Inte, 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. On the back of the computer case, some major changes were made to the AT standard.

ATX12V 2.3 vs ATX12V 2.31

Climate Savers Computing Initiative promotes energy saving and reduction of greenhouse gas emissions by encouraging development and use of more efficient power supplies.

When the switch on the power supply is turned off, however, the computer cannot be turned on with the front power button. Retrieved April 4, Green computing and 80 Plus.

It was used only on high-end Athlon MP motherboards. 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.


The general configuration is a double-pole latching mains voltage switch with the four pins connected to wires from a four-core cable. The connector pin pitch is 4. The added length could have allowed placement of up to eight expansion slots, but the top slot position is vacant on this particular model. Retrieved February 6, Advantages of having an EATX motherboard is dual socket support.

A minimum load on inetl or more voltages may be required varies by model and vendor ; the standard does not specify operation without a minimum load and a conforming PSU may shut down, output incorrect voltages, or otherwise malfunction, but will not be hazardous or damaged. For instance, ATX 2.

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 22.31 below. The 20—pin Molex Mini-Fit Jr. 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.

This is a minor revision from March This the unofficial name given to the later revisions of the v2. Here width refers to the distance along the external connector edge, while depth is from front to rear. A relatively minor revision from January This pinout on the motherboard connector is as follows when viewing the motherboard from above:. The power on the 3. It is specified in Revision 1.


This voltage was required by the ISA bus, which is no longer present on almost all modern computers. 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 the black wires together.

This is a minor revision from August From Wikipedia, the free encyclopedia.

It was the first major change in desktop computer enclosuremotherboard and power supply design in many years, improving standardization and interchangeability of atc12v. 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.

The main issues to consider are the following:. Standard ATX provides seven slots at 0. Other minor changes were introduced. Numbering of the ATX revisions may be a little confusing: The new connector also provides a 3.

It was thought that in this configuration, cooling of the processor would be achievable without the need of an active heatsink. The new design is dubbed “HPTX” and is
