Both Titan X and GTX 1080 Ti start off consuming close to 300W at the wall. Then, as the temperature rises and hits the 83°C limit, the frequency and power is scaled back. That is why, after 10 minutes, the systems consume about as much power as a GTX 1080, whose core frequency is undiminished due to better cooling.
The single fan hits about 2,500rpm under full load, and whilst not overly loud, we are of the firm belief that a well-constructed partner card can increase frequencies and lower noise. The reference card looks fantastic but is not the ideal solution for a 250W GPU.
