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

So, you’re probably still thinking about which motherboard to pick. We don’t blame you – you still don’t know much about them. Well, here we’re going to help you with that.

Next, you’ll find all the most important factors to think about before making your final choice. Take a look:

Chipset and Socket

There are only two chipsets available in most motherboards today that work with this processor – the Z390 and the Z370. Sure enough, the Z390 is the most reliable and powerful one. 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 or an LGA1200 motherboard to install the i9 10900K properly. Yet, you’re pretty likely not to find any similar motherboard with a different socket nowadays. Still, be extra careful.

Overclocking Capacity

The overclocking capacity will come from several different factors you’ll have to consider. First, it will be the VRM of the motherboard. This refers to the way it transforms regular voltage to something the CPU and the GPU can handle. Here, we recommend quality VRM systems with 12+2 Phases for extra results.

Then, you’ll have to consider the right amount and quality of heatsinks. Extra sinks to keep your RAM, CPU, M.2 SSDs, and the VRMs or capacitors cold will be necessary. They will prevent every overclock from overheating and burning the machine.

Other overclocking features like easy-to-use BIOS systems, automatic fan functions, and boosting software that come with the MOBO are all 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

If you want the best motherboard for intel i9 9900k, then you need something with enough ports. Here, you’ll have 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 several graphic cards, then you’ll need several PCIe ports. If you want at least 32GB of memory capacity, then go for something with 4 RAM slots – or choose something that can handle 32GB per slot. And lastly, consider at least 2 M.2 ports for SSDs. You can choose RTX 2080 Ti graphics card for superb 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 go for a motherboard with stable Ethernet and fast WiFi adapters. At the same time, consider Bluetooth as extra capacity. If you can connect the internet via NFC or any other wireless connections apart from WiFi, then that’s an excellent addition to think about.

Size / Form Factor

The best ATX motherboard for i9 9900k is large and spacious enough to handle several PCIe ports. Yet, it may be difficult to fit inside small cases.

That’s why you may also consider a mini-ATX or mATX – offering 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’ll find the audio. Nothing compares to a well-sounding PC that doesn’t need a sound card. You can enjoy high-quality audio directly from the motherboard – offering the chance to connect a 7.1 home theatre without losing any bit of quality.

Another extra to consider is the RGB system. With enough lights and good-looking strips, you can make even the dullest of cases look more enticing. And you’ll have a highly exciting PC at home.

Frequently Asked Questions:

What’s the difference between a normal and a gaming motherboard?

Not really. The RGB lights are mostly for aesthetics. Yet it is safe to say they can allow better identification of the components inside the case. But that’s just a side benefit.

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

You may find super-affordable MOBOs at less than two hundred. But if you truly want to harness the true power of an i9 9900K, you’ll need to spend at least three hundred.

What is the relation between VRM and heatsinks?

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

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, then they will probably work without any issue.

Final Words

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’s one for every purpose and demand. So choose wisely and get your PC performance to a whole new level. You won’t regret it.
