6.4Output Power/Currents

STATUS

Recommended

The following tables define the power and current ratings for two recommend power levels. Depending upon the system design, the power supply modules may have only three outputs (+12V, -12V, and 5VSB) or the full five outputs (+3.3V, +5V, +12V, -12V, and 5VSB). If only three outputs are provided from the module, the cage shall have additional DC/DC converters to generate +5V and +3.3V from the +12V provided by the modules. The combined output power of all outputs from the cage shall not exceed the rated output power. The power assembly shall meet both static and dynamic voltage regulation requirements over the full load ranges. The power sub-assembly shall supply redundant power over the full load ranges.

Table 11: 350 W Load Ratings

Voltage	Minimum Continuous	Maximum Continuous	Peak
+3.3 V 7	0.5 A	20 A
+5 V 7	2.0 A	20 A
+12V2 (baseboard connector)	0.5 A	12 A	15 A
+12V3 (peripheral connectors)	1.0 A	13 A	15A
-12 V	0 A	0.5 A
+5 VSB	0.1 A	2.0 A

1Maximum continuous total DC output power should not exceed 350 W.

2Maximum continuous combined load on +3.3 VDC and +5 VDC outputs shall not exceed 115 W.

3Maximum Peak total DC output power should not exceed 410 W.

4Peak power and current loading shall be supported for a minimum of 10 second.

5Maximum combined current for the 12 V outputs shall be 25 A.

6Maximum 12V combined peak current shall be 30A.

7The 3.3V and 5V may be supply by the module or DC/DC converters powered from +12V in the cage.

+12V3 (peripheral connectors)	0.5 A	10 A	16 A
-12 V	0 A	0.5 A
+5 VSB	0.1 A	2.0 A

1.Maximum continuous total DC output power should not exceed 480 W.

2.Maximum continuous combined load on +3.3 VDC and +5 VDC outputs shall not exceed 115 W.

3.Maximum Peak total DC output power should not exceed 620 W.

4.Peak power and current loading shall be supported for a minimum of 10 second.

5.Maximum combined current for the 12 V outputs shall be 37 A.

6.Maximum 12V combined peak current shall be 46 A.

7.The 3.3V and 5V may be supply by the module or DC/DC converters powered from +12V in the cage.
