Best Motherboard for i9 9900K

Want The Best Motherboard for i9 9900K Advice?


Core i9-9900k is a formidable processor that runs intensive tasks including video rendering, editing, and gaming among other tasks. A CPU this powerful needs a solid motherboard to match, otherwise, you won’t get the best of it. You’ve gone for a great graphics card and the other usual upgrades. Let’s find the best motherboard now.


If you’re looking for a motherboard with great overclocking capabilities, budget buys, or one that sports the latest features, we’ve got you covered with the best motherboard for i9 9900k review.


What is a Motherboard?


I’m sure most of you know what a MOBO, but this is for the sake of the newbies, trying to build their first pc (we’ve all been there). The motherboard can be thought of as the heart.


Motherboards typically sit at the back of the machine and their primary function is to route power to all the parts of your computer and help them communicate with each other. As such, it has physical contact with nearly all the components on the PC—think main power, CPU, RAM slots, video and sound cards, PCI, USB, and expansion slots.


Motherboards also play a vital role in upgrades. If you want to go that route its important to first check for compatibility since not all motherboards have the correct connections for the newer models. You can also upgrade your motherboard to facilitate other improvements such as a new CPU or a video card.


What to Look for in a Motherboard?


Choosing a motherboard can feel intimidating at first which is why we’ve put together a list of factors that you should consider before making a purchase


1. Form Factor


In simple terms, this relates to the size of the MOBO. There are three main sizes available:


  • ATX: Most motherboards come in this size and it offers the most space for slots and plugs
  • Micro-ATX: The name says it all. Micro-ATX is shorter than the standard ATX and offers less space for expansion slots
  • Mini-ITX: This size is suitable for tiny PCs. It offers fewer storage options and may have room for only one add-in card.


2. Processor Socket and Chipset


The CPU socket refers to the solitary connector between a MOBO and a microprocessor. It’s a distinct mount on the motherboard used by the CPU only and it ensures the circuit chip is inserted correctly. It aids CPU access and inhibits damage that may be caused by the insertion or removal of a unit.


It’s worth noting that CPU sockets are designed for specific CPUs and they aren’t interchangeable. Intel works with LGA sockets while AMD chips use PGA sockets. BGA is also a CPU socket, but one that’s not common since it’s bonded permanently to the motherboard which makes servicing or upgrading difficult.


For easy identification, manufacturers include a three to five-digit number which ensures a CPU uses the right CPU socket.


Two chipsets work with the Core i9 900k—the Z370 and Z390. Both chipsets facilitate overclocking features and provide quick access to data files, videos, and digital photos. The Z390 chipset is faster, more powerful, and ideal for intensive gaming.

3. Overclocking Capacity


Overclocking refers to pushing the CPU and memory to run at a higher speed than the official speed grade set by the manufacturers. If done right, overclocking may help speed up your system. It’s a risky affair since overclocking has the potential to destroy your MOBO, CPU, memory, or corrupt your hard drive not to mention voiding the CPU’s warranty.


If it’s so bad, why is it even a consideration? Because we all do it, ha. But seriously, if you run system-intensive applications like photo editing, video transcoding, and games, juicing up your CPU’s clock can boost performance.


Consider the motherboard’s VRM (Voltage Regulating Module) which converts regular voltage into something your processor and graphics card and handle. We recommend using a high-quality VRM system along with 12+2 Phases for good results.


Further, you can install extra (good quality) heatsinks to keep the CPU, RAM, Capacitors, and M.2 SSDs cold and prevent your machine from overheating and burning.

4. Expandability and Ports


If you’re building a gaming PC, with multiple graphics cards, you want to have several PCIe ports. If you’re inclined towards 32GB RAM, go for a motherboard that can handle 32GB per slot or one with at least 4 RAM slots.


Consider having at least 2 M.2 ports for SSD, USB 3.0 ports, extra USB ports, an HDMI port, and Ethernet. While we’re on the subject, fast Wi-Fi adapters, and Bluetooth capacity are invaluable additions.


 5. Audio and RGB


Many motherboards come with built-in features including onboard audio, but in most cases, you’ll find that it’s only good for mid-range speakers. If you want a bigger sound with good quality, and possibly one that you can link up with a 7.1 home theatre, you’ll need a sound card.
