The best motherboards for Intel Core i9-9900k processors

When it comes to building a new system, it’s easy to focus on the graphics card – especially if you’re an avid gamer. However, the motherboard is just as important and your choice can have a big impact on your PC’s ability to run games well.

If you have a 9th generation Intel processor or are planning to upgrade to one, choosing the motherboard is a critical part of your PC build. There are several things to consider, but the first thing to look at is the outlet. This is what the CPU is connected to so you need to check that it is the right size and compatibility before buying. The Intel Core i9-9900K has a LGA 1151 socket type, so your motherboard must have the same socket.

The best motherboard chipsets for this processor are usually the Z390 motherboards. Therefore, they will of course take first place on our list today.

In addition, we take a look at some of the key areas that you want to consider when considering a new motherboard. This is ideal for those who can be a little rusty. Let’s start with a quick look at the motherboards we’re going to cover today.

How we choose

At WePC we know how difficult it can be to choose the best components for your PC. You always want to do it right, but there are so many things to consider. It’s hard to know where to start. This is where we come in. We put together a number of components that we recommend to help you make the best possible decision for you.

But how do we choose? We examine countless reviews, comparison videos, benchmarks and specifications so that we can put all this information together for you in an easy-to-understand way. If possible, we are happy to test the motherboards ourselves and post reviews to get more detailed information.

If you’re tired of crawling through hundreds of reviews and articles, you’ve come to the right place. We give you an overview of what to expect with each motherboard so that you can make a decision without any problems.

Things to watch out for

What budget should I set for an Intel Core i9-9900k motherboard?

The first thing to consider is often the price of the component. With so many options, this means that you should be able to find budget options for medium or high level options. If you clarify your budget, you can narrow down your selection.

However, if you’re looking for an idea of ​​how much a Z390 motherboard will cost, high-end motherboards can range from $ 200 to $ 500 and sometimes over.

These costs are determined by a number of factors such as the number of available ports, PCIe support, the form factor and other functions such as RGB lighting.

Form factor

Once you have an idea of ​​the budget, the next thing to look at is the size of the motherboard. Motherboards are usually available in different sizes, as are PC cases. If your case is smaller, you may need to rethink the full-size motherboards and use a mini-ITX instead.

The last thing you want is to buy a motherboard that will make your case feel a little crowded – or worse – not fit at all. This also affects the size of some components that you can also install. With less space, you have difficulty fitting into a large graphics card.

Motherboard form factor

Most motherboards come in one of the following form factors:

  • Mini-ITX – 6.7 “x 6.7”
  • Mini ATX – 5.9 “x 5.9”
  • microATX – 9.6 “x 9.6”
  • ATX – 12 “x 9.6”
  • eATX – 12 “x 13”

Socket type

The type of socket on your motherboard is also an important factor. A socket is the part of the motherboard where your processor is located. It is therefore important that it fits. Different CPUs have different socket requirements. For example, one of the newer 10th generation processors requires a LGA 1200 socket.

However, if you are using an Intel Core i9-9900K, you will need a motherboard with an LGA 1151 socket. If not, it just doesn’t fit and you have an expensive motherboard and CPU and have to decide which ones to send back.

If you choose an AMD processor, you need a motherboard that supports a completely different socket. In the case of AMD, it is an AM4 socket that you would need in most cases.


Another important point is the chipset of the motherboard. The chipset on a motherboard determines a few things, including the number of PCIe lanes available, the SATA ports, and the ability to overclock your system.

The Z390 chipset is recommended for Intel Core i9-9900K CPUs. This is covered in this article. The Z390 chipset should offer space for expandability in the future. This is one of the reasons why it is recommended for 9th generation Intel processors.

Available ports

When comparing motherboards, you should also check the number of available ports and their location. These are required to connect things like a mouse and keyboard, but also headphones and USB devices. It’s important to have a good number of ports so that you don’t get stuck without something to connect your devices to.

Some of the most common ports to look for are:

  • USB Type C.
  • USB 3 / USB 3.1 Gen1
  • USB 3.1 Gen2
  • HDMI
  • DisplayPort
  • Flash 3
  • Audio connections
  • PS / 2 connections

Expansion slots

Expansion slots can be used to insert a number of PC components, so the number of available components is also important. Most standard motherboards have enough slots for a graphics card, a sound card and some M.2 drives. However, if you want to run additional components such as another graphics card or a video recording card, you must check whether the slots are available.

You should also look at how many high speed I / O tracks your motherboard can support. Sometimes motherboards disable some connections to support multiple components. For example, SATA ports can be disabled if you connect something to the M.2 slot. This can lead to all kinds of confusion if something doesn’t work.
