I mean that’s just the theoretical power from adding up all of the PSU ratings. Actual power is less, since it’s just the video cards working, optimized for hashes per watt (i.e. not maximum power), and most of the time it would be two or one computer running, since the others would be away from their desk or playing games or doing something important
