[excerpt] In the most basic terms, a power supply converts the high voltage AC power delivered by outlets to lower voltage DC power usable by most devices. It does this with a bridge rectifier and several transformers. However, without a few key modifications power supplies can drastically reduce the quality of the power being supplied to a device.
