ATX standard sizes were developed by VIA Technologies and are de facto ATX standard boards with their own dimensions and layout. The 215×191mm ITX form factor was originally introduced but did not catch on. But Mini-ITX has become widespread as the basis for compact and silent PCs (not the most productive processors allow you to use passive cooling, and the HDD can be replaced with an SSD). Let’s see the different dissimilarities by ATX Vs ITX comparison:
ITX Chassis (Mini Tower):-
Well this would be a differential feature in favor of the ITX board, from the simple fact that it is really helpful for installing a mini computer.
While the ATX board will need a tower that is almost as big as the E-ATX, the ITX will have its own chassis, some chassis since, let’s admit they have slightly poor cooling and little space, but at least its appearance was careful and they can be placed where we want.
ATX (Half Tower or Middle Tower):-
This is probably the most common and preferred type of tower box by users. It supports Mini-ITX, Micro-ATX and ATX motherboards (30cm x 24cm) and has 7-8 expansion slots, depending on the brand. This tower also includes the cable management option, making it a hit with builders who naturally prefer to keep equipment neat and tidy. Although it is not as portable as the first two types of tower, it is the preferred computer case by many gamers, as it can fit into advanced graphics cards and still leave room for other extensions. Its size ranges from 45 to 60 cm.
What’s your Preference?
There are very powerful game boards in this format and also with Wi-Fi and support multiple GPUs. If you find a good opportunity in the market, it is as valid as the ATX, but the truth is that it is not as mobile as the ITX and not as wide as the ATX.
How To Measure Best Fit?
There is also an ITX format, which differs from ATX in a slightly different arrangement of external connectors and smaller size. Which motherboard to choose (ITX or ATX) – depends on the case. When upgrading Media Center, it is advisable to arm yourself with the ruler and measure the values by comparing them with the parameters of the same, so as not to miscalculate.
Almost all modern motherboards are equipped with a full-length PCI-E x16 slot for installing a video card. Only ultra-compact ITX boards may lack this, as they are designed to use CPUs with integrated graphics (for example, the Intel Atom or AMD A-series).
If in the future it is planned to make the configuration of two video cards, then there should also be 2 compatible slots. In this case, the MP3 chipset requires hardware support for SLI or CrossFire technology (depending on the manufacturer of the graphics card).
Mini-ITX is the worst option available because there is very little space in the case. Of course, you can build a gaming PC with a Mini-ITX board, but you must carefully consider the place for the video card and cooling. There isn’t much room in a Mini-ITX case, especially when compared to ATX.
