730-W Power Supply
The table below lists the total wattage available from the power subsystem for each voltage. If you
configure your system heavily, ensure that your loads do not exceed the combined total wattage of
730 Watts. For information about calculating the power usage for your configuration, see page 64.
Table 5. 730-W Power Supply System Output Capability
Voltage Maximum Current
+3.3 V 24 A
+5.0 V 24 A
+5 V Standby 2 A
+12.0 48 A
–12.0 V 0.5 A
CAUTION
Do not exceed a combined power output of 140 Watts for the +5 V and +3.3 V
outputs. Exceeding a combined 140 Watts 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 Watts for any one slot. The
average current usage per slot should not exceed 13 Watts.
