The term is most commonly applied to electrical energy supplies. The power supply is a small box inside the computer; it is an important part of a computer because it provides power in a form that is suitable for every other component inside or attached to the computer in order for it to work. If only a small voltage is needed the main supply of power needs to be transformed to a suitable level in order for the component to work. GENERAL DESCRIPTION The complete range of power supplies is very broad, and could be considered to include all forms of energy conversion from one form into another. Conventionally though, the term is usually confined to electrical or mechanical energy supplies. Constraints that commonly affect power supplies are the amount of power they can supply, how long they can supply it for without needing some kind of refueling or recharging, how stable their output Voltage or Current is under varying load conditions, and whether they provide continuous power or pulses. ELECTRICAL POWER SUPPLIES This term covers the mains power distribution system together with any other primary or secondary sources of energy such as:
Power conversion The term "power supply" is sometimes restricted to those devices that ''' ''convert'' some other form of energy into electricity''' (such as solar power and fuel cells and generators). A more accurate term for devices that convert one form of electric power into another form of electric power (such as transformers and linear regulators) is ''' Power Converter '''. Domestic mains adaptors A power supply (or in some cases just a transformer) that is built into the top of a Plug is known as a '''wall wart''', '''power brick''', or just '''power adapter'''.
