The Core i9 – 9900K was a beast and, even to this date, holds up against the top CPUs. The eight-core Core i9 is robust, thanks to engineers at Intel. It is the refreshed Skylake architecture but still performs strongly in 2020. The Core i9 uses the same old 14nm fabrication and has a lot of power draw to produces a lot of heat. But if you can set aside those factors, this is the right CPU for the price.
A high-end CPU will need a better motherboard. Using a cheap or knockoff motherboard isn’t going to bode well with the processor. So we have accumulated a list of the best motherboards for your Core i9 – 9900K. Each motherboard on the list is specifically handpicked, looking at the price point and functionality.
9th Generation Core i9 CPU and its SKUs:
The Core i9 is Intel’s top of the line processor. Intel provides the highest number of cores with aggressive clock speed timing. The Core i9 is the highest of the bunch but has tons of SKUs, confusing to average consumers.
The Core i9 comes in 7 different SKUs, but we are focusing on the Desktop variants. There are four desktop processor SKUs in the market. All the processors have the same Core i9 – 9900 naming. But the suffix on the name distinguishes each of the Core i9 lineups.
“K” – Unlocked, the processor is overclockable.
“F” – Comes with no integrated GPU
“S” – Special CPU with higher clock speed “Hand Picked Faster CPUs.”
Core i9 SKUs:
|Processor||Base Frequency||Boost Frequency||Cache
|Core i9 – 9900KS||5.00 GHz||4.00 GHz||16MB Intel Cache
|Core i9 – 9900K||5.00 GHz||3.60 GHz||16MB Intel Cache
|Core i9 – 9900KF||5.00 GHz||3.60 GHz||16MB Intel Cache
|Core i9 – 9900||5.00 GHz||3.60 GHz||16MB Intel Cache
Is it wise to get i9-9900K in 2020?
i9-9900k’s direct competitor, Ryzen 9 3900X comes with 12 cores and 24 threads. AMD has an upper edge on the multi-core workloads, but Intel has the upper hand on the single-core performance. Intel beats the Ryzen 3900X with exceptional gaming performance to score high FPS in 1080p and 1440p gaming scenario.
|Intel Core i9 9900K||AMD Ryzen 9 3900X

|Boost clock speed||4.7GHz (all cores)|
5GHz (one core)
|4.1GHz+ (all cores)
4.6GHz (one core)
|Graphics||Intel UHD Graphics 630||No|
But the Ryzen 9 3900X has more cores better for content creator work. Prices have come down a lot, and the Core i9 – 9900K comes for around $500, a lot cheaper than Ryzen 9 3900X. But if gaming is your main task, the Core i9 is fitting. Or whether you are upgrading from a Core i7 on a Z390 motherboard, it is a good bet. Plus, it has more cores than Core i7, which might come in handy.
But there are stock issues on both Ryzen and Intel front. Intel looks to discontinue the Core i9 9th gen soon, and there isn’t a fair upgrade path. So buying a new system doesn’t fit the choice. But if you don’t look to update your system in the next 6 years and solely look at gaming, the Core i9 – 9900K is a great CPU.
But if you want more performance, longevity with an upgrade path, the Ryzen 9 3900X is looking good on all fronts.

The USB ports have two full USB Type-C with USB 3.1 Gen 2 with Thunderbolt 3 support. It has 2 x USB 3.1 Gen 2 and 2 x USB 2.0 ports on the motherboard’s back.
So the Core i9 – 9900K is expensive hardware, but now it has lowered its price. The Core i9 – 9900K requires a powerful motherboard with a stable VRM configuration. Plus, there are tons of options on the market as it uses the normalized LGA 1151 socket.
Chipset and Socket:
The Core i9 – 9900K uses the standard LGA 1151 socket, standard across 8th gen and 9th gen platforms. Usually, the 9th gen processor is supported on the B360, B365M, and Z390 motherboard.
B360 Motherboard and B365 Motherboard:
The B360 motherboard and B365 motherboard are similar in specification, with minor changes here and there. The B360 and B365 motherboard is based on the 300 series chipset. They have the same LGA 1151 socket, same power draw. But the B360 has fewer PCIe lanes than the B365 motherboard. The B360 comes with 12 lanes, whereas the B365 comes with 20 PCIe lanes.
They do not support overclocking as they are the basic motherboard supporting the Core i9 – 9900K CPU. There are only a handful of motherboards that support the Core i9 processors. They have an exorbitant price tag making the Z390 motherboard more viable. So please avoid the B360 and B365 motherboard when building a Core i9 system.
So there is a middle-man between the B360 and Z390 motherboards. The H370 is the mid-range level motherboard in the 300 series platform. They offer similar features like the Z390 motherboard lacking overclocking features. The H370 motherboard uses the LGA 1151 socket.
It doesn’t support overclocking, making it a cutdown version of the Z390 motherboard. The H370 comes with 24 PCIe lanes and VRM powerful enough to handle the Core i9 – 9900K. If you are not looking to overclock the motherboard, then this is the best bet for you.
The Z390 motherboard is the flagship tire of the 300 series Intel Chipset. It supports all the high-end processors from the unlocked Core i9 to the Core i3 CPUs. It offers more lanes for expansion slots and fully supports overclocking.
The Z390 motherboard has 24 PCIe lanes supporting a wide range of the expansion cards like GPU and wifi. But the motherboard tends to be more expensive as it opens all the tentative features of the Core i9 processors.
Plus, you are getting a hefty VRM and MOSFETs arrangement allowing you to attain higher clock speed when overclocking. The power delivery can stabilize the voltage to the CPU, increasing the components’ longevity—the best choice for enthusiasts.
Overclocking, in general, is pushing your hardware with additional power to boost its performance beyond their intended limitations. In the case of CPU overclocking, the CPU is introduced to additional power from the motherboard increasing its clock speed. The higher the clock speed, the faster and better the CPU’s performance.
But not all motherboards are made for overclocking. Overclocking a CPU isn’t suggested as it degrades the component’s lifespan, and overvolting the CPU might cause the part to fail. So expert advice is needed to overclock the CPU.
Talking about the overclocking capacity depends on the VRM and the MOSFETs present on the motherboard. The VRM and MOSFETs feed voltage to the CPU regulating voltage. A good VRM can provide stable voltage to overclock the CPU.
As for overclocking, anything above 10 phases VRM can push the 9900K over 5 GHz (single-core), but if you want to attain higher levels, please consider anything above 16 phase VRM. Overclocking needs precise power management. Consult experts before performing any sort of overclocking.
Expandability and Ports:
The expandability and the ports on the system wholly depend on the user and the type of work. Gamers might need just a few expansion ports and USB ports, whereas Creators frequently change or add components so that they might need a better motherboard.
If you are a gamer, you might not need a lot of expansion slots. A motherboard with two 16x PCIe slots does the job. Previously SLI on consumer graphics cards was the talk of the town, but now SLI is entirely dead. It is great to have 3 – 4 expansion slots, but two 16x expansion slots are sufficient for now. Plus, you don’t need much high-speed USB Type-A port, 6 ports are enough for gamers, plus the front panel USB is connected to the motherboard.
Creators and streamers require a lot of PCIe lanes. A graphics card is mandatory in the system, and additional cards like Streaming cards, storage expansion cards, wireless cards, etc. Adding all those ain’t viable in two 16x slots. A motherboard with four 16x expansion slots and two 1x expansion slots is needed for content creators and streamers alike.
Plus, higher-end Quadro cards support SLI boosting performance in 3D/ Animation work. So a creator looks for boards with more PCIe lanes rather than gaming-centric boards. A creator might need to work with many peripherals, so a board with a lot of USB suits them a lot. The Thunderbolt 3 support is excellent, but only power users take advantage. To an average user, it is just a luxury feature.
Size / Form Factor:
Every motherboard comes in different shapes allowing more or fewer features in it. The overall build also dictates which you are going to use. It comes in various form factors, e.g., E-ATX, ATX, MATX, ITX, MiniITX, etc. The ATX is taken as the standard form factor motherboard.
For the mid-tower cases, the ATX and EATX form factor is the best. They have a fair amount of PCIe Lanes and better I/O selection. ITX and MiniITX are for compact builds, so fair enough to make it portable. So for each build, there are sized boards.
What’s the difference between a normal and a gaming motherboard?
There isn’t much difference between a normal and a gaming motherboard. Looking at the specifications, there is much to none difference between a normal and gaming motherboard. They feature the same VRMs, similar performance, and power draw.
Most of the difference comes in aesthetic, RGB lighting, and eccentric gaming features like extra RGB Fan header or fancy gaming gimmick.
How much should I spend on a motherboard for an i9 9900K?
Every line of work has its caveat. As for everyday usage, a standard Z390 motherboard from $150 to $300 is enough. But for the professional and enthusiast, shilling more than $500 is excellent as it offers better VRMs and PCIe expansion slots. Get what you need; expending $700 for a gaming system isn’t great.
What is the relation between VRM and heatsinks?
The VRM is the Voltage Regulation Module, which regulates the voltage to the CPU. A VRM constantly regulates the voltage to the CPU, causing the production of heat. The heatsink comes into play to regulate the temperature on the VRMs. The heat sink dissipates heat from the VRM, preventing it from failure.
