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.
Not surprisingly, both GTX 1070 Tis draw more power than a 1070 and less than a 1080. Of the two, the MSI card is marginally less power hungry – though that is perhaps to be expected given its performance was always slightly behind that of the Palit.
