We first measure system-wide power draw from the wall while the card is sat idling at the Windows 10 desktop for 5 minutes. Gaming power draw is recorded by running the Deus Ex benchmark at 4K. As a maximum stress test, Fire Strike Ultra Stress Test is run 5 consecutive times and the cards’ power draws are recorded.
Perhaps not surprisingly, the Zotac AMP Extreme 1070 Ti draws a fair bit of power – after all, the applied overclocking settings did set the power target to 140%, the maximum value. In the above chart, you can see the card was actually drawing similar amounts of power to a GTX 1080 Ti.
