NVIDIA GeForce GTX 750 Ti Maxwell GPU Review
Power Consumption and Noise
Before bringing this article to a close, we'd like to cover a few final data points--namely, power consumption, temperatures, 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.

Here is where the GeForce GTX 750 Ti and GTX 750 looks most impressive in our opinion. In terms of frame rates, NVIDIA's latest GeForces trade blows with the Radeon R7 260X and upcoming Radeon R7 265. But there is no contest in terms of power consumption and efficiency. The GeForce GTX 750 Ti and GTX 750 consume similar amounts of power at idle, but under load they consumed significantly less power than similarly performing cards. All of the tuning and tweaking NVIDIA has done to Maxwell has clearly paid off in the performance per watt department.
With power consumption so low, temperatures and noise are non-issues as well. The GeForce GTX 750-series cards we tested typically operated in the mid-50'C range under load and remained virtually silent throughout testing. The cards simply do not get hot. We should note, however, that the dual-fan ACX setup on the EVGA card is louder than the Zotac or reference cooler, though it is still quiet overall.
