Power Consumption

For testing power consumption, we took our test system and plugged it into a Kill-A-Watt power meter. For idle numbers, we allowed the system to idle on the desktop for 15 minutes and took the reading. For load numbers we measured the peak wattage used by the system while running the OpenGL benchmark FurMark 1.8.2 at 1280x1024 resolution.

Total System Power Consumption Results

Power Consumption Results: The AMD Radeon HD 6990 is pulling 499 Watts at the wall. At first glance that seems excessive. If we compare it to what the pair of AMD Radeon HD 6970's is pulling, it will make us feel a little better. Under full load with Furmark 1.8.2 the of AMD Radeon HD 6990 draws nearly 100 Watt's less than the pair of AMD Radeon 6970's and the pair of NVIDIA GeForce GTX 580's in SLI. Idle numbers for the AMD Radeon HD 6990 and the pair of AMD 6970's in CrossfireX are both sitting pretty at 132 Watts at the wall which is only 21 Watts more than a single AMD Radeon HD 6970.
