Each of those sets of racks is, what, 500 GPUs? And there are 12 racks so 6000 altogether. And they’re presumably being run flat out 24/7. Nvidia recommend a 700w psu, so let’s say they’re pulling 500 watts each for ease of maths. Even if we ignore all the other kit required (e.g control, aircon etc) that means that room is pulling absolute minimum 3 megawatts of power. That is the same as about 1000 average U.K. homes. Put together.
