2.5.5.4 Output Power / Currents
The following table defines power and current ratings for this 400W power supply. The
combined output power of all outputs does not exceed the rated output power. The power
supply meets both static and dynamic voltage regulation requirements for the minimum loading
conditions.
Table 111. Load Ratings
Parameter Min Max. Peak Unit
5V 0.3 20.0 A
12V1 1.0 16.0 A
12V2 1.0 16.0 A
3.3V 0.5 20.0 A
− 12V 0.0 0.5 A
5Vstb 0.0 2.5 A
Notes:
1) Max combined power of 12V1 and 12V2 shall not exceed 350W.
2) Max combined power on 3.3V and 5V equal to 130W with current values not
exceeding max values of load condition
3)+5V/3.5A,+12V/30A and +5V/8A,+12V/5A load combination will be used for cross load
regulation
2.5.5.5 Voltage Regulation
The power supply output voltages are within the following voltage limits when operating at
steady state and dynamic loading conditions. These limits include the peak-peak ripple/noise.
All outputs are measured with reference to the return remote sense signal (ReturnS).

2.5.5.6 Dynamic Loading
The output voltages are within the limits specified for the step loading and capacitive loading
requirements specified in the following table. The load transient repetition rate is tested between
50 Hz and 5 kHz at duty cycles ranging from 10%-90%. The load transient repetition rate is only
a test specification. The Δ step load may occur anywhere within the MIN load and MAX load
conditions.
