I just purchase a Silverstone Power Supply Unit (PSU) for my PC.
I am amaze with the PFC (Power Factor Correction) rating
of over 0.96, which, according to some indicators,
means it's 96% efficient. (4% wastage as heat).
PFC and efficiency are not the same thing.http://en.wikipedia.org/wiki/Power_f...ion_efficiency
