Asus GeForce Matrix GTX 580 Platinum 1536MB Graphics Card Review

To test power consumption, we monitor the overall power of the system through a plug-in electricity usage monitor at an idle and load state. This allows us to show the fluctuation between how much power draw the graphics card takes at idle and at load. By monitoring the overall usage of the whole system, it gives an easy comparison if you wish to do the same yourself as opposed to buying very expensive individual testing equipment.

Quite a surprise here with only 103 Watts being used at idle, whilst a whopping 359 Watts were used at load but no decent power supply should have a problem with these types of figures and outputs.
