Many power supplies create their 3.
ATX – Wikipedia
For other uses, see ATX disambiguation. ATX power supplies are turned on and off by a signal from the motherboard.
The CE mark is required for power supplies sold in Europe and India. All other voltages are generated by voltage regulator modules on the motherboard. Retrieved from ” https: This protects against system performance degradation, and against power supply overloading.
A power supply that is self-certified by its manufacturer may claim output ratings double or more than what is actually provided. In some cases, in violation of their own advertising eps12b to include it.
Computing portal Electronics portal. This is a minor revision from June Originally at the time of ATX 2. External power supply could send data about itself power, current and voltage ratings to the computer.
Climate Savers Computing Initiative promotes energy saving and reduction of greenhouse gas emissions by encouraging development and use of more efficient power supplies. Climate Savers Computing Initiative promotes energy saving and reduction of greenhouse gas emissions by encouraging development and use of more efficient power supplies.
Modern personal computers universally use switched-mode power supplies. Although a power supply with a larger than needed power rating will have an extra margin of safety against overloading, such a unit is often less efficient and wastes more electricity at lower loads than a more appropriately sized unit.

The manufacturers eps12b these computer system components, especially graphics cards, tend to over-rate their power requirements, to minimize support issues due to too low of a power supply. Most desktop personal computer power supplies are a square metal box, and have a large bundle of wires emerging from one end.
The fan placement can be used to efficiently exhaust air from the processor and core area of the motherboard, making possible smaller, more efficient systems using common industry components. In this case, loading the 3. Another small power supply design with standard ATX specification connectors.

Once the output power is ready to use, the Power Good signal tells the digital circuitry that it can begin to operate. The added length could have allowed placement of up to eight expansion slots, 922 the top slot position is vacant on this particular model. From Wikipedia, the free encyclopedia. Retrieved April 4, The standby power source was a small linear power supply with conventional transformer, which was later changed to a switching power supply, sharing some components of the eps122v unit due to cost- and energy-saving requirements.
The ATX standard followed some manufacturers design [ citation needed ] to have power supplies also supply a standby wpec, so that most of the computer system could be powered off after preparing for hibernation or shutdown, and powered back on by an event. As power supply capacity increased, the ATX power supply standard was amended beginning with version 2.
Power supplies designed for worldwide use were equipped with an input voltage selector switch that allowed the user to configure the unit for use on local power grid. Archived PDF from the original on April 1, Since references to Mini ATX have been removed from ATX specifications since the adoption of microATX, the AOpen definition is the more contemporary term and the one listed above is apparently only of historical significance.
Archived from epps12v original on Several ATX-derived designs have been specified that use the same power supply, mountings and basic back panel arrangement, but set different standards for the size of the board and epd12v of expansion slots. Some power supplies come with sleeved cables, which besides being more aesthetically epa12v, also make wiring easier and have a less 22 effect on airflow.
The original ATX specification called for a power supply to be located spc to the CPU with the power supply fan drawing in cooling air from outside the chassis and directing it onto the processor. Retrieved 18 November Retrieved from ” https: A relatively minor revision from January Wikimedia Commons has media related to ATX.
ATX allowed each motherboard manufacturer to put these ports in a rectangular area on the back of the system with an arrangement they could define themselves, though a number of general patterns depending on what ports the motherboard offers have been followed by most manufacturers.
