Intel® Server Chassis SC1400UP / Intel® Server Platform SR1425BK1-E
Note:
1.
Maximum continuous total DC output power should not exceed 300 Watts.
2.
Peak total DC output power should not exceed 350 Watts peak.
3.
Peak power and peak current loading shall be supported for a minimum of 12 seconds.
4.
Combined 3.3V/5V power shall not exceed 100W.
6.22.1 Standby Outputs
The 5VSB output shall be present when an AC input greater than the power supply turn on
voltage is applied.
6.22.2 Fan-less Operation
Fan-less operation requirement is the PS ability to work indefinitely in Stand-By mode: w/ power
on, PS off and the 5VSB at full load (=2A) under the environmental conditions (temperature,
humidity, altitude). In this mode the components' max temperature should follow the component
de-rating guidelines.
6.23 Voltage Regulation
The power supply output voltages must stay 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 5V,
12V, –12V and 5VSB outputs are measured at the power supply connectors referenced to
ReturnS. The +3.3V is measured at it remote sense signal (3.3VS) located at the signal
connector.

6.23.1 Dynamic Loading
The output voltages shall remain within limits specified for the step loading and capacitive
loading specified in the table below. The load transient repetition rate shall be tested between
50Hz and 5kHz at duty cycles ranging from 10%-90%. The load transient repetition rate is only
a test specification. The ∆ step load may occur anywhere within the MIN load to the MAX load
conditions.
