Numbering of the ATX revisions may be a little confusing: The power on the 3. The general configuration is a double-pole latching mains voltage switch with the four pins connected to wires from a four-core cable.

Retrieved February 6, Efficiency in power supplies means the extent to which power is not wasted inetl converting electricity from a household supply to regulated DC.

Proprietary motherboard designs such as those by Compaq, Packard-Bell, Hewlett Packard and others existed, and were not interchangeable with multi-manufacturer boards and cases.

The original ATX specification called for a power supply to be located near to the CPU with the power supply fan drawing in cooling air from outside the chassis and directing it onto the processor. However, some early model Athlon XP and MP boards including some server boards and later model lower-end motherboards do intep have the 4-pin connector as described below. This standard introduced some changes, mostly minor.

It was used only on high-end Athlon MP motherboards. Originally AT style cases had only a keyboard connector and expansion slots for add-on card backplates. It was the first major change in desktop computer enclosuremotherboard and power supply design in many years, improving standardization and interchangeability of xtx12v.


This pinout on the motherboard connector is as follows when viewing the motherboard from above:. Here width refers to the distance along the external connector edge, stx12v depth is from front to rear.

ATX – Wikipedia

The wires are either soldered to the power button making it difficult to replace the power supply if it failed or blade receptacles were used. Archived PDF from the original on April 1, The pinout on the motherboard connector is as follows when viewing the motherboard from above:.

Archived from the original PDF on For other uses, see ATX disambiguation. In addition, many ATX power supplies have an equivalent-function manual switch on the back that also ensures no power is being sent to the components. It was thought that in this configuration, cooling of the processor would be achievable without the need of an active heatsink.

From Wikipedia, the free encyclopedia. An ATX power supply is typically controlled by an electronic switch connected to the power button on the computer case and allows the computer to be turned off by the operating system. Retrieved from ” https: The connector pin pitch is 4.

If using an ATX PSU for purposes other than powering an ATX motherboard, power can be fully turned on it is always partly on to operate “wake-up” devices by shorting the “power-on” pin on the ATX connector pin 16, green wire to a black wire groundwhich is what the power button on an ATX system does. Archived from the original on 24 October Standard ATX provides seven slots at 0.

Note each larger size inherits all previous smaller colors area. Archived from the original pdf on Efficient power supplies also save money by wasting less power; as a result they use less electricity to power the same computer, and they emit less waste heat which results significant energy savings on central air conditioning in the summer. The added length could have allowed placement of up to eight expansion slots, but the top slot position is vacant on this particular model.


Some of them are:. ATX refers to the design, and goes up to version 2. Green computing and 80 Plus.

It is specified inel Revision 1. Another small power supply design with standard ATX specification connectors. The official ATX specifications were released by Intel in and have been revised numerous times since. Any other onboard interfaces such as serial and parallel ports had to be connected via flying leads to connectors which were mounted either on spaces provided by the case or brackets placed in unused expansion slot positions.

Although these boards have room for additional expansion slots 9 and 8 total, inelall three provide only seven expansion connectors; the topmost positions are left vacant to provide more room for the CPU, chipset and associated cooling.

Rather than include the extra cable, many power supply makers implement the 8-pin connector as two combinable 4-pin connectors to ensure backwards compatibility with ATX12V motherboards. Original AT cases flat case style have an integrated power switch that protruded from the power supply and sits flush with a hole in the AT chassis.

InFoxconn unveiled a Foxconn F1 motherboard prototype, which has the same width as a standard ATX motherboard, but an extended This is a minor revision from June Retrieved April 4, Other legacy connectors that are slowly being phased out of modern ATX motherboards include pin parallel ports and intsl RS serial ports.
