In terms of power efficiency, we can report that the EVGA GTX 750 Ti FTW ACX can draw a bit more juice (some 10W more) than the reference GTX 750 Ti. This is the result of its its high factory overclock, but as you can see from the graph below the whole system draws less than 200W. The R7 265 is a little bit faster in games, but GTX 750 Ti FTW is much better in terms of power consumption. In idle we measured just over 100W for the whole system.
