itx、m-atx、atx、e-atx 机箱的区别主要是尺寸大小和扩展性能的不同，它们的外形大小恰好是按照这个顺序递增的，也就是从小到大排列。 一般来说，itx机箱是最小的，就是常说的超小型机箱，适合组建超mini电脑。

2023年8月25日 · EATX (or E-ATX) vs. ATX Motherboards: What’s The Difference? The primary difference between an ATX motherboard and an Extended ATX motherboard is that the Extended ATX motherboard is going to be wider than an ATX motherboard. That’s the simplest and quickest way to explain the difference, and unfortunately, it doesn’t get much simpler from here.

2024年3月15日 · Both ATX and EATX are the standards for sizing motherboards. Intel released ATX motherboard in 1995 and then the EATX motherboard was released as a bigger version of the ATX motherboard. This post introduces ATX vs EATX motherboard from 3 aspects: size, functionality, and price.

在购买或组装 pc 时，您最有可能遇到四种流行的外形尺寸之一：e-atx、atx、micro atx 和 mini itx。 首先，我们从“标准 atx”主板开始。 atx 代表“先进技术扩展”，早在 1995 年就已开发出来。如果您拥有或曾经拥有一台普通尺寸的 pc，那么它很可能拥有 atx 主板。

2024年9月10日 · Advanced Technology eXtended or ATX is a motherboard that was introduced in 1995 by Intel to improve the standardization of motherboards. ATX motherboards are available in different sizes and have slightly different functionality. They are Micro-ATX, Mini-ATX, WATX, EATX, mobile ATX, and pico-ATX.

2023年12月24日 · From ATX, motherboards get either bigger or smaller in size. Going bigger, you have the E-ATX motherboard (Extended ATX), which adds more area and components to the ATX board and is slightly larger as a result. Going the other way, you have the Micro ATX (mATX), which is smaller than ATX.

先说结论：itx、m-atx、atx、e-atx 说的不是机箱，而是主板的规格。 所以主打某个规格主板的机箱，就是对应的机箱，而且机箱可以向小兼容。 因此，一方面，ITX机箱可以比MATX机箱、ATX机箱小，但不是100%绝对。

eatx是一种加强型atx结构，它是在atx基础上横向加宽主板，以获得比atx更充裕的pcb空间，多出的这部分pcb可以放置各种元器件和接口，比如微星的龙魂动态面板，有些则可以放m.2等。

2024年6月2日 · 目前市场主流的主板板型主要包括atx（标准型）、m-atx（紧凑型）、mini-itx（迷你型）和e-atx（加强型）四种。 ATX主板，是标准的大型主板，形状为长方形，标准尺寸约为30.5cm×24.4cm。

6 天之前 · ATX motherboards come with around six PCI slots (usually 3x PCI-E x16 and 3x PCI-E x1, but this can vary between models), while Micro ATX comes with around three (1x PCI-E x16 and 2x PCI-E x1). This means less space for modifications …
