1. how much power does an optimized system with one 1080 ti roughly consume?
2. how much would a whole setup with x4 1080 ti´s consume?
3. how accurate is whattomine with its numbers?
1. Depends on which algo. Equihash will get around 180W per card.
2. Again depending on the algo and TDP setting. Around 900W on the plug.
3. Usually accurate unless sharp network difficulty rise / netowrk delays.

1. Depends on what you are optimizing for- performance and/or power efficiency and algo.
2. Related to #1 but 1000W out the box (factory default of 250W/card), can drop this down or even bump up to 1200W if TDP set for 120% (300W/card).
3. Good ball park reference figure, pretty close and close enough to be fairly accurate. Use as a guide and not a Bible as previous poster mentions to take into account network difficulty spikes and network delays.
