( 1 ) +3.3V & 5V total output not exceed 125W.
( 2 )Total output continuous shall not exceed 300W watts.
( 3 )+12V Peak current is 19A(less then 10m Sec.),minimum voltage during peak is >10.8Vdc.
( 4 )5Vsb Peak current is 3A(less then 500m Sec.), minimum voltage during peak is > 4.5Vdc.
( 5 )maximum combined current for the 12V outputs shall be 22A.
Voltages and ripple are measured at the load side of mating connectors with a 0.1 uF monolithic
ceramic capacitor paralleled by a 10 uF electrolytic capacitor across the measuring terminals.
4.2. LOAD CAPACITY SPECIFICATIONS
The cross regulation defined as follows, the voltage regulation limits DC include DC Output
ripple & noise.

4.3. HOLD-UP TIME (@FULL LOAD)
115V / 60Hz : 17 mSec. Minimum.
230V / 50Hz : 17mSec. Minimum.
The output voltage will remain within specification, in the event that the input power is removed or
interrupted, for the duration of one cycle of the input frequency. The interruption may occur at any
point in the AC voltage cycle. The power good signal shall remain high during this test.
