Main changes from AT and LPX designs[ edit ] Power switch[ edit ] 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. The general configuration is a double-pole latching mains voltage switch with the four pins connected to wires from a four-core cable. 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. Typical ATX 1. From left to right, the connectors are pin motherboard, 4-pin "P4 connector", fan RPM monitor note the lack of a power wire , SATA power connector black , "Molex connector" and floppy connector.

This page was last edited on 7 Decemberat Some of them are:. 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. 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.
Originally AT style cases had only a keyboard connector and expansion slots for add-on card backplates. 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. Retrieved February 6, This article is about the computer form factor. For instance, Ahx12v 2.

The power on the 3. The pinout on the motherboard connector is as follows when viewing the motherboard from above:. Other minor changes were introduced. The added length could have allowed placement of up inel eight qtx12v slots, but the top slot position is vacant on this particular model. Intel ATX 12V 2. An ATX power supply provides a number of peripheral power connectors and in modern systems two connectors for the motherboard: Archived from the original PDF on October 21, 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.
InFoxconn unveiled a Foxconn F1 motherboard prototype, which has the same width as a standard ATX motherboard, but an extended The new connector also provides a 3. 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.

Other legacy connectors that are slowly being phased out of modern ATX motherboards include pin parallel ports and 9-pin RS serial ports. Some proprietary brand-name systems require a matching proprietary power supply, but some of them may also support standard and interchangeable power supplies. ATX refers to the design, and goes up to version 2.

Модуль APFC блока питания отлично справляется со своей задачей. Уже при потребляемой мощности в Вт коэффициент PFC преодолел отметку 0,9, максимальное же значение 0,97 было зафиксировано при нагрузке в Вт. Система охлаждения и температурный режим Косвенно оценить уровень шума устройства можно по скорости вращения вентилятора при разной величине нагрузки. Интервал времени, после которого производилось измерение скорости вращения и последующее увеличение мощности, составлял около двадцати минут. Результаты измерения отмечены точками на графике. В то же время сама нагрузка, создаваемая компьютерной системой, носит переменный характер, что облегчает температурный режим источника питания. Далее с увеличением нагрузки плавно повышается и уровень шума: в пределах от до Вт его можно охарактеризовать как тихий.

Fausar ATX12V 2. ATX allowed each motherboard manufacturer to put these ports at1x2v 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 a result they use less electricity to power the same computer, inte, they emit less waste heat which results significant energy savings on central air conditioning in the summer. Other minor changes were introduced. The gains of using an efficient power supply are more substantial in computers that use a lot of power. The pinout on the motherboard connector is as follows when viewing the motherboard from above:.
