薄型化的更多可能Intel推動主機板新規格ThinMini-ITX

薄型化的更多可能Intel推動主機板新規格ThinMini-ITX在COMPUTEX上，英特尔正式推出了Thin Mini-ITX主板规范，Thin Mini-ITX主板大小保留了Mini-ITX的6.7 x 6.7英寸规格。

但是，如图所示，其I/O挡板将不超过一英寸高（25毫米），而不是普通Mini-ITX主板的一点七三英寸（44毫米）。

标准的Mini - ITX主板（左）Thin Mini-ITX主板（右）英特尔还表示，凭借空间上的节省，这种超薄主板可以更好的应用于超薄个人电脑、推车、医院、自动柜员机等。

而且，Thin Mini-ITX主板尺寸同样适用于目前的Mini-ITX机箱，这也使其在桌面市场中具有了更广泛的空间。

目前英特尔公司没有公布关于Thin Mini-ITX主板的更多细节。

作为第一款英特尔公司的Thin Mini-ITX主板，其型号为D945GSEJT，这款主板采用了英特尔Atom N270处理器与945GSE芯片组。

Thin Mini-ITX主板的主要概括介绍：主板最高支持TDP功耗为65瓦的桌面级CPU显示器接口为LVDS和DP接口（嵌入式DisplayPort）内部显示连接器内存支持SODIMM外部电源供应器（通过背面I/O面板）Mini PCI Express扩展插槽据业内人士介绍，英特尔目前正在与台湾精英电脑系统公司（ECS），神达和微星已经开始商业合作。

而在本周的CeBit展会上神达公司就显示了旗下采用Thin Mini-ITX主板的Maestro 650一体机产品。

如果讀者還有印象的話，距離前一次Intel推行主機板規格，已經是將近十年，2003年推出 BTX（Balanced Technology Extended）的事了。

不過最後因平台建置成本提昇，大幅更改的孔位、零件配置，無法相容前代規格，而不被廠商以及消費市場買單。

其推行路之艱辛與慘澹，最後Intel不得不自行跳出來宣告放棄收場。

Motherboard Mounting Hole Locations (9)3Revision History§ 41Executive SummaryThe Mini-ITX addendum to the microATX Motherboard Interface Specification detailsthe use of the Mini-ITX form factor standard, developed by Via Technologies Inc, forcompatibility with Intel based platforms. This document defines only the specificfeatures in Intel’s Mini-ITX based platforms that differ from those of microATX andshould be used in conjunction with the governing microATX specification.A smaller motherboard layout offers system developers the ability to create new andinnovative system designs. This smaller version of microATX allows and encouragesdevelopers to build within the sub 8 Liter chassis volume for a variety of newapplications.Described within this document are requirements and characteristics of a Mini-ITXmotherboard, so that a motherboard may function and fit appropriately when pairedwith a Mini-ITX chassis. Beyond this, it does not detail processor, memory, graphicsor other system features required to meet the Mini-ITX form factor. These items areleft to system designers and integrators within the guidelines of the microATXspecification.Table 1. Mini-ITX Addendum Feature SummaryThis addendum does NOT define:•Specific power supply form factors•Thermal design guidance to chassis vendors (covered in TASC guide listed in Reference Documents)The Mini-ITX addendum to the microATX Specification is a public document intendedfor widespread application in many types of systems. It is available through a publicwebsite located at:51.1Terminology1.2Reference DocumentsThe following reference documents are posted on the public web site at1.3Benefits to UsersTrends in the industry indicate that users require a smaller and lower cost solution fortheir PC needs. The smaller board size and lower height keep out zones enable areduced sized chassis as it sits on the user’s desk, is mounted on a display, or comesin any other innovative form factor. These changes also enable a PC to be designedinto various aesthetic shapes and sizes.1.4Benefits to ManufacturersBy manufacturing to this Mini-ITX specification, motherboard manufacturers andchassis manufacturers can guarantee a better compatibility between their products.They can also capitalize on the benefits of a reduction in total system costs because ofa reduced system size. This specification allows chassis vendors to design theirproduct targeting the soldered down, low power processors all the way up to highperformance, multi-core processors. It eliminates the need for them to designtargeted chassis for each platform.§62LayoutThis section describes the mechanical specification of the Mini-ITX form-factormotherboard. Size, mounting hole placement, connector placement, and componentheight constraints are specified. System components such as hard drives, disk drives,and power supplies are not specified, however it is generally recommended toconsider what would facilitate assembly, as well as not place components such thatthey block fan inlets. An example layout is depicted in Figure 1.Figure 1. Example Mini-ITX LayoutNote: Depicted system is approximately 8L with standard desktop components.72.1Board dimensionsTable 2. Compares ATX, microATX, and Mini-ITX board dimensions2.2Mounting Hole PlacementMini-ITX utilizes a subset of ATX mounting holes. To avoid damage to traces onmotherboards, chassis standoffs in any locations not specified should be removable ornot implemented at all. See Figure 2 for relative hole location compared to ATX andmicroATX motherboards.Figure 2. ATX, microATX, and Mini-ITX Mounting HolesNOTE:Board is shown oriented with the rear of the board towards the top.NOTE:The lighter portion indicates the approximate region of the Mini-ITX form factor.8Table 3. Motherboard Mounting Hole LocationsFigure 3. Mini-ITX Board Diagram92.3Connector placementAll connector locations as well as allowable placement area for I/O connectors on theback panel are described and can be found in the microATX interface specification. 2.4Height Constraints2.4.1Primary (Component) Side Height ConstraintsOne major advantages of the Mini-ITX form factor is its backward-compatibility withthe ATX specification. The Mini-ITX motherboard can be installed in any ATX chassis.Figure 4 shows the required maximum component height constraints for thecomponents on the PC board. For full compliance with Mini-ITX, and to preventinterference with the chassis structure, power supply, or peripherals, the motherboardcomponents should not exceed the height limit in each zone defined. Similarly,compliant power supplies, peripherals, and chassis features should not extend into themotherboard component area.Figure 4. Mini-ITX Maximum Component Height Restrictions10Notes:•All dimensions in the above figure are in millimeters (mm).•The 57mm height restriction in Area A applies to the PC board componentheight. The actual height of the chassis should include any dynamic excursionconsiderations for shipping as well as needs to facilitate alternative coolingsolutions or airflow considerations.•For Intel boxed processor fan heat sink, it is strongly recommended not toplace components between fan inlet and chassis side vent by leaving spacebetween chassis wall and area A open.•The component height requirement assumes a motherboard thickness of 1.57 mm (0.062”).2.4.2Secondary (Bottom/Solder) Side Height ConstraintsNo height restraints on secondary side are added or removed from what isspecified in the microATX Motherboard Interface Specification.113Power Supply InformationProvided the very different needs of the platforms that fit in the small desktop formcategory, this specification does not attempt to define a standard for the power supplyto match with the Mini-ITX motherboard specification. Instead it recommends thatmanufacturers consider using a:•SFX, TFX or FlexATX are available power supply form factor for chassisgreater than 5 liters•External power adapter for chassis less than 5 litersRefer to the microATX Motherboard interface Specification for information on powersupply requirements.12。

主板分类

电脑主板分几种？按大小分，分为小板（MicroATX)、大板（A TX）、迷你板（Mini ATX）；按是否集成显示芯片分，分为集成显示芯片主板和无集成显示芯片主板；还有一种特殊主板：ITX主板---集成了CPU、显卡的迷你型整合主板。

电脑主板分哪几种型号啊?主板，又叫主机板(mainboard)、系统板(systembourd)和母板(motherboard)；它安装在机箱内，是微机最基本的也是最重要的部件之一。

主板一般为矩形电路板，上面安装了组成计算机的主要电路系统，一般有BIOS芯片、I/O控制芯片、键盘和面板控制开关接口、指示灯插接件、扩充插槽、主板及插卡的直流电源供电接插件等元件。

主板的另一特点，是采用了开放式结构。

主板上大都有6-8个扩展插槽，供PC机外围设备的控制卡(适配器)插接。

通过更换这些插卡，可以对微机的相应子系统进行局部升级，使厂家和用户在配置机型方面有更大的灵活性。

总之，主板在整个微机系统中扮演着举足重新的脚色。

可以说，主板的类型和档次决定着整个微机系统的类型和档次，主板的性能影响着整个微机系统的性能。

常见的PC机主板的分类方式有以下几种★主板的分类：一、按主板上使用的CPU分有：386主板、486主板、奔腾(Pentium，即586)主板、高能奔腾(Pentium Pro，即686)主板。

同一级的CPU往往也还有进一步的划分，如奔腾主板，就有是否支持多能奔腾(P55C，MMX要求主板内建双电压)，是否支持Cyrix 6x86、AMD 5k86 (都是奔腾级的CPU，要求主板有更好的散热性)等区别。

二、按主板上I/O总线的类型分·ISA(Industry Standard Architecture)工业标准体系结构总线.·EISA(Extension Industry Standard Architecture)扩展标准体系结构总线.·MCA(Micro Channel)微通道总线. 此外，为了解决CPU与高速外设之间传输速度慢的"瓶颈"问题，出现了两种局部总线，它们是：·VESA(Video Electronic Standards Association)视频电子标准协会局部总线，简称VL 总线.·PCI(Peripheral Component Interconnect)外围部件互连局部总线，简称PCI总线. 486级的主板多采用VL总线，而奔腾主板多采用PCI总线。

小主板

小巧精致高性能主流ITX小主板推荐2009-5-7 14:40:28 文/Tim,编辑:陈天韵出处：(IT世界网)对于不少的电脑玩家都应该知道mini ITX主板，在VIA大力推动下mini ITX规格在市场上已经存在一段很长的时间，VIA可以说是mini ITX的始祖，此后VIA更推出了规格更小的ITX规格。

市场上的mini ITX主板多数针对工控用户已经一些机顶盒用户，所以在零售市场上比较少见，而且配置一般都比较低，如果想找到比较好的ITX主板只有在二手市场里面寻找。

自从Intel推出ATOM处理器后，Intel将ATOM和945芯片组打包销售，自家推出了ITX规格的ATOM平台，又一次将ITX带到了主流市场，集成CPU的ATOM主板用户只需要配上内存，硬盘和电源就变成一套电脑了，而且功耗要比一般的台式机低很多，虽然性能并不算十分出色，但对于时常需要下载及文件共享的用户是一个相当理想的选择。

而不少的厂商都有推出可以更换CPU或者使用其他CPU的ITX主板，一般都包括现有的Intel的LGA775和AMD的AM2平台的产品。

Mini-ITX是由威盛电子主推的主板规格。

Mini-ITX主板能用于microATX或ATX机箱，尺寸为17 x 17厘米，刚刚好能包括四颗固定螺丝和一条扩充插槽。

由于扩充性不大，Mini-ITX 主要用于嵌入式系统。

英特尔亦有推出使用 Mini-ITX 规格的桌面系统主板，尺寸为171.45mmx 171.45mm，但在网页上标示为“uATX”而非 Mini-ITX。

ITX主板相对于普通的ATX和mATX主板要小巧的多，而且功能也相当齐全。

集成CPU 的ITX主板可以大大降低平台的组建成本，以Intel集成ATOM的ITX主板为例，主板售价499元，加上2G的内存大概150元，电源大概150元左右，对于不同用户对硬盘要求不同如果是下载用户配上1TB的硬盘599元整个平台造价为1398元，远远要比组装一台低价的电脑要便宜很多，而且价格可能要比市面上售卖的1TB的NAS还便宜，功能要比NAS更为强大。

A1876主板解析

A1876主板解析市面上有ATX、MATX、μATX、ITX、XL-ATX、MiniATX、FlexATX、E-ATX、EE-ATX、HPTX及WTX等等一系列的主板版型，说多不多，说少还真不少，就连子凡我这个专业人员来说有时候都有些混乱，所以为了便于记忆，我们可以按照分类及大小为大家梳理了一下这些板型内在的联系，我们一起看看吧。

主板分类：大板：ATX、MiniATX、XL-ATX、非标准E-ATX小板：MATX、μATX、FlexATX迷你板：ITX（包括Thin-ITX）超大板：标准E-ATX、EE-ATX、HPTX、WTX主板尺寸：最小的是ITX主板（170mm*170mm）中不溜的是MATX主板（244mm*244mm）MATX主板宽度砍掉一块，变成μATX主板（244mm*185mm）MATX主板长宽各砍掉一块，变成FlexATX主板（229mm*191mm）大的是ATX主板（305mm*244mm）ATX长宽各砍掉一块，变成MiniATX主板（284mm*208mm）ATX主板加长，变成XL-ATX主板（343mm*262mm）ATX主板加宽，变成E-ATX主板（305mm*330mm）E-ATX主板加长，变成EE-ATX主板（347mm*330mm）EE-ATX主板加宽，变成HPTX主板（345mm*381mm）HPTX主板加宽，变成WTX主板（356mm*425mm）板型的分类尚且如此复杂，更不要体积诸多主板厂商由于种种原因所推出的“形态各异”的“个性产品”。

那么究竟怎样才能把握好主板的板型来选择合适的机箱呢？那就是主板螺丝孔间的孔距。

通过主板孔距示意图我们可以清楚的看到，纵使主板的长宽如何被主板制造商修改，它也必须遵守PC行业的规范——孔距便是其中之一。

一类板型所使用的螺丝孔是固定的，如μATX与MiniATX，它们的主板宽度相似，因此使用两列螺丝孔，只是由于长度的不同，μATX使用两排螺丝孔，而MiniATX使用三排；又如MATX与ATX，因此两种板型均使用三列螺丝，只是由于前者仅仅是在长度上短于后者，所以MATX使用三排螺丝，而ATX使用四排螺丝。

迷你电脑小钢炮你真懂吗

迷你电脑小钢炮你真懂吗作者：超载来源：《电脑爱好者》2021年第03期关于游戏型迷你电脑的搭配，大家可以参考本刊2020年第24期的《与游戏主机试比高小型游戏电脑不简单》一文。

其实，品牌机应当是走出第一步的电脑类产品，不知道大家注意到没有，目前主流的品牌台式机，其实都已经变成基于MATX规格的产品，更有甚者是ITX规格，甚至一些超小的SFF（注：Small Form Factor即超小体积电脑）电脑仅有1升体积（图1）。

而以往传统的ATX规格，大多存在于高端或游戏型产品中了。

可是，这些超小规格的电脑究竟如何搭配选择，如何才能拥有一台超迷你电脑，这还真需要下一番功夫，今天笔者就将这些可能遇到的问题——分享给大家。

迷你电脑最大的特色当然就是对体积的限制性要求较高，这不仅仅考验用户的动手能力，同时也注重对设备搭配选择的经验认知。

当你决定要拥有一台迷你型电脑的时候，第一件事，就是确定它的尺寸。

这其中，机箱无疑成为第一步的选择，因为只有确定了机箱尺寸，你才能知道下一步的规划该如何制订执行。

这其中，选择MicroATX（以下简称MATX）还是ITX就成为了前提条件（图2）。

MATX主板标准于1997年12月由英特尔推出，大小是9.6英寸×9.6英寸，也就是244mm×244mm。

它的长度比标准ATX短20%（ATX标准大小为12英寸×9.6英寸）。

由于长度减少，扩充槽由ATX最多7条减少到4条。

当然，它的安装固定孔位“兼容”ATX规格，所以安装不成问题。

值得注意的事，MATX规格的主板还有一些变种尺寸，例如比较极端特殊的188mm×191mm、170mm×190mm规格，它们看起来非常接近ITX，但是同样属于MATX范畴。

ITX主板标准是由威盛在2001年提出的，它的标准尺寸为170mm×170mm（6.75英寸×6_75英寸），一开始ITX主板只用于不追求性能，集成度极高主板，例如工业设备里的电脑主板等（工控机、广告机等）。
