Power Consumption
The goal of this description is to provide a method to calculate the power consumption for the
CP605 baseboard and for additional configurations. The Pentium 4 processor dissipates the
majority of the thermal power.
The power consumption tables below list the voltage and power specifications for the CP605
board and the CP605 accessories. The values were measured using an 8-slot passive Com-
pactPCI backplane with two power supplies: one for the CPU, and the other for the hard disk.
The operating systems used were DOS and Windows
®
2000. All measurements were conduct-
ed at a temperature of 25°C. The measured values varied, because power consumption was
dependent on processor activity.
The following table indicates the power consumption using Windows
®
2000, IDLE Mode, VGA
resolution 1024x768.
