GeForce GTX 980 Ti Round-Up With MSI, ASUS, And EVGA
Power Consumption, Noise, and Temps
Before bringing this article to a close, we'd like to cover a couple of final data points -- namely, power consumption and noise. Throughout all of our benchmarking and testing, we monitored acoustics and tracked how much power our test system was consuming using a power meter. Our goal was to give you an idea of how much power each configuration used while idling and also while under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not the power being drawn by the graphics cards alone.
There's very little to talk about in terms of power and temperatures. All of the cards consumed similar amounts of power at idle. And while under load only 20 watts separates the EVGA card and the ASUS card. GPU temperatures on all three cards peaked at either 74 or 75 degrees as well, when we weren't overclocking.
In terms of its noise output, the cards were all very quiet as well. At idle, their fans don't even spin, so the noise output from the system was generated by the CPU cooler and PSU. Under load, all of the GeForce GTX 980 Ti card remained relatively quiet as well, though the EVGA card's fans produced slightly more noise than MSI's or ASUS'. Our particular ASUS STRIX sample also generated a slight bit of inductor whine under load, but we're told this is not indicative of all STRIX cards.
