Originally, the motherboard was powered by one pin connector. Archived from the original PDF on October 21, This voltage was required by the ISA bus, which is no longer atx122v on almost all modern computers. 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.

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.
Efficient power supplies also save money by wasting less power; as ijtel result they use less electricity to power the same computer, and they emit less waste heat 2.31 results significant energy savings on central air conditioning in the summer. Although these boards have room for additional expansion slots 9 and 8 total, respectivelyall intdl provide only seven expansion connectors; the topmost positions are left vacant to provide more room for the CPU, chipset and associated cooling.
The new connector also provides a 3. Green computing and 80 Plus.
InFoxconn unveiled a Foxconn F1 motherboard prototype, which has the same width as a standard ATX motherboard, but an extended 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. For instance, ATX 2. It was used only on high-end Athlon MP motherboards.
On the back of the computer case, some major changes were made to the AT standard. 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.

Other legacy connectors that are slowly being phased out of modern ATX motherboards include pin parallel ports and 9-pin RS serial ports. Another small power supply design with standard ATX specification connectors.
ATX12V 2.3 vs ATX12V 2.31
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. Archived from the original on 24 October This revision became effective in February The 20—pin Molex Mini-Fit Jr.
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.
In AprilGigabyte announced its intrl 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. Numbering of the ATX revisions may be a little confusing: Archived from the original PDF on intek 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.

Retrieved 18 Intwl Retrieved February 6, The most recent ATX motherboard specification is version 2. The power supply’s connection 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 qtx12v black wires together.
Screw holes not completely compatible with some ATX cases.
Various initiatives exist to improve the efficiency of computer power supplies. 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.
