Power Consumption
The power consumption values were measured with the following setup:
• Input voltage +12 V
• conga-TCA3 COM
• modified congatec carrier board
• conga-TCA3 cooling solution
• Microsoft Windows 7 (64-bit)
Note
The CPU was stressed to its maximum workload.

Measurement Description
The power consumption values were recorded during the following system states:
System State
Description
S0: Minimum value Lowest frequency mode (LFM) with minimum core voltage during desktop idle The CPU was stressed to its maximum frequency
S0: Maximum value Highest frequency mode (HFM/Turbo Boost).
S0: Peak value
Highest current spike during the measurement of "S0: Maximum value". This
state shows the peak value during runtime
S3
COM is powered by VCC_5V_SBY
S5
COM is powered by VCC_5V_SBY
Note
1. The fan and SATA drives were powered externally.
2. All other peripherals except the LCD monitor were disconnected before measurement.

The CPU was stressed to its maximum frequency
Consider this value when designing the system's power supply to
ensure that sufficient power is supplied during worst case scenarios
