Power consumption for the EVGA GTX 980 Ti SC+ ACX 2.0+ is slightly higher (10W to 20W) compared to the reference GTX 980 Ti. Higher power consumption is due to high factory GPU overclock, but for that you get better performance. Overall, performance-per-watt is good. Recent Geforce cards tend to consume 10 to 40 watts less than competing Radeon cards in a multi-monitor scenario. The whole testrig using EVGA GTX 980 Ti SC consumed below 500W during game tests.
