Below are some of the best motherboards for i5 8400 that will provide you the maximum benefits.

What to look for in the best motherboard for i5 8400?

Choosing the best motherboard for i5 8400It is crucial that you buy the right motherboard not only for the i5 8400 but for any other processor out there. For any PC build, a motherboard can be considered the foundation that holds the entire PC together. It will ensure that all the other components that you have bought for your build go hand in hand and work effectively and collectively to provide you with the best performance possible.

In this article, we list and review some of the best motherboards you can pair with i5 8400, but before we head on to reviewing the best motherboards for the Intel i5 8400 processor let us discuss what you should look for in your motherboard before you purchase one. 

Form Factor – Why is size so important?

Perhaps the single most important aspect of a motherboard is its size or form factor. A larger sized motherboard will have more ports and expansion slots for installing multiple cards and components than smaller motherboards, but all that it boils down to is your personal preference.

Do you want a portable PC? Then you need to opt for a smaller motherboard that can fit in a portable mini ITX case. What if you just want a personal PC to get your office work done at home? In that case, you can go for a standard-sized motherboard for an ATX case that you can keep on your desk.

Nowadays, motherboards come in 3 standard form factors that are commercially available.

  • ATX
  • Micro-ATX
  • Mini-ITX

Socket Type – Go for Connectivity

The rear part of the processor chip consists of an array of pins laid out in a particular order that fits into a motherboard’s socket. A single motherboard is not compatible with all types of processors from different manufacturers of different series. Hence, you must choose a motherboard with a socket that is compatible with the processor you have. There used to be several types of socket types, but in this current generation, there are only two that are used the most- LGA sockets (used by Intel) and PGA sockets (Used by AMD). The Intel i5 8400 processor has an LGA1151 socket and will only fit a motherboard socket compatible with it.

DIMM slots or RAM slots – The More the Merrier

RAM is an essential component for almost everything, whether it be gaming or productivity work. The more RAM you have, the better you will be multitasking with multiple software and programs. It is quite important to look for a motherboard with just the right number of slots to fit your RAM modules. For gamers out there, we recommend a motherboard with at least 4 DIMM slots to ensure that you can install more RAM modules in case you plan to upgrade your PC in the future.

Expansion Slots – Be future Proof!

These slots on the motherboard allow you to install things like Wi-Fi cards, sound cards, and other expansion devices. The standard expansion slot used in motherboards is the PCI express slot, which is found in different sizes. If you are building a PC for gaming that has a full-size PCI-e x16 slot so that you can install a gaming graphics card or GPU to run your graphically demanding games. 

Chipset and Features – Choose what you need

Motherboards are available in different chipsets even if you have the same processor. A motherboard with a newer and updated chipset will offer you more flexibility and the option to overclock your processor.

Some high-end motherboards come with bundled Wi-Fi and Bluetooth features that allow you to use them without installing any cards that save PCI slots. Also, most motherboards come with onboard audio, which is great for most speakers.

Let us now review the motherboards for i5-8400.
