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).
Since it's a new unit I dare not to open up the PSU to see what type
of electronics they are using.
So I post the question here ----
Can anyone tell me what type of Power Conversion Electronic Devices
they use in those high PFC rating PSU?
Thank you all !!!
Something like this, perhaps
