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 or ISA connector, the maximum power consumption is rated at 10 watts for +5 V DC
and +3.3 V DC combined. Typical power budget assumptions use 7.5 watts per adapter. If
maximum power is used, then the overall system configuration will be limited in performance.
