How To Choose The Best Motherboards For i9 9900k

Now we believe, you have a clearer picture of the excellent motherboard to pick from. The next step is an easy one because we’re going to look at some factors for choosing the best motherboard for i9 9900k processors. Since you want only the best for you and this is why we are here for.

Motherboards For i9 9900k

1. Processor

You install a processor via motherboard connector So, it is important to choose a motherboard with the right connector for the processor you are using. And, the Intel core i9-9900k has the LGA 1151 motherboard socket. So go for an LGA 1151 socket to the CPU before lifting the motherboard.

2. Size

The case and motherboard have three forms, which offer adjustable sizes to your PC build. If, for instance, the game you are playing has no space restrictions, you can use a full-size gaming set. But, if you decide to install computers in your gaming room then you can go for the Mini-ITX or Micro-ATX form factor for lowering space. Big ATX motherboards generally have more options than mini and micro ITX motherboards. Keeping this in mind, you can choose which type of motherboard to select.

3. RAM

Even though it requires an operating system to perform the computing task, RAM will store all temporary information essential for the gaming speed. Many latest games require a large amount of memory to run efficiently. So, you must ensure you have enough memory to meet the specifications of your computer. When you are selecting a motherboard pay attention to the type of RAM along with the supported bus speed, which is DDR4 4200Mhz or DDR3 3200MHz. This implies its generation and bandwidth speed.

4. Storage

Latest PCs utilize SSDs especially for storage because of their extreme speed, so, check that your motherboard has the flexibility to deliver storage options. The latest storage ports deliver super-fast speeds through PCIe connectivity. Consider its availability and type before selecting a motherboard as per the storage requirements. To meet your storage requirements, try to find six SATA3 ports only.

5. PCIe Slots

To maximize the performance of your motherboard you have to choose what features your PC requires. In the beginning, you must verify the PCIe connectivity. The PCIe slot is the one that determines the number of reliable graphics cards and the amount of bandwidth you will use simultaneously. Since the majority of modern graphics cards weigh a lot, make sure that the PCIe slots get reinforced with metal.

6. Features

The latest motherboards have built-in functions that will save you lots of money and energy when installing any extra expansion cards. If you require one of these functions directly from the motherboard, consider this aspect.

7. Form Factor

Although this shouldn’t impact any performance issues with the Intel Core i9 9900K processor, however, you must still examine the form factor. Check that the motherboard is of the same size as your computer case. For instance, the ATX motherboard is specifically designed to fit ATX enclosures. We recommend you look in detail at other sizes like Mini ITX, MICRO ATX, EATX, etc.

8. Chipset

When you are looking for a motherboard to support the Intel Core i9 processor, it is crucial to make sure that the right chipset is installed on the motherboard. While there are many compatible chipsets that work with Intel Core i9, they require equally powerful motherboards. This allows you to overclock the processor and memory when needed.


The motherboard’s chipset is also equipped with its own software or a less powerful operating system known as BIOS. To get the best performance out of your computer, be sure to ensure that your system is stable and secure. So, make sure you check your motherboard’s support website to check if it’s regularly updated.
