Power Consumption
The power consumption values were measured with the following setup:
• conga-QA6
• modified congatec carrier board
• conga-QA6 cooling solution
• Microsoft Windows 7 (32 bit)
Note
The CPU was stressed to its maximum workload with the Intel

Measurement Description
The power consumption values were recorded during the following system states:
System State
Description
Comment
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).
The CPU was stressed to its maximum frequency.
S0: Peak value
Highest current spike during the measurement of “S0: Maximum value”.
This state shows the peak value during runtime
Consider this value when designing the system’s power supply to
ensure that sufficient power is supplied during worst case scenarios.
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.
