Instructions on how to choose the right motherboard for your computer
The main board (Mainboard, Motherboard) is a very important part in a computer, it is integrated with technologies that determine the features, speed, and stable operation of the whole system. The motherboard will decide which components can run on your computer. All components must be compatible and supported by the motherboard.
There are many motherboard manufacturers with different brands, codes, technologies, types, etc., enough to cause headaches when choosing a motherboard. The following are the basic parameters that you should know when choosing a motherboard.
Form Factor (Mainboard Size)
Picture 1 of Choosing a motherboard for a computer Mainboards come in many different sizes
This is the parameter you should pay attention to first, the size of the Mainboard will determine whether your case will be large or small.
Also, pay attention, the large motherboards will have more features and are equipped with more slots that allow more components to be attached than the smaller motherboards. Currently, the mainboard has the following common sizes:
Mainboard EATX has 1 - 4+ CPU slots, 8 - 16+ RAM slots, 4 - 8 Video Card slots, 6 - 16+ ports to connect to hard drives (SATA). This motherboard is often used for servers, high-end graphics processing computers,.
Mainboard ATX has 1 CPU slot, 4 RAM slots, 2 - 4 video card slots, 6 - 12 ports to connect to hard drives (SATA). This is the common motherboard used for the computers you see every day.
Micro-ATX mainboard has 1 CPU slot, 2 - 4 RAM slots, 1 - 2 Video Card slots, 4 - 8 ports to connect to hard drives (SATA). This motherboard is often used in small computer cases to stand or lie on a desk.
Mini-ATX mainboard has 1 CPU slot, 2 RAM slots, 1 video card slot, 2 -6 ports to connect to hard drives (SATA). This motherboard is often used in microcomputer cases for desktops or in "All in one" machines.
Note that you can still attach a small Mainboard to a larger case, but not vice versa.
