Power Consumption Testing
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 just the power being drawn by the graphics cards alone.
The GeForce GTX 950 cards from ASUS and EVGA we tested, were quite power friendly. Both of the cards consumed the same about of power at idle, though the EVGA card used somewhat more under load. Both cards, however, consumed the least amount of power of the bunch.
With such low power consumption, it should come as no surprise that these GeForce GTX 950 cards are relatively quiet as well. Both cards are basically inaudible at idle over a typical CPU cooler and PSU fan, especially since their fans can spin down at lower-temps and not product any noise at all. Under load, their fans do spin up somewhat, but both cards remained quiet throughout testing.
