Knowing About Computer Power Supply (John B. Emmerson III)
Feb 28, 2010
A power supply unit is the parts that provides power to the other parts in a computer. More particularly, a power supply unit is typically created to convert general-purpose alternating current electric power from the mains to working low-voltage DC power for the internal components of the computer.
The most usual computer power supplies are made to conform to the ATX form factor. This enables different power supplies to be interchangeable with various components inside the computer.
ATX power supplies also are built to turn on and off using a signal from the motherboard, and offer support for modern functions such as the standby mode available in most of the computers. The most newest specification of the ATX standard PSU as of mid-2008 is version 2.31.
Computer power supplies are rated based on their maximum output power. Common power ranges are from 300 W to 500 W lower than 300 W for small form factor systems and are intended for regular home computers. Power supplies used by gamers and enthusiasts mostly range from 450 W to 1400 W. Typical gaming PCs feature power supplies in the range of 500-800 W, with higher-end PCs demanding 800-1400 W supplies.
The highest-end units are up to 2 kW strong and are created mainly for servers and, to a lesser degree, extreme function computers with serveral processors, a number of hard disks and multiple graphics cards. The power rating of a PC power supply is not officially certified and is self-claimed by each organization. Power Supply Fundamentals:or How PSU Power Ratings Mean Almost Nothing. A common way to reach the power figure for PC PSUs is by count the power obtainable on each rail, which will not present a real power figure. Therefore it is possible to surplus a PSU on one rail without having to use the highest rated power.
