Nvidia GTX 1080 Ti Founders Edition 11GB Review

We first measure power while the card is sat idling at the Windows 10 desktop for 5 minutes. Gaming power draw is recorded by running Unigine Heaven DX11 benchmark for 5 minutes. As a maximum stress test, Furmark is run for 5 minutes and the cards' power draw levels are recorded.

Unsurprisingly, given the similarities in the GPU used and board TDP, power draw for the GTX 1080 Ti FE is almost identical to that of the Titan X Pascal. The card sips power when idling at the Windows desktop but quickly ramps up to command far more than 200W under load.

Total system power draw from the wall was measured as 332W when running Unigine Heaven benchmark at 1440P. Nvidia recommends a 600W PSU for the GTX 1080 Ti FE and we wouldn't disagree with them when accounting for a CPU load and some headroom.

Compared to the GTX 1080 FE, the GTX 1080 Ti FE commands 27% more power under gaming load. That's a very fair return for a performance improvement that generally sits in the mid-30s percentage range. GTX 1080 Ti FE regularly offers performance increases in the region of 70%+ to GTX 980 Ti and AMD R9 Fury X users. Equally impressive is that it does so while consuming marginally less power (though you'll be unlikely to notice the difference outside of Furmark).
