ATX Advanced Technology eXtended is a motherboard configuration specification developed by Intel in to improve on previous de facto standards like the AT design. It was the first major change in desktop computer enclosuremotherboard and power supply design in many years, improving standardization and interchangeability of parts. ATX is the most common motherboard design.
The official ATX specifications were released by Intel in and have been revised numerous times since. The most recent ATX inel specification is version .231. Advantages of having an EATX motherboard is dual socket support. On the back of the computer case, some major changes were made to the AT standard.
Originally AT style cases had only a keyboard connector and expansion slots for add-on card backplates. 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.
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.
Other legacy connectors that are slowly being phased out of modern ATX intdl include pin parallel ports and 9-pin RS serial ports. 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 number of expansion slots.
Standard ATX provides seven slots at 0.
Here width refers to the distance along the external connector edge, while depth is from front to rear.
Note each larger size inherits all previous smaller colors area. 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 intdl.
A number of manufacturers have added one, two or three additional expansion slots at the standard 2.331. 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.
Portable and notebook computers had custom motherboards unique to their particular products. InFoxconn unveiled a Foxconn F1 motherboard prototype, which has the same width as a standard ATX motherboard, but an extended Ztx12v AprilGigabyte announced its The added length could have allowed placement of up to eight expansion slots, but the top slot position is vacant on this particular model.

Although these boards have room for additional expansion slots 9 and 8 total, respectivelyall three provide only seven expansion connectors; the topmost positions are left vacant to provide more room for the Agx12v, chipset and associated cooling.
The new design is dubbed “HPTX” and is Originally, the motherboard was powered by one pin connector. An ATX power supply provides a number of peripheral power connectors and in modern systems two connectors for the motherboard: The inhel pin pitch intrl 4. The 20—pin Molex Mini-Fit Jr. 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.
The general configuration is a double-pole latching mains voltage switch with the four pins connected to wires from a four-core cable. 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. 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. 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.
When 22.31 switch on the power supply is turned off, however, the computer cannot be turned atx12 with the front power button. The power supply’s kntel to the motherboard was changed from the older AT and LPX standards; AT and LPX had two similar connectors that could be accidentally interchanged by forcing the different keyed connectors into place, usually causing short-circuits and irreversible damage to the motherboard the rule of thumb for safe operation was to connect the side-by-side connectors with the black wires together.
ATX uses one large, keyed connector which can not be connected incorrectly.
The new connector also provides a 3. If using an ATX PSU for purposes other inte 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.
A minimum load on one or more voltages may be required varies by model and vendor ; the standard does not specify operation without a 22.31 load and a conforming PSU may shut down, output incorrect voltages, or otherwise malfunction, but will not be hazardous or damaged.
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 intep. It was thought that in this configuration, cooling of the processor would be achievable without the need of an active heatsink.
However, some early model Athlon XP and MP boards including some server boards and later model lower-end motherboards do not have the 4-pin connector as described below.
Numbering of the ATX revisions may be a little confusing: ATX refers to the design, and goes up to version 2. For instance, ATX 2. This is a minor revision from August The power on the 3. A relatively minor ztx12v from January This voltage was required by the ISA bus, which is no longer present on almost all intdl computers.
Introduced in April a month after 2. This standard introduced some changes, mostly minor. Some of them are:. This is a minor revision atx12g June Other minor changes were introduced.

This is a minor revision iintel March The power stx12v slightly increased on all rails. This revision became effective in February This the unofficial name given to the later revisions of the v2. It is specified in Revision 1. SFX is merely a design for a power supply casing, with the power specifications almost identical to ATX. Another small power supply design with standard ATX specification connectors. It was used only on high-end Athlon MP motherboards.
The pinout on the motherboard connector is as follows when viewing the motherboard from above:. This pinout on the motherboard connector is as follows when viewing the motherboard from above:.

It has a pin main connector same as ATX12V v2. 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. High-performance video card power demands dramatically increased during the s and some high-end graphics cards have power demands that exceed AGP or PCIe slot capabilities.
For these cards, supplementary power was delivered through a standard 4-pin peripheral or floppy power connector. The main issues to consider are the following:. Some proprietary brand-name systems require a matching proprietary power supply, but some of them may also support standard and interchangeable power supplies.

Efficiency in power supplies means the extent to which power is not wasted in converting electricity from a household supply to regulated DC. Various initiatives exist to improve the efficiency of computer 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.
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 gains of using an efficient power supply are more substantial in computers that use a lot of power. 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.
