ATX Power Supply



What is  ATX (Advanced Technology eXtended) Power Supply.?

ATX (Advanced Technology Extended) power supply is reduced size of the power supply in new generation. It is developed by Intel in 1995 to improve on previous standards like the AT form factor in a motherboard form factor specification. That was the first large change in computer case, power supply, and motherboard. That was designed in many years and finally it will change the mechanical dimensions, I/O panel, power of connectors and connector interfaces between motherboard and power supply. That was the lower cost power supply and ATX overtook AT completely default form factor for new computer systems within a few years. After that Other standards also coming for smaller boards (microATX, FlexATX and mini-ITX) are some of them. Intel introduced the BTX standard as a replacement for ATX in 2009 but ATX form factor remains a standard and BTX has used in pre-made systems. That was designed to solve the problems in LPX and BAT Motherboards.
