In terms of power efficiency, we can report that the Gainward GTX 750 Ti GS can draw a bit more juice (some 10W more) than the reference GTX 750 Ti. This is the result of its high factory overclock that provides 15% better performance, but as you can see from the graph below the whole system draws less than 200W. This means the Golden Sample does rather well. AMD's R7 265 is a little bit faster in games, but GTX 750 Ti GS is much better in terms of power consumption. In idle we measured just over 100W for the whole system. Needless to say these are very impressive figures for a system capable of running most games at 1080p, with plenty of detail to boot.
