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 1280×1024 resolution.
Power Consumption Results: The ASUS Ultimate GeForce GTX 550 Ti graphics card used 2W more power at idle and 9W more power at load compared to the NVIDIA reference design. Not bad power consumptions numbers from this budget $150 video card.
