The power supply connects to an AC outlet and provides power to the components of the computer through a gaggle of DC connectors. AC is connected through a standard CEE three-pronged power cord (see Figure 4.5), which is used with almost all PCs, including Macs, some laptop power supplies, and many other devices, computer-related and otherwise. New cases come with power supplies, but power supplies often wear out and need to be replaced.
