PC 300 GL and 300 PL
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 5 watts
for +5 V dc and +3.3 V dc combined.
If maximum power is used, the overall
system configuration will be limited in performance.
