What is a power specification

The ATX Power specification is the motherboard and power structure standard established by Intel Corporation in 1995, and the ATX is an abbreviation for English (at Extend). ATX Power specifications have experienced phases such as ATX 1.1, ATX 2.0, ATX 2.01, ATX 2.02, ATX 2.03, and ATX 12V series.

Starting with the P4, the power specification began using the ATX 12V 1.0 version, and the main difference from ATX 2.03 was to use the +12v voltage to power the CPU instead of the previous +5v voltage. This strengthens the +12v output voltage, and will obtain a much higher load than the +5v voltage to solve the P4 processor's high power consumption problem. Intel released the new ATX 12V 1.3 specification in April 2003. The new specification, in addition to strengthening the power supply +12v output capacity, in order to ensure the safety of the output line, to avoid loss, deliberately formulated a single channel +12v output must not be greater than 240VA limit. The new specification also provides a dedicated power supply interface for the Up-and-coming SATA hard drives.

Intel launched the Power ATX 12V 2.0 specification with the advent of Pci-express in 2005, driving the demand for power to the video card. This time, Intel chooses to increase the second +12v output to address the power supply problems of large power devices. The ATX 12V 2.0 specification also increases the power supply full load conversion efficiency standard to more than 80%, further achieves the environmental protection Energy saving request, and strengthens the +12v the current output ability again. After the ATX 12V 2.0 specification has been developed, Intel has made minor modifications to ATX 12V 2.01, ATX 12V 2.03, and so on, and has largely increased the +5VSB current output requirements. Since May 2006, Intel has introduced the ATX 12V 2.2 specification, in contrast, the new version has not changed much, mainly to further improve the maximum power supply. April 3, 2007, Intel released the latest ATX12V 2.3 standard, "quiet" the year-long power specification is upgraded again. Intel released the 2.3 standard, mainly for Vista system hardware upgrades and dual-core, multi-core processor power changes. ATX12V Version 2.3 specification is more fit for today's mainstream needs, and with the past power specifications have a larger difference, and the atx12v 2.31 version of the specification is more fitting today's mainstream applications, and in the efficiency, environmental protection and energy-saving design is also more perfect. So we have reason to believe that atx12v version 2.31 Power will enter the mainstream market, and eventually spread. Unless the main components of the power consumption change.
