We measure the amount of power drawn from the wall by the entire test system. Our Core i7-5960X CPU is heavily overclocked and has a large bearing on the power draw readings when it is heavily loaded in GTA V. The important information is the difference in power draw levels between each card.
Power consumption of the Palit card is decent, although the electronics system does not seem to be quite as efficient as that used by Asus (albeit very marginally). The card drops its core voltage when Furmark is applied in order to protect the hardware.
