Buying Guide for the Best Motherboards for i9 9900K in 2023

Selecting the best motherboard for your Intel i9 9900K can be a difficult task. Luckily this guide has provided you with all of the most important information needed to make an educated decision about which board is right for you! There are a lot of factors that go into finding the best motherboard, and some people don’t know what to look for! If you’re looking for an Intel i9 9900K compatible board with plenty of options then we have just the list for you:

? Form Factor

The motherboard form factor tells you what type of motherboard it is. For example, an ATX form factor will be compatible with most tower cases while a Micro-ATX or Mini ITX will be used in smaller cases like an HTPC (Home Theater PC).

? Chipset

There are two chipset options to choose from: Intel and AMD. Neither one is better than the other; it all depends on what you want the board to do. If you want something to game or overclock on, then go for Intel. If you want something to overclock but don’t care about gaming, then AMD is your best bet.

? Socket

LGA 115x socket motherboards are cheaper but have fewer features. LGA 2011, on the other hand, is more expensive but it offers better stability and performance for overclocking. They both offer four DIMM slots so you are free to upgrade your RAM whenever you want.

? RAM Capacity

Motherboards come with different maximum capacities of RAM that vary from one manufacturer to another. It’s important to always check what kind of memory can be installed in a motherboard before purchasing anything since if they’re incompatible then no amount of money will help fix that problem!

? PCI-e Slots & Expansion Slots

The number or type of expansion slots should depend on how many graphics cards or USB devices you need the board to support at once (or over time). Most people won’t have an issue with these but if you’re looking for a motherboard to support multiple graphics cards, then those boards will cost more.

? Storage Options

There are two main storage options: SATA and M.SATA (some motherboards also offer both). The former is much slower than the latter so it’s not worth going over this in detail as most people don’t use either of them anymore. It mainly depends on how many devices you plan on using at once.

? Ports

Motherboard ports depend primarily on which chipset your board uses since they each come with different types of USB connections or even wireless connections! If you want to connect your computer up to your game console, TV set top, speakers, etc. then it’s important to consider the ports available on your motherboard first since some are better suited for certain tasks than others!


The basic input/output system or “BIOS” is what helps your computer boot up and start running when you turn it on. It also has other functionality such as overclocking, temperature readouts, fan controls, etc. that will help extend its life so be sure to take a look at this before purchasing anything unless there isn’t one (or if you don’t want an extra layer of control over how things work).

Are Best Motherboards for i9 9900K Worth It in 2023?

Yes, there is nothing to worry about using M.2 SSDs in Slot #1 and #3 simultaneously, they don’t interfere with each other and fit into the motherboard just fine without any problems.

Is there any advantage in buying a micro-ATX Z390 motherboard?

One advantage to buying a micro-ATX Z390 motherboard is that they’re typically cheaper and offer fewer features than the full-ATX one. However, this means that you’ll need an extra case to fit it in.

Can we buy a Z370 motherboard for Intel Core i9-9900K?

You can buy a Z370 motherboard for Intel Core i9-9900K and it should work. The only issue might be the chipset: on Z370, Intel has moved some of the security features to the CPU and on Z390 they’re also in the chipset. So if you buy a Z370 motherboard for an i9-9900K, you’ll have more of those features than if you bought a Z390 motherboard for an i9-9900K.

Are flagship Z390 motherboards worth their price?

It’s really hard to judge the worth of a motherboard in terms of pure monetary value. It depends on what you’re looking for with your motherboard, eg, what features you want. But when it comes to flagship Z390 motherboards, they are worth the price because of the quality and all the features that it offers.

Is there a way to overclock this i9 9900K with the best motherboard?

Yes, there is a way to overclock this i9 9900K using the best motherboard. You need to do 3 things for overclocking your CPU to make it perform at its highest performance:

  • Get a Z390 or X470 motherboard (which supports overclocking and fits all other compatibility requirements). Make sure to get one with an external clock generator because Intel didn’t use PLL circuitry in their Gigabit Ethernet controllers which means that those who have the required hardware can simply increase BCLK frequency. It also means that those motherboards without external clock generators feature could be limited by 10 MHz as compared to ones which boast such features.
  • Raise voltage but it is below 1.5V. It is really easy to do, all you need to do is simply raise the CPU Vcore voltage by +0.050V which will allow your CPU to hit 4.7GHz on air cooling.
  • Raise the CPU multiplier until you hit 4.7GHz on all Cores (this means that settings of this kind are more effective when used with unlocked or “K” CPUs). What’s most important about overclocking i9 9900k is to find a good enough CPU cooler because it can make a huge difference in temperatures while overclocking.
