ƒ200-240 V∼ at 50/60 Hz; 3.4 A max.

520-W Single Power Supply Output Voltages

The table below lists the total wattage available from the power subsystem for each voltage. Ensure that your loads do not exceed the combined total wattage of 520 Watts. For information about calculating the power usage for your configuration, see “Calculating Power Usage.”

Table 4. 520-W Power Supply System Output Capability

Voltage	Maximum Current
+3.3 V	16 A
+5.0 V	16 A
+5 V Standby	2 A
+12.0 V	58 A
–12.0 V	0.5 A

1.Maximum continuous total DC output power should not exceed 520W. 520W includes the two fans powered from the power distribution board.

2.3.3V and 5V power is converted from 12V on the power distribution board.

CAUTION

Do not exceed a combined power output of 100 Watts for the +5 V and +3.3 V outputs. Exceeding a combined 100 Watts will overload the power subsystem and may cause the power supplies to overheat and malfunction.
