Chapter 4. Power Supply
Component Outputs
The power supply provides separate voltage sources for the system board and internal storage devices.
The following figures show the approximate power that is provided for specific system components. Many
components draw less current than the maximum shown.
Note: For each PCI connector, the maximum power consumption is rated at 25 watts for +5 V ac and
+3.52 V ac combined.
