Gigabyte's Dynamic Energy Saver technology is what really sets this motherboard ahead of the competition. They boast that this software can help you achieve up to 70% less CPU power consumption as well as up to 20% improved power efficiency. What does this do to the actual physical motherboard? Well actually, not much. Gigabyte removed the 4-pin Molex connector to replace it with LEDs that light up to show you how significant your loading is. You can see the original motherboard on the left and the new motherboard with Dynamic Energy Saver on the right.
You can obtain the Dynamic Energy Saver software either on your included driver disc or on Gigabyte's website. After you install the software, you'll be prompted to restart so that the changes take effect. You'll need to press the "On" button once you load up the software.
You can think of the "Power Savings" readout like an odometer on a car. It just keeps on adding every bit of wattage you save so that you can see it over time. As you can see, it took me about two and half hours to save just over 22 watts. The higher you set the level of your CPU voltage under the "Dynamic Voltage" tab, the faster you'll see the "Power Savings" readout go up.
You can see the testing on this particular feature further into the review.
