Inno3D Geforce GTX580 Review

To test power consumption today we are using a Keithley Integra unit and we measure power consumption from the VGA card inputs, not the system wide drain. The best way to get maximum load results is by using Furmark, and even though it is not indicative of a real world situation it shows the limits the card can theoretically demand. The ‘gaming’ results are measured when playing Crysis Warhead and is a more valuable result to take from this.

This article is also worth a read if you own one of these cards – GPUz can be used to disable power throttling.

Disabling the limiter with GPUz shows that the card can take a maximum of 318Watts when primed in Furmark, when the limiter is in place it peaks around 220watts.
