Are you having an intel i5 8400 processor and want to build a system with it, but don't know which motherboard will be the best? Or simply, you are looking for the best motherboard for the i5 8400 processor. Then don't worry, I have got your back here.

As we all know, the motherboard is the most critical part of a device, otherwise known as Mobo or Mainboard or System board, as it connects other hardware, making your system run entirely. That means choosing the right best motherboard for i5 8400 is critical.


As already I described here, we will discuss the best motherboard for intel i5 8400, which is a locked CPU and thus handle everything very smoothly. Before going to the list, lets take a look at the features you must look for in the motherboard you are going to purchase.

Things to Remember before buying Motherboard for i5 8400

Well, you must know the necessities before choosing the right Motherboard for your perfect built-in. Here I have given some tips to follow before picking the best Motherboard for i5 8400.

CPU Support

As you take intel i5-8400 as your ideal processor, you should also know some other things before choosing the perfect CPU for your system. There are generally two things, they are the socket of CPU that fits in your mobo and a chipset.

Choose the perfect socket and chipset that is compatible with motherboards for i5-8400. The system board Z370 chipset support i5-8400, but it is a little bit pricey, and it's profitable to buy mobo Z370 if you have an overclocking CPU, which you can't do with i5-8400. Thus, it is not worth buying such a motherboard.


There are three significant sizes of motherboards found in the market, and all of these are well-matched with our ideal CPU. These three are ATX, MicroATX, and MiniATX. Besides the size, you should see the number of ports and slots present in that mobo.

Ports and Slots

Generally, larger sized system boards contain large number of ports and slots. But still, you must see whether the PC cases are matching or not.

Mostly, significant PC cases are well-suited with smaller motherboards. So, it does not make sense to buy an outstanding mobo for more ports and slots. Make sure the main board you choose has all the ports like USB ports and audio ports and slots.

RAM Compatibility

If you are transforming your processor and motherboard, you should also upgrade your RAM. Because i5-8400 CPU is only friendly with DDR4 RAM, so make sure you have that one.

Now that you have learned about the different specifications to be kept in mind before buying the best Motherboard for i5 8400, let's move onto the list without wasting time.
