Best Motherboard For I5 8600 – Buyers Guide

The Intel Core i5-8600K processor is quite competent and only compatible with some motherboards. You should consider the following features when purchasing the board to avoid limitations or incompatibility issues.

CPU sockets

Since you already know which CPU you are using, your work here is pretty straightforward. The CPU you plan to use with your motherboard will narrow down your options. In this case, it will use the 8th generation Intel Core i5 processor. This means that you should only focus on boards with LGA 1151 sockets.

Intel tends to change socket compatibility with each processor version, so choosing a motherboard that is compatible with the i5 8600K can be confusing. Luckily for you, all the motherboards described in this guide are compatible with this processor, so all you have to do is choose one that fits your budget and preferences.


Motherboard sizes, sometimes known as form factors, fall into three common types. These are:

  • ATX – The most common type of form factor with enough space for different types of plugs and slots.
  • Micro-ATX – A little shorter than ATX boards, which means it offers less space for expansion slots.
  • Mini-ITX – The smallest in size. It typically offers limited space for some RAM and storage connectors and a single add-in card such as a video card.

The i5 8600K is primarily compatible with ATX boards, which is why most of our recommendations come in this form factor.


When buying a motherboard for i5 8600K, make sure it supports all the peripheral connection options you will need. The more ports they support, the better. This will allow you to include additional ports through the PC front panel connection or by using inexpensive expansion slot brackets on the back of the PC.

The most important ports to consider include USB 3 / USB 3.1 Gen1, USB 2, USB 3.1 Gen2, USB Type-C, HDMI, Thunderbolt 3, audio ports, and PS / 2 ports.

You are unlikely to find Thunderbolt 3 ports on motherboards. There are some accompanying models.

If you find one, you are in luck as they provide impressive connections of up to 40 Gbps.

RAM slots

How much RAM do you plan to put on your board? Usually this will depend on what you are using the laptop for.

Most ATX and Micro-ATX motherboards come with four RAM slots.

There are also high-end HEDT boards that can hold up to 8 slots for tough tasks.

However, for common productivity tasks and games, you don’t need as many RAM slots. Four will probably be enough. Some boards come with just two slots that you can still install up to 32GB of RAM. The problem is that boards that come with only two slots that support 16GB each are more expensive than those with 4 slots that support 8GB each.

So in most cases, you’ll want to stick with a board with 4 RAM slots that support up to 64GB.

Expansion slots

Most modern motherboards only come with two types of expansion slots:

  • PCIe x1 – Short and mainly used for SATA and USB expansion.
  • PCIe x16 – Longer and used for things like graphics cards and SSD storage.

Most ATX and Micro-ATX boards come with enough expansion slots for conventional gaming and productivity tasks.

They typically offer no less than one x16 slot and a few more x1 slots. These are sufficient to support some SATA / M.2 drives, a sound card, and a video or graphics card.


If you are looking for a mainstream motherboard that supports only one graphics card and a few drives, any chipset from Intel’s Z390 category would be a good choice. Some chipsets like the H370, H310, and B360 don’t support overclocking, so you’ll want to steer clear of them if you’re looking to boost your clock speed.

In this guide, we focus solely on the Z370 and Z390 chipsets, all of which support overclocking. However, if you are looking for features such as USB 3.1 support, you may need to go for newer but slightly more advanced chipsets like the H370 instead of the Z370.

Overall, the Z390 offers the best features with overclocking capabilities, so this chipset will be a great companion for the i5-8600K.


As a general rule of thumb, you can only overclock CPUs that end with a “K” in your model names. Luckily for you, the i5-8600K fits into this category. In this case, you will only need to look for a motherboard that can overclock. These are mostly those with Z370 and Z390 chipsets .

All of the motherboard recommendations in this guide support overclocking, so you won’t be looking too far before you can find the best option.


We hope this guide will put you on the right track to find the best motherboard for i5-8600K . We’ve done a lot of research to make sure our recommendations fit a variety of budgets and needs.

Be sure to check if the board you are buying meets your specific needs based on the considerations outlined in this guide.
