Notes:
1. Maximum continuous total DC output power should not exceed 600 W.
2. Peak load on the combined 12-V output should not exceed 48 A.
3. Maximum continuous load on the combined 12-V output should not exceed 43 A.
4. Peak total DC output power should not exceed 660 W.
5. Peak power and peak current loading should be supported for a minimum of 12
seconds.
6. Combined 3.3 V/5 V power should not exceed 140 W.
2.1.5.6 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). The
+12V3, +12V4, –12V, and 5VSB outputs are measured at the power supply connectors
referenced to ReturnS. The +3.3V, +5V, +12V1, and +12V2 are measured at the remote sense
signal located at the signal connector.

2.1.5.7 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.
