Yet another misleading PUE marketing claim
This "PUE" neatly ignores the missing half of the data centre. These units don't contain the incoming MV or HV transformers that are going to be needed to deliver this sort of power, they don't include the UPS systems that many operators are going to want, they don't include the LV distribution losses or energy costs such as generator preheaters etc.
The claimed PUE is about as accurate as an RIAA estimate of the lost revenue per track shared on Kazaa
