ASUS GeForce GTX 780 Ti DirectCU II Review
Power Consumption, Noise, and Stability
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 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.
ASUS's DirectCU II solution consumed around the same amount of power as the cards from Gigabyte and EVGA. It's recommended that you own a quality 600W power supply for a card like this, or higher if you want to give yourself some headroom to play with (for overclocking and/or future overclocking).
Noise and StabilityThe DirectCU II solution from ASUS is another example of a cool running and quiet option. Even at full load, this card doesn't approach anything that we'd consider loud, and in most instances, you're not going to hear it running unless you slap your face against your case.
We didn't run into any stability issues with ASUS's card. That's not something to take for granted -- the aggressively clocked card from Gigabyte show a few minor instances of instability throughout our previous roundup. We put the ASUS card through the same paces without issue.
