Power Consumption
The power consumption values were measured using the following test setup:
•
conga-PA3 SBC
•
LCD monitor
•
conga-PA3 cooling solution
•
Windows 7 (64-bit)
Note
All peripherals were powered externally and therefore did not influence the measured values.

Power States
System State
Description
S0: Minimum value
Sets the SBC to lowest frequency mode (LFM) with minimum core voltage during desktop idle. In this state,
the CPU is stressed to its maximum frequency.
S0: Maximum value
Sets the SBC to highest frequency mode (HFM/Turbo Boost). In this state, the CPU is stressed to its
maximum frequency.
S0: Peak value
Highest power spike during the measurement of “S0: Maximum value”. This state shows the peak value
over a short period of time (worst case power consumption value). Consider this value when designing the
system’s power supply to ensure that sufficient power is supplied during worst case scenarios.
S3
SBC is powered by 12V.
Processor Information
