Processors and GPUs get more attention when it comes to building your system, but motherboards are also a very integral part of a PC. Motherboards are the central circuit hub of a PC; every part of your PC connects to it. It regulates the power supply, which provides your CPU, GPU, hard drive, and system memory with power.

The form factor of your motherboard will decide your computer size, and the chipset and socket will dictate what kind of CPU you can use. It will not be an overstatement to say that motherboards are the backbone of your computer system.
The Core i5-8400 Chipset
In the old days, various PC components had to go through several chips in different places on the motherboard to talk to the CPU. This set of chips were called a chipset. Later, with the development of computer systems, these sets of chips were integrated into a single chip for efficiency.
Many things that were first handled by the set of chips like memory and graphic controllers, are now integrated into and controlled by the CPU. The chipset handles the remaining duties. This way, latency is decreased, and consequently, the system is more responsive.
The chipset and processor work together to make the computer function. Your chipset dictates a few things for you. The buses used in chipset let you determine how much room you have for expansion cards. It also determines overlocking potential. You can overclock some chipsets, while there are some that you can’t.
The i5-8400 is compatible with several Intel chipsets: B360, H370, H310, Q370, and Z370. Although all the functions and features of these chipsets, especially the Z370, are similar to the previous generation Z270, there is an updated microcode that only recognizes this processor.
Requirements of the i5-8400 CPU
Core i5-8400 is a reasonably priced hexa-core processor from Intel’s 8th generation Coffee Lake range. The processor’s base clock speed is 2.8 GHz, while its max turbo frequency is an impressive 4 GHz. Before buying the i5-8400, you need to keep a few things in mind.
This Coffee Lake processor needs a new motherboard and a 300-series chipset. This is due to the modified power needs of this processor. The pins-out on this processor are different from its other range of processors like the Kaby Lake.
Why You Should Get the Most Compatible Motherboard for the Intel i5-8400 Chipset
Motherboard selection is an important decision one has to make when building their computer. The motherboard should have enough ability to run all the fans and to keep the processor cool.
