9.2.2 Power Supply DC Output Requirements
This section is for reference purposes only. Its intent is to provide guidance to system architects
planning to use the Intel
®
Server Board S5400SF in a custom chassis for which a power supply
is to be determined. The contents of this section specify the power supply requirements Intel
used to develop a 600 Watt power supply for its 1U server platform. The values used to
determine a custom chassis power supply is dependent on the intended system configuration to
be supported.
The combined power of all outputs does not exceed the rated output power of the power supply.
The power supply must meet both static and dynamic voltage regulation requirements for the
minimum loading conditions.
Table 84. 600 W Load Ratings
Voltage Minimum Continuous Maximum Continuous Peak
+3.3 V 1.5 A 20 A
+5 V 1.0 A 24 A
+12 V1 0.5 A 16 A 18 A
+12 V2 0.5 A 16 A 18 A
+12 V3 0.5 A 16 A
+12 V4 0.5 A 16 A
-12 V 0 A 0.5 A
+5 VSB 0.1 A 3.0 A 3.5 A
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 49 A.
3. Maximum continuous load on the combined 12 V output should not exceed 44 A.
4. Peak total DC output power should not exceed 650 W.
5. Peak power and current loading should be supported for a minimum of 12 seconds.
6. Combined 3.3 V and 5 V power should not exceed 150 W.
9.2.3 Power-on Loading
The power supply should operate at lighter load conditions when the system first powers on.
Under these conditions, the voltage regulation limits are relaxed. The power-on loading and
voltage regulation requirements are listed in the following table.
Time duration is 1 second during power on.
