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 article is about the computer form factor. The power was slightly increased on all rails.

This voltage was required by the ISA bus, which is no longer present on almost all modern computers. Power supply unit computer. The general configuration is a double-pole latching mains voltage switch with the four pins connected to wires from a four-core cable. 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.

An ATX power supply provides a number of peripheral power connectors and in modern systems two connectors for the motherboard: 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.

Calvert; University of Denver. 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. It was thought that in this configuration, cooling of the processor would be achievable without the need of an active heatsink.

Other minor changes were introduced. The power on the 3. Introduced in April a month after 2. ATX refers to the design, and goes up to version 2. On the back of the computer case, some major changes were made to the AT standard.

Retrieved April 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.

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 CPU, chipset and associated cooling. The 20—pin Molex Mini-Fit Jr. 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. Green computing and 80 Plus.

ATX12V 2.3 vs ATX12V 2.31

This standard introduced some changes, mostly minor. This page was last edited on 7 Decemberat Here width refers to the distance along the external connector edge, while depth is from front to rear.

Wikimedia Commons has media related to ATX. 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. In AprilGigabyte announced its The connector pin pitch is 4.

Archived from the original on September 19, Note each larger size inherits all previous smaller colors area. 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.

This the unofficial name given to the later revisions of the v2. Archived from the original on 24 October 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. 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.

The new connector also provides a 3. Archived PDF from the original on April 1, 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.

ATX – Wikipedia

The gains of using an efficient power supply are more substantial in computers that use a lot of power. This pinout on the motherboard connector is as follows when viewing the motherboard from above:. Retrieved 18 November This is a minor revision from June 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.

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, or otherwise malfunction, but will not be hazardous or damaged. This is a minor revision from March 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.

The new design is dubbed “HPTX” and is
