3.2.6 DC Output Specification
3.2.6.1 Output Power/Currents
The following table defines the output current ratings. Each output has a maximum and
minimum current rating shown in Table 21. The power supply shall meet both static and
dynamic voltage regulation requirements for the minimum dynamic load conditions. The power
supply must meet only the static load voltage regulation requirements for the minimum static
load conditions.

The combined output power of all outputs shall not exceed 405W @100~127VAC.
3.2.6.2 Standby Output
The 5VSB output should be present when an AC input greater than the power supply turn on
voltage is applied.
3.2.7 Protection Circuits
The 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.
3.2.7.1 Current Limit (OCP)
The 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 OCP limit is removed.
