The idea is to make a multi-core gaming chip capable of multi-threating by using the LGA 1151 socket and Z390 chipset. The other versions of i9 series have some minor changes and aren’t considered best for gaming.

The i9-9900k chips comes with base clock frequency of 3.6GHz which can be boosted up to 5GHz, eight CPU cores and 16 threats. This chip is a beast when you’re going to use it for gaming. The i9-9900k is very good at hyper-threating. These features make it the fastest chip as compared to any other AMP processors available in the market.

Motherboards are created in different types of sizes, some of the most commons are ATX, mATX (micro-ATX) and ITX (mini-ATX).

The ATX sizes are the full size motherboard comes with more than two PCIe slots which will allow you to install multiple graphics cards at a time. These ATX boards are big, that’s why it’s not a good fit for small cases.

The mATX (micro-ATX) motherboard is 25% smaller than a normal ATX motherboard. Due to its smaller size, it has one or two PCIe x16 slots, and it has a PCIe x4 expansion slot which will allow you to install multiple GPUs in one casing. These motherboards are normally designed for medium PC builds. The rear I/O panel of mATX is identical to normal size motherboards, so you can use your mATX motherboard in you full size PC builds too.

The ITX motherboards are used for comparatively small builds, but they are not very good at gaming, thermals and overclocking your processor to its maximum limits. These motherboards come with only one PCIe x16 slot. You’ll need a very small pc case to make it a good fit.

Chipset & Socket

There are only two chipsets in the market on which the Core i9-9900k chip works well – the Z390 and Z370. The Z390 is however the latest and the most powerful chipset, which will allow you to overclock your processor to its maximum limits.

Overclocking Capacity

There are several factors on which the overclocking capacity of a motherboard is calculated. Talking about the first one is the VRM of the motherboard. These are voltage regulator modules which sent the voltages to the CPUs and GPUs. These VRMs controls the voltages gives to the processor and graphics cards to avoid short circuit or a burnout. VRM plays the most important role while overclocking a CPU to its maximum limits. We suggest a 12+2 power phases to get the excellent results.

Cooling system on a motherboard is also an important thing for overclocking you CPU. The right quantity and quality of heatsinks will prevent your motherboard from over-heating and sometimes burning out your machine. Consider a motherboard with extra heatsinks on CPU, M.2 SSDs, and the VRMs or capacitors to keep your machine cool while overclocking.

Some optional overclocking features are like easy-to-use Bios, Auto fans controls, and the software which boosts your motherboard’s overclocking capacity. This software normally comes with your motherboard; these software gives great results. Moreover, the safer and the practical work provides you great results with i9-9900k.


If you are making the best gaming rig, always look for the best Ethernet and fast Wi-Fi adapter. Ethernet cables also plays a good role for making you connection more stable and fast. You can also consider Bluetooth adapter as an optional choice.

An ATX motherboard provides you the ability to install more than two graphics card, and you can increase your RAM memory up to 64GB. For storage, there should be at least two M.2 post to plug in your superfast SSD drives.

On the rear I/O panel, there are a lot of options, but for a good build there must be at least three USB 3.1 Type-A port as well as a Type-C port will gives you the ability to transfer your data at the maximum speed possible. Ethernet and Wi-Fi are the top priorities to be taken care of, because these adapters can give you smooth gaming experience while streaming.
