Power Supply Specification
670-W Single Power Supply Input Voltage
 100-127 V at 50/60 Hz; 12 A max.
 200-240 V at 50/60 Hz; 7 A max.
670-W Single Power Supply Output Voltages
The following table lists the total wattage available from the power subsystem for each voltage. Ensure your
loads do not exceed the combined total wattage of 670 W. For information about calculating the power usage
for your configuration, see “Calculating Power Usage.”
Table 5. 670-W Power Supply Output Capability
Voltage Maximum Current
+ 3.3 V 24 A
+5 V 30 A
+12 V1 16 A
+12 V2 16 A
+12 V3 16 A
+12 V4 16 A
-12 V 0.5 A
+5 VSB 3.0 A
WARNING
Do not exceed a combined power output of 170 W for the +5 V and +3.3 V outputs. Exceeding a
combined 170 W will overload the power subsystem and may cause the power supplies to overheat
and malfunction.
The expansion slots on the server board are rated for no more than 25 W for any one slot. The
average current usage per slot should not exceed 13 W.
750-W Hot Swap Power Supply Input Voltages
 100-127V at 50/60 Hz; 12 A max.
 200-240 V at 50/60 Hz; 6 A max.
750-W Hot Swap Power Supply Input Voltages
The following table lists the total wattage available from the power subsystem for each voltage. If you configure
your system heavily, ensure your loads do not exceed the combined total wattage of 725 Watts. For
information about calculating the power usage for your configuration, see “Calculating Power Usage.”
