The use of cigarette lighter receptacles to supply 12 volt DC power is an example of backward compatibility to a de facto standard. As a power connector, the lighter receptacle is larger, harder to use and less reliable than other DC connectors [citation needed]. Cigarette lighter receptacles are in widespread use in many highway vehicles and ...

This is a critical point – each power supply must be able to power the entire server by itself. Redundancy is further enhanced by plugging each power supply into a different circuit (i.e. to a different circuit breaker).

For a 75% efficient power supply to produce 75 W of DC output it would require 100 W of AC input and dissipate the remaining 25 W in heat. Higher-quality power supplies can be over 80% efficient; as a result, energy-efficient PSUs waste less energy in heat and require less airflow to cool, resulting in quieter operation.
