The GeForce GTX 770 Phantom system consumed 325 watts under load, which is only 6 watts more than the GTX 680, pretty good given we received on average 13% more performance. This also meant that the GTX 770 consumed 10% less power than the Radeon HD 7970 GHz Edition while providing 7% more performance.
The GeForce GTX 770 using the Gainward Phantom cooler never exceeded 77 degrees, which is only slightly warmer than the GTX 680 which also happened to be using the Phantom cooler.
