ATX为何物

Author: 赵恺棣 Date: 1997-01-01

  ATX is the abridgment of ATeXterna.l It is initiated by the Intel Corp.p.to boost the overall performance of motherboard in PC.
  ATX乃ATeXternal的缩.写,是由Intel公司首创以提升微机主板整体性能的新技术。
  What is new about ATX?
  ATX新在何处?
  Comparing with the original Baby/Mini AT motherboard,ATX based motherboard has the following advantages:
  与以前的Baby/MiniAT主板相比,ATX主板有如下优点:
  1.In the Baby/MiniAT based PC,the moth erboard leaves little space for the I/O ports  on board.So it needs extra cables to connect these ports.This will lower the perfor mance of the whole PC. On the contrary,the ATX based motherboard looks like a 90 degree rotation of the Baby AT,this allows the I/O ports(and their connectors)can all be built on board.
  1.Baby/Mini AT的电脑中,主板给板上的输入/输出口留下的空间很小,因此需要附加的线缆来连接这些接口,这就降低了电脑的总体性能。相反, ATX的主板看上去象是旋转了90度的 Baby AT主板,但它却使输入/输出接口及其连接器可直接做在主板上。
  2.The CPU and SIMM slots don't have the best  positions on the Baby/Mini AT board.The CPU fan increases the height of the CPU.And when the fan is damaged accidentally,the CPU will get over hot.Some whole length PCI and ISA cards can't be properly installed because the CPU and its fan are too high on the Baby AT board.And the power supply box often makes the DRAMs hard to insert.But on the ATX based motherboard,the CPU socket and the SIMM sockets are far from the expansion slots,leaving each expansion slot  capable of whole length car.And it is easy to insert or uninsert DRAMs.The CPU is near the power supply box and they share one fan.
  2.Baby/MiniAT主板上原先的CPU和内存插槽位置不合理。CPU顶上的散热小风扇,增加了CPU的高度,且当风扇偶尔损坏时,CPU将过热而由于CPU与其风扇的高度太高使得某些全长的PCI 和ISA卡插不上去,内存也因电源的阻挡而装卸不便。而ATX主板中,CPU和内存插槽均远离扩展槽,所有扩展槽都可以插全长的扩展卡,内存的插拔也很方便。此外,因CPU靠近电源,电源风扇也可给CPU散热。
  3.On the ATX based motherboard,the floppy disk connector and the hard disk connector are just beside the floppy disk support bracket and the hard disk support racket. So shorter cables are needed to connect them.
  3.在ATX主板上,软硬盘连接器正好位于软硬盘支架附近,因此只需较短的连线就可连接它们。
  4.Power supply is advanced on ATX board,making it more energy saving.
  4.ATX主板还对整机的电源做了改进,使其更节省能源。
