ASUS ROG STRIX GTX 1080 Gaming A8G 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.

Power consumption numbers for the ASUS ROG STRIX GTX 1080 A8G are positive. For its small performance improvement over the GTX 1080 FE, the STRIX A8G requires an additional 10-20W of power under a gaming load. The STRIX A8G is also about 10W less power-hungry than Gigabyte's marginally higher-clocked G1 Gaming GTX 1080.

You could probably get away with powering an overclocked Core i7-6700K and ASUS ROG STRIX GTX 1080 A8G gaming system using a good quality 450W PSU (not that we'd necessarily recommend it). That really is a testament to the power efficiency of Nvidia's Pascal GPU architecture.
