Total System Power Consumption & Acoustics
It's All About the Watts and Decibels
As you can see, the DDR2-equipped P35 motherboard consumed the least amount of power both while idling and under load. Somewhat surprisingly, the Gigabyte X38-DQ6 had the second lowest power consumption while idling, only to surge to the head of the pack while under load. We suspect the X38-DQ6's power characteristics are a reflection of its relatively large number of integrated peripherals and not simply the result of the X38 consuming more power then the P35. In fact, looking at the P5E3 Deluxe vs. P35-DDR3 comparison, we'd say the X38, despite having more features and PCI Express lanes actually consumes about the same amount of power as the P35.
