Power Consumption of the system will be measured in both idle states and loaded states and will take into account the peak voltage of the system with each video card installed. I will use MSI Kombuster to load the GPU for a 15-minute test and use the peak load of the system as my result for the maximum load. The idle results will be measured after 15 minutes of inactivity on the system. For load testing the GTX 500 series, I will once again use Crysis Warhead run at 2560 x 1600 using the Gamer setting with 8xAA looping the Avalanche benchmark scenario.

- 1920 x 1200 Resolution
- 15-minute load test
- 15-minute idle test
- Measurement is in Watts
Lower = Better
The Load testing at both stock and overclocked speeds shows the HD6770 in the middle of the pack with the HD6750 using less power, followed by the HD6670s using the least amount of power.
