PFC: How does it work

PFC is something I have seen on a computer ATX and I have wondered about how it works and what is the purpose of it.

The purpose is to make the device more efficient.
Google is your friend for an in depth explanation.

Power factor correction (PFC) in ATX power supplies adjusts the phase between voltage and current, boosting efficiency and reducing stress on the power grid.
