*The combined output power of all outputs shall not exceed 405W @100~127VAC.
3.1.7.2 Standby Output
The 5VSB output should be present when an AC input greater than the power supply turn on
voltage is applied.
3.1.8 Protection Circuits
Protection circuits inside the power supply should cause only the power supply’s main outputs
to shut down. If the power supply latches off due to a protection circuit tripping, an AC cycle
OFF for 15sec and a PSON# cycle HIGH for 1sec shall be able to reset the power supply.
3.1.8.1 Current Limit (OCP)
Following are the over current protection limits for each output. For testing purposes, the
overload currents of each tested output rail should be ramped at a minimum rate of 10 A/sec
starting from full load. If the current limits are exceeded, the power supply should shut down and
latch off. The latch will be cleared by toggling the PSON# signal or by an AC power interruption.
The power supply should not be damaged from repeated power cycling in this condition. 5VSB
must be protected under over current or shorted conditions, so that no damage can occur to the
power supply. 5Vsb will be auto-recovered after removing OCP limit.

3.1.8.2 Over Voltage Protection (OVP)
The power supply over voltage protection should be locally sensed. The power supply must shut
down and latch off after an over voltage condition occurs. This latch shall be cleared by toggling
the PSON# signal or by an AC power interruption. Table 14 contains the over voltage limits. The
values are measured at the output of the power supply’s pins. The voltage should never exceed
the maximum levels when measured at the power pins of the power supply connector during
any single point of fail. The voltage should never trip any lower than the minimum levels when
measured at the power pins of the power supply connector. 5VSB will be auto-recovered after
removing the OVP limit.
