What to Look for Before Buying a Motherboard for i9 9900K?

So you’re probably still thinking about which motherboard to choose. We’re not blaming you, you still don’t know much about them. Here we can help you to find all of the major factors to think about before making your final decision.

Chipset and Socket

Currently, only two chipsets are available in most motherboards that use this processor: the Z390 and the Z370. Of course, the Z390 is the most reliable and powerful. That’s why the best z390 motherboard for i9 9900k you can get will make the PC perform better.

Don’t forget about the socket, though. You need an LGA1151 on the MOBO to install the i9 9900K properly. Yet, you’re pretty likely not to find any similar motherboard with a different socket nowadays. Still, be extra careful.

Overclocking Capacity

Overclocking ability depends on several factors that you need to consider. First of all, it will be the VRM of the motherboard. This refers to the way the regular voltage is converted into something that the CPU and GPU can handle. Here we recommended high-quality 12 + 2 phase VRM systems for additional results.

Then you need to consider the correct quantity and quality of heat sinks. Additional sinks are required to keep RAM, CPU, M.2 SSD and VRMs or capacitors cool. This prevents any overclocking from overheating and burning the machine.

Other overclocking functions such as user-friendly BIOS systems, automatic fan functions, and booster software that are supplied with MOBO are worth considering. The easier, safer, and more practical the overclocking with the MOBO is – the better your experience will be with an i9 9900K.

Expandability and Ports

When looking for the best motherboard for Intel i9 9900k, you need something with enough ports. Here you 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’ll need multiple PCIe ports. If you need at least 32 GB of storage, choose 4 RAM slots or 32 GB per slot. Finally, you should consider at least 2 M.2 ports for SSDs. You can choose the RTX 2080 Ti graphics card for great gaming performance.

Don’t forget about USB 3.0 ports and Ethernet, though. And 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 additional function. If you can connect to the internet using NFC or any other wireless connection besides WiFi, this is a great addition to think about.

Size / Form Factor

The best ATX motherboard for i9 9900k is big and roomy enough to support multiple PCIe ports. However, it can be difficult to fit into small cases. For this reason, you can also consider a Mini-ATX or mATX, which offers a slightly smaller MOBO design that fits in compact housings. They save a lot of space but have 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 straight from the motherboard, allowing you to connect a 7.1 home theater without missing a beat. A little bit of quality.

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


These are the best motherboards for the i9 9900k, and I would recommend you to get anything according to your budget from this list.

If you’re looking for a motherboard to put it together with the Core i9-9900K for a normal-sized PC build and want great overclocking capability and a great set of features with enough space as well, then you should definitely check out the Gigabyte Z390 Aorus Xtreme motherboard, however, it is a bit expensive.

This motherboard has a large voltage regulator for increased power output, which helps when overclocking your CPU. This motherboard also has great features.

If you’re looking for a compact-sized motherboard to pair up with Core i9-9900K and want to get most of the features that a high-end user wants, then you should check out the ASUS ROG Maximus XI Gene. It has the good overclocking capability with a great set of features which makes it a great choice to pair up with Core i9- 9900K; however, it does not support dual graphics cards.

If you simply want a high-end system that has everything that a high-end user may need and don’t care much about budget and are looking for a motherboard to pair up with the Core i9-9900K, then you should definitely check out the MSI Meg Z390 GODLIKE motherboard.

If you’re not much into the “gaming” hardware and want a motherboard to pair up with the Core i9-9900K having a simple design with good performance and a good set of features that will perform really good and isn’t much expensive, then you should definitely check out the Gigabyte Z390 UD.

Finally, these motherboards are some of the best motherboards for i9 9900k, and my final recommendation would be to go for the one that fits your needs and budget.


Is the i9 9900K overkill?
If we strictly speaking about this as a gaming computer and nothing else, then yeah, it definitely it is. I would only go for i9 if I am a successful streamer and professional gamer and also, render video clips on the side. The 9900k is overkill compared to the 8700k (which you can decide a lot easier). Games are starting/have started to utilize 6 cores and some titles like strategy games going higher.
Is it worth upgrading to i9 9900K?
A stock 9900K probably won’t feel slow for a while. Even 3-4 years from now it’ll still feel solid. You’re probably set until they start releasing their 7nm chips. Anything below 12 cores is not worth upgrading to from a 9900k. For gaming, it is probably a waste upgrading to the 9900K already. The increase in performance would only be visible in some select games. For the most part, it would be so similar that you couldn’t tell there’s a faster CPU.
How much RAM do I need for i9 9900K?
If you are exclusively gaming and have no plans to make or render videos 16GB of ram is the sweet spot. On Intel, CPUs ram provides very minimal performance gains so there isn’t much reason to go for ram speeds above 3000 or 3200. 16 GB 3200mhz is the best bang for your buck.
Is 3900X better than 9900K?
The Core i9-9900K has a base frequency of 3.6GHz and a maximum boost frequency of 5GHz, compared with the Ryzen 9 3900X’s base 3.8GHz speed and 4.6GHz maximum boost. Here, at least on pure specs, the Ryzen 9 3900X wins hands down. It comes with support for 3,200MHz DDR4 memory and a whopping 70MB L3 cache on the die.
Does i9 9900K need liquid cooling?
It Depends on your CPU, if you won the silicon lottery, you will be able to do 5Ghz with very low voltage – ~1.2v If not, then you will need more voltage, which means more heat which eventually means you need a stringer cooling solution. First, look for a Noctua tower or water AIO, and see how your CPU runs. Then you will know if it is worth or not investing in better cooling.
