The following table lists the total wattage available from the power subsystem for each voltage. Ensure that your loads do not exceed the combined total wattage of 670 Watts. For information about calculating the power usage for your configuration, see “Calculating Power Usage” on page 65.

Table 6. 670-W Power Supply Output Capability

Voltage	Maximum Current
+3.3 V	24 A
+5.0 V	30 A
+5 V Standby	3 A
+12.0	48 A
-12.0 V	0.5 A

Warning: Do not exceed a combined power output of 170 Watts for the +5 V and +3.3 V outputs. Exceeding a combined 170 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.
