ATX power supply

A PC power supply is used for transferring power to all the parts within a computer. It functions by converting alternating electrical current (AC) into a usable form of low-voltage DC power, which is compatible with the delicate structures within a computer. The majority of computer power supplies are developed to fit the (Advanced Technology Extended) ATX standard. This means that most types of PC power supplies can be utilized with various types of internal components.

The ATX form factor was developed in 1995 by Intel. It was one of the greatest modifications to the power supply unit, the casing and motherboard in a long time. It replaced AT as the leading standard in computer power supply design. It was created with the objective of nullifying most of the issues system builders had with AT power supply units. A more current system has since then been created to replace ATX known as the BTX standard which was introduced in 2003. Most pre-fabricated systems are now using the BTX standard, however, the ATX is still available and still largely used in systems that are built manually. The ATX model has been revised many times since it was initially put on the market in 1995 the latest version is 2.3 which was released in 2007. The dimensions of the ATX board are approximately 12 in x 9.6 in or 305 mm x 244mm which makes it compatible with microATX boards.

A conventional PC power supply will be a square shaped metallic box with a set of bundle wires coming out of one end. These wires are utilized to enable connection to various points within the computer's internal structures. Each component will be linked to the main power supply allowing each to work effectively. The bundle of wires will be parallel to the air vent and C14 IEC connector, which will be used for supplying the computer with AC power from the external power source. On some of the more sophisticated models a power switch is included, which can alter the volts utilized in the process of powering up the PC. A label will also be visible which will indicate very vital technical information that is linked to the power supply this will include the maximum power output and safety certifications. There are various certification standards including: UL mark, GS mark, TUV, NEMKO, SEMKO, DEMKO, FIMKO, CCC, CSA, VDE, GOST R BSMI and CE mark. A number of countries will have divergent standards that a manufacturer will be required to conform to, for example in India and Europe all power supplies must have the CE mark to be legally sold on the proper market channels.

All computers need a power supply to work. You can improve the longevity of your ATX power supply by using a surge protector to protect it from periodic fluctuations in electrical output that may manifest. Additionally you may also want to consider shutting down the computer completely during very bad lightening storms, which may damage the power supply especially if it is not presently on a surge protector.Please visit these link for an interesting article on ATX power supply. and this link for more information on ATX Power Connector.
