Total System Power Consumption

Before bringing this article to a close, we'd like to cover a few final data points--namely power consumption and noise. Throughout all of our benchmarking and testing, we monitored how much power our test system was consuming using a power meter. Our goal was to give you all an idea as to how much power each configuration used while idling and while under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not just the power being drawn by the graphics cards alone.

Tested at the Outlet

In terms of power consumption, the new GeForce GTX 570 falls right in-line where you'd expect it to. The GeForce GTX 570 consumed about fewer watts at idle than the GTX 580 and 16 fewer watts while under load.

We also found GPU temps to be similar between the two cards. Idle tems hovered in the mid-to-low 40'C range with load temps in the upper 80s. Noise was not a factor either. While the GTX 570's fan does spin up under load, it is nowhere near as loud as the GTX 480.
