ATX12V vs ATX12V – – An Overclocking Community

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 iintel provide more room for the CPU, chipset and associated cooling. Various initiatives exist to improve the efficiency of computer power supplies. ATX refers to the design, and goes up to version 2. The gains of using an efficient power supply are more substantial in computers that use a lot of power.

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 axt12v safe operation was to connect the side-by-side connectors with the black wires together.

This standard introduced some changes, mostly minor. The wires are either soldered to intfl power button making it difficult to replace the power supply if it failed or blade receptacles were used. It was thought that in this configuration, cooling of the processor would be achievable without the need of an active heatsink.

The pinout on the motherboard connector is as follows when viewing the motherboard from above:. For these cards, supplementary power was delivered through a standard 4-pin peripheral or floppy power connector.


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. Another small power supply design with standard ATX specification connectors. 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.

In AprilGigabyte announced its The most recent ATX motherboard specification is version 2.

ATX12V 2.3 vs ATX12V 2.31

The main issues to consider are the following:. Webarchive template wayback links Articles containing potentially dated statements from All articles containing potentially dated statements All articles with unsourced statements 22.31 with unsourced statements from December Articles with unsourced statements from June Commons category link is on Wikidata.

Archived from the original pdf on This the unofficial name given to the later revisions of the v2. This is a minor revision from June The power on the 3. Views Read Edit View history.

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.

It is specified in Revision 1. Climate Savers Computing Initiative promotes energy saving and reduction of greenhouse gas emissions by encouraging development and use atxx12v more efficient power supplies.

Tax12v 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. 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.

In other projects Wikimedia Commons. The added length could have allowed placement of up to eight expansion slots, but the top slot position is vacant on this particular model. This revision became effective in February This page was last edited on 7 Decemberat The new connector also provides a 3.


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 groundinyel is what the power button agx12v an ATX system does. 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 atz12v slots.

Calvert; University of Denver. This voltage was required by the ISA bus, which is no longer present on almost all modern computers. A minimum load on one or more voltages may be required varies by model and vendor ; the standard does not specify operation without a minimum load and a atx21v PSU may shut down, output incorrect voltages, or otherwise malfunction, but will not be hazardous or damaged.

The official ATX specifications were released by Intel in and have been revised numerous times since. Screw holes not completely compatible with some ATX cases. 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.

Computing portal Electronics portal. Efficiency in power supplies means the extent to which power is not wasted in converting electricity from a household supply to regulated DC. It has a pin main connector same as ATX12V v2. The power was slightly increased on all rails.
