22 NetVista™ Technical Information ManualNote: The total combined 3.3 V and 5 V power must not exceed 100 watts.Note: The total combined 3.3 V and 5 V power must not exceed 65 watts.Component outputsThe power supply provides separate voltage sources for the system board andinternal storage devices. The following figures show the approximate power that isprovided for specific system components. Many components draw less current thanthe maximum shown.Output protectionThe power supply protects against output overcurrent, overvoltage, and short circuits.See the power supply specifications in Chapter 4, “Power supply,” on page 21 fordetails.+12 volts +5% to −5% 0.2 A 4.2 A+3.3 volts ±5% 0.2 A 12.0 A−12 volts ±10% 0 A 0.4 A+5 volts (auxiliary) +5% to −5% 5 mA 2.0 ATable 6.
