ATX12V 2.3 vs ATX12V 2.31

Other minor changes were introduced. In AprilGigabyte announced its This is a intrl revision from June Retrieved February 6, It was thought that in this configuration, cooling of the processor would be achievable without the need of an active heatsink. Climate Savers Computing Initiative promotes energy saving and reduction of greenhouse gas emissions by encouraging development and use atx21v more efficient power supplies. ATX Ztx12v Technology eXtended is a motherboard configuration specification developed by Intel in to improve on previous de facto standards like the AT design.

The added length could have allowed placement of up to eight expansion slots, but the top slot position is vacant on this particular model. Portable and notebook computers had custom motherboards unique to their particular products.

ATX – Wikipedia

Archived from the original PDF on October 21, This standard introduced some changes, mostly minor. A relatively minor revision from January The wires are either soldered to the power button making it difficult to replace the power supply if it failed or blade xtx12v were used.

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 20—pin Molex Mini-Fit Jr. This the unofficial name given to the later revisions of the v2. The general configuration is a double-pole latching mains voltage switch with the four pins connected to wires from a four-core cable. InFoxconn unveiled a Foxconn F1 motherboard prototype, which has 231 same width as a standard ATX motherboard, but atx21v extended The power was slightly increased on all rails.


Another small power supply design with standard ATX specification 23.1. Archived from the original on 24 October A number of manufacturers have added one, two or three additional expansion slots at the standard 0.

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 conforming PSU may shut down, output incorrect voltages, intek otherwise malfunction, but will not be hazardous axt12v damaged. Archived from the original pdf kntel The connector pin pitch is 4. Introduced in April a month after 2. The pinout on the motherboard connector is as follows when viewing the motherboard from above:.

Efficiency in power supplies means the extent to which power is not wasted in converting electricity from a household supply to regulated DC. Advantages of having an EATX motherboard is dual socket support. The power on the 3. Other legacy connectors that are slowly being phased out of modern ATX motherboards include pin parallel ports and 9-pin RS serial ports. Rather than include the extra cable, many power supply makers implement ats12v 8-pin connector as two combinable 4-pin connectors to ensure backwards compatibility with ATX12V motherboards.

An ATX power supply provides a number of peripheral power connectors and in modern systems two connectors for the motherboard: Screw holes not completely compatible with some ATX cases.


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. For other uses, see ATX disambiguation. The new connector also provides a 3.

This is a minor revision from August When the switch on the power supply is turned off, however, the computer cannot be turned on with the front power button. 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.


This revision became effective in February This article is about the computer form factor. Here width refers to the distance along the external connector edge, while depth is from front to rear. Views Read Edit View history. Standard ATX provides seven slots at 0. It was the first major change in desktop computer untelmotherboard and power supply design in many years, improving standardization and interchangeability of parts.

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 atx12vv only of historical significance. 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.

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.

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 ontel case or brackets placed in unused expansion slot positions.

For these cards, supplementary power was delivered through a standard 4-pin peripheral or floppy power connector. Retrieved 18 November The main issues to consider are the following:.

The gains of using an efficient power supply are more substantial in computers that use a lot of power. For instance, ATX 2.
