Power consumption

Cooling modern video cards is becoming more and more difficult, especially when users are asking for quiet cooling solutions. That's why the engineers are now paying much more attention to power consumption of new video card designs.

To measure power consumption the whole system's mains power draw was measured. This means that these numbers include CPU, Memory, HDD, Video card and PSU inefficiency.

The load value was obtained by running 3DMark03 Nature at 1280x1024, 6xAA, 16xAF. This results in the highest power consumption. While the test was running, power consumption was recorded. The highest reading is listed in the following graph.



With a peak power draw of 200W, the 7900 GTX is quite modest in its power supply requirements. Compared to the ATI X1950 XTX it is definitely more efficient.

Since the Mad Moxx 7900 GTO Burstfire is essentially a 7900 GTX, the 7900 GTX numbers apply to this modded GTO as well.
