MINI ITX motherboard

MINI ITX motherboard

Every gamer or PC enthusiast understands the significance of a motherboard, but not everyone is aware of the features offered by individual form factors. Before purchasing one, you should understand its basic differences and features.

A motherboard can only be differentiated based on supported socket type. Intel processors work only with LGA11 sockets or socket H4, while the AMD processors work with AM4 sockets. 

Hence before purchasing one, it is most important to decide the processor you wish to install on the motherboard. The latest 11th generation intel processors work only with the LGA 1200 sockets.

While purchasing a processor, it is not mandatory to go with the latest ones, they are always expensive.

Instead to prolong its life, one should invest a little more in buying a motherboard that supports higher generation processors. Click here to learn about the difference between different form factors cases.

MINI ITX motherboards have limited PCIe, RAM slots, forcing you to settle for less and make do with the limited possibility of a hardware upgrade.

These are great for a compact PC and official working desk that requires less gaming and more computational performance.

However, a lot of MINI ATX motherboards can be merged with a liquid cooling system and top-of-the-line graphics card without an issue.
