Output Requirements

The following represent the output requirements of the 420-watt power
supply:

Ripple and noise bandwidth is from DC to 20 MHz.

+12V should provide 15 A surge current for the first 10 seconds after
power on, and this regulation should be within ±10%.

Total power consumption is 420 watts.

The table below shows the 420-watt power supply output requirements
(measured at output power connector).
