The motherboard is the piece that holds it all together and you wouldn’t have your computer without it. The only way other major components of your components can communicate is through the motherboard, though previously only important parts of the PC were connected to it, nowadays almost everything is. Distributing power through the circuits to every inch of the PC is also something that your motherboard is responsible for. If you had a picture, your motherboard would be the frame that keeps it together. These motherboards come in a variety of shapes and sizes and make up different layouts, though some international standards are in place.
Choosing the right motherboard you need for your system isn’t too hard, there’s plenty of information about all sorts of different types that you can learn about online. What defines the dimensions and such of a motherboard is its form factor. The number of ports on the motherboard and location of its slots are all defined by it. Putting together pieces on a motherboard might look intimidating, especially for a first-timer when building your own PC, but if you have had practice putting puzzle pieces into their corresponding slots which are similarly shaped, you shouldn’t have too much problem with a motherboard.
Defining which form factor you need to implement for your rig takes into full view what you plan to use it for. Many gamers weigh their options between atx vs itx motherboards since one major requirement for them is going to be the power consumption rate. A mini itx motherboard is smaller than a lot of motherboards and also makes the least noise and offers a lot of RAM for what it does. In the end, it’s combination of price, size and performance that will decide your choice for you.
