will not be damaged from repeated power cycling in this condition. 12VSB will be
auto-recovered after removing OCP limit.

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 will be cleared by toggling the
PSON# signal or by a DC power interruption. The values are measured at the output of the
power supply’s connectors. The voltage will never exceed the maximum levels when measured
at the power connectors of the power supply connector during any single point of fail. The
voltage will never trip any lower than the minimum levels when measured at the power
connector. 12VSB will be auto-recovered after removing OVP limit.

Over Temperature Protection (OTP)
The power supply is protected against over temperature conditions caused by loss of fan
cooling or excessive ambient temperature. In an OTP condition the PSU will shut down. When
the power supply temperature drops to within specified limits, the power supply will restore
power automatically, while the 12VSB remains always on. The OTP circuit has built-in margin
so that the power supply will not oscillate on and off due to temperature recovering condition.
The OTP trip level has a minimum of 4°C of ambient temperature margin.
