Best Motherboard For I9-9900k – Buyer Guide

So, you are probably still thinking about which motherboard to choose. We don’t blame you, you still don’t know much about them. Well, here we will help you with that.

Here are all the most important factors to think about before making your final decision. Have a look:

Chipset and socket

Currently, there are only two chipsets available in most motherboards that work with this processor: the Z390 and the Z370. Indeed, the Z390 is the most reliable and powerful. That is why the best z390 motherboard for i9 9900k you can get will make the PC work better.

However, don’t forget about the plug. You need an LGA1151 on the MOBO to install the i9 9900K correctly. However, it is very likely that you will not find a similar motherboard with a different socket today. Still, be very careful.

Overclocking Capability

Overclocking ability will come from several different factors that you will need to consider. First, it will be the VRM of the motherboard. This refers to the way it transforms regular voltage into something that the CPU and GPU can handle. Here, we recommend quality VRM systems with 12 + 2 phases for additional results.

Next, you will have to consider the proper quantity and quality of heat sinks. Additional sinks will be needed to keep your RAM, CPU, M.2 SSD, and VRMs or capacitors cool. They will prevent each overclock from overheating and burning the machine.

Other overclocking features like easy-to-use BIOS systems, automatic fan functions, and booster software that come with MOBO are worth considering. The easier, safer, and more convenient to overclock with MOBO, the better your experience with an i9 9900K will be.

Expandability and ports

If you want the best motherboard for intel i9 9900k then you need something with enough ports. Here, you will need to consider PCIe ports for GPUs, DIMM slots for RAM (DDR4), and M.2 ports for storage.

For example, if you want to build a super gaming PC with multiple graphics cards, you will need multiple PCIe ports. If you want at least 32GB of memory capacity, go for something with 4 RAM slots, or go for something that can handle 32GB per slot. And lastly, consider at least 2 M.2 ports for SSD. You can choose the RTX 2080 Ti graphics card for excellent gaming performance.

However, don’t forget the USB 3.0 and Ethernet ports. And the extra USB ports plus an HDMI connector never disappoint.


For the best experience, always remember to choose a motherboard with stable Ethernet and fast WiFi adapters. At the same time, consider Bluetooth as an extra capability. If you can connect to the internet via NFC or any other wireless connection besides WiFi, then it’s a great addition to think about.

Size / form factor

The best ATX motherboard for i9 9900k is big and spacious enough to support multiple PCIe ports. However, it can be difficult to fit into small boxes.

That’s why you can also consider a mini- ATX or mATX, which offers a slightly smaller MOBO design that fits in compact cases. They save tons of space but come with fewer ports and slots.

Audio and RGB

Then you will find the audio. Nothing compares to a good-sounding PC that doesn’t need a sound card. You can enjoy high-quality audio directly from the motherboard, offering the ability to connect a 7.1 home theater without losing any of the quality.

Another extra to consider is the RGB system. With enough lights and attractive strips, you can make even the dullest cases look more attractive. And you will have a very exciting PC at home.

Best Motherboard For I9-9900k – FAQ’s

Can I install other processors on these motherboards?

Yes, as long as they have the same socket (LGA1151) and the same chipset (Z390) as the i9 9900K, they will probably work without a problem.

What is the difference between a normal motherboard and a gaming one?

Not really. RGB lights are primarily for aesthetics. However, it’s safe to say that they can allow for better identification of the components within the box. But that’s just a side benefit.

How much should I spend on a motherboard for i9 9900K?

You can find super affordable MOBOs under two hundred. But if you really want to harness the true power of an i9 9900K, you’ll need to spend at least three hundred.

What is the relationship between VRM and heat sinks?

A VRM or also known as PPM is a small converter that transforms the supply voltage so that the processor can handle the load without problems. The heatsink is a piece of metal that cools these converters and other parts of the motherboard to prevent burning.


So, are you eager to build your new PC with a powerful processor? Then don’t hesitate and get the best motherboard for i9 9900k.

Use our recommendations and buying guide to get the ideal model for your needs. There is one for every purpose and demand. So choose wisely and take your PC performance to a whole new level. You will not regret it.
