3. DC Output Specification
3.1 Output Current / Loading
The following tables define two power and current rating. The power supply shall meet both 
static and dynamic voltage regulation requirements for minimum load condition.
  
Single rail for +12V
Note 1: Maximum continuous total DC output power should not exceed 850 W.
3.2 DC Voltage Regulation, Ripple and Noise
The power supply output voltages must stay within the following voltage limits when operating 
at steady state and dynamic loading conditions. All outputs are measured with reference to the 
return remote sense (ReturnS) signal. The +5V,+3.3V, +12V, -12V and +5VSB outputs are 
measure at the power supply connectors references to ReturnS. The +5V and +3.3V is measured 
at its remote sense signal (+5VS, +3.3VS) located at the signal connector. 
Table 7 – Regulation, ripple and noise
Ripple and Noise shall be measured using the following methods:
a) Measurements made differentially to eliminate common-mode noise
b) Ground lead length of oscilloscope probe shall be    0.25 inch.
c) Measurements made where the cable connectors attach to the load.
d) Outputs bypassed at the point of measurement with a parallel combination of 10uF tantalum 
    capacitor in parallel with a 0.1uF ceramic capacitors.
e) Oscilloscope bandwidth of 0 Hz to 20MHz.
f) Measurements measured at locations where remote sense wires are connected.
g) Regulation tolerance shall include temperature change, warm up drift and dynamic load
3.3 Timing Requirements
These are the timing requirements for the power assembly operation. The output voltages must 
rise from 10% to within regulation limits (Tvout_rise) within 5 to 70mS. The +5V, +3.3V and +12V 
output voltages should start to rise at about the same time. All outputs must rise monotonically. 
The +5V output needs to be greater than the +3.3V output during any point of the voltage rise. 
The +5V output must never be greater than the +3.3V output by more than 2.25V. Each output 
voltage shall reach regulation within 50 mS (Tvout_on) of each other during turn on of the 
power supply. Each output voltage shall fall out of regulation within 400 mS (Tvout_off) of each 
other during turn off. Figure 1 and figure 2 show the turn On and turn Off timing requirement. In 
Figure 2, the timing is shown with both AC and PSON# controlling the On/Off of the power supply.
