My experience - consumption:

3x S3 (218,75MHz) - PSU Corsair RM1000 230V 1000W (12V/83A) - on the wall 1020-1035W, so if efficiency 88%, it means on DC side only 905W (+/-)

2x S3 (218,75MHz) - PSU FSP AURUM PRO 850 230V 850W (12V/70A) - on the wall 670-676W
2x S3 (237,5MHz) - PSU FSP AURUM PRO 850 230V 850W (12V/70A) - on the wall 740-745W

similar to mine on different PSU too

similar to mine 2 at 231.25 + 1 at 237.50 total watts 1110 on an evga 1300 that is about 370 watts each or more likely 365 + 365 + 380 = 1110

I'm curious as to what the ambient room temperatures were when these measurements were recorded. According to my data, at-the-wall wattage goes up by approximately 1W per 1C rise in ambient room temperature. Right this very moment is the hottest ambient room temperature that my units have had to endure:

Tambient = 38.7C (101.7F)
Tdevice = 49C
Frequency = 243.75M
Speed = 490.xx GH/s
At-the-wall wattage = 425W

Edit: Tambient is now at 39.4C (103F) and most likely still rising
