Best Motherboards for Core i9 9900k in 2023

In 2018, Intel launched another sequel to its predecessor known as 9th generation processors, which uses coffee lake architecture. Its presence stimulated an odd enigma that forced contemporary gamers to dive into a new environment. As the title suggests, this article will discretely focus on the i9-9900K processor, where “K” represents the unlocked processor (overclocking). The 9th generation processor requires extremely competitive hardware, which can support the high-end features of the processor.

For example, you will be in dire need to have a motherboard that harbors the process of sufficient overclocking (boasting core speed) and incorporating the latest hardware and sustainability over time.

Since these unlocked processors run hotter, you will have to ensure decent airflow into the system. For that, your motherboard should have slots for coolers, availability of SATA to IDE expansions, and system fan slots. The key element here is “Cooling.” The reason is quite fathomable because whenever you boast a component that exceeds its manufactured value, it will simmer. To reduce the simmering, what you will have to do is find the best compatible motherboard for the processor. Before that, we will be talking about a couple of things to bear in mind before pushing ourselves to the checkout. Click Here to Read what factors to consider before buying a MOBO for i9 9900k.

We will proceed to the most-awaited session of finding the best gaming motherboards for Intel Core i9 9900K.

What factors to consider before buying a MOBO for i9 9900K?

You are setting up an example for the current generation, especially gamers, about the motherboard selection criterion. Albeit, you are making progression; at the same time, there are chances that you might end up with the wrong motherboard. How to minimize such erroneous happenings? The only way to purge out the possibility of making the wrong choices is to ensure that XYZ features are present in the motherboard. For that, I have enumerated all the required features you need to look at.

• Chipset and Socket: Engrave this on your mind: Core i9 9th generation processor only supports Z390 and Z370. If you are going for any other motherboard, then sorry to say, you will not be able to run the chipset. In the latter part, we will be mostly focusing on Z390 and its myriad of features that enable customization and freedom of choice. Wait, we are not over yet with this bulletin. For the socket, you are required to get an LGA1151. If by luck, you end up selecting another socket on either of the motherboards, then all you can be is apologetic to yourself.
• Expandability (ports): It’s another crucial factor to consider before finalizing any motherboard for your chipset. Let me explain this to you with an example. Suppose, you got the best motherboard for Core i9 9900K, but unfortunately, it lacks the expandability factor. The real question arises, what do I mean by expandability? Surely, you will not be upgrading the system anytime sooner; thus, requiring you to have a series of ports installed on your motherboard already. These ports allow you to have upgrades without taking a toll on your savings. For example, in the future, you want to slot in another GPU. How would you do that? It will only be possible if your motherboard has extra PCIe slots on it.
• Overlocking Capacity: Who doesn’t want this? If you are an enthusiast gamer, then the factor of overclocking shouldn’t be overlooked. It allows you to harness the maximum potential power of each slotted component on the motherboard. When you game, code, and render, you need those boosted frequency clocks to make things happen faster, and it’s only possible if your MOBO supports the overclocking feature. For cross-checking, you will be required to look at VRMs, the number of heat sinks attached, and the profiling setup in the BIOS. 
• Form Factor: At times, people usually forget even to check the form factor of the motherboard. What happens is that they cannot fix the MOBO into the case because they were so oblivious to their surroundings. I hope you are not like them (fingers crossed). In short, motherboards come in three discrete form factors: ATX, Micro ATX, and Mini-ITX. If your case is compact and portable, I recommend you go for either micro ATX or mini-ITX form factor.
• Connectivity: How could you forget this? For the immersive gaming experience, you need stable ethernet ports and fast Wi-Fi adapters, and it’s only possible if your motherboard offers these value-added features. Not to mention, some motherboards offer in-built Wi-Fi if you can get them, then well and good.
• RGB: It’s not like you are forced to get this option available to your motherboard. Well, using RGB is your personal choice. If you are out of budget and do not want to buy expensive motherboards, just for the sake of lighting up your room in pink and blue, it’s okay. Non-RGB Motherboards will work fine!

Wrapping Up

To wrap up, if you are looking forward to overclocking your i9-9900K to its full potential, Gigabyte Z390 Aorus Xtreme is the best pick-up for you. Why though? Although the price tags continuously vary, the supporting features give the motherboard an enticing look. Just imagine running your new beast high-end PC, with all the components overclocked. In addition to that, you can install two coolers on your motherboard, if the case has the required space. Suffice to say, this Gigabyte Z390 Aorus Xtreme has everything you have dreamt of. 

Conversely, if you are looking forward to something between the lines, then ASRock Z390 Pro4 might help you out of your budget misery. It’s a good-looking and average motherboard with most of the advanced features. 

I hope the guide was easy to comprehend and understandable. If you have any queries regarding selecting the best motherboard for your system, feel free to comment.
