Buying Guide – Best Motherboard For i9 9900k?

There is no doubting that a motherboard is one of the most vital components of any computer system; yet, this is a product that needs continual updating and maintenance. As a result, it is deemed imprudent to go all out for the motherboard and instead settle for a more mid-level device. For this reason, one of the best motherboard options for a processor like the i9 9900k is the ASRock Z390 Taichi Ultimate, which has been specifically developed for online gaming. This is underlined by the fact that it supports 10GB Ethernet, allowing you to stream and game with ease.

Talking about the key features, the Taichi Ultimate includes three PCIx16 slots, allowing you to install whatever GPU and sound card you desire. However, depending on your equipment selection, you may need to change and tweak the arrangement. It’s also worth noting that the lower slot is close to the RTC battery, so be extra cautious while inserting a card into that area. Another remarkable feature of the Taichi Ultimate is its ability to support up to six SATA associations. If you’re only using one M.2 space, you’ll need to use the next one as well because it includes SATA port 3. The first and third slots will each accept two SATA associations, 0/1 and 4/5.

Now that you’ve reviewed our top 5 selections for the best power supply for the i9 9900k, you’ll be significantly more prepared to tackle the daunting job of selecting a product for yourself. However, you may still be perplexed by certain facts and technical questions, which we shall address in the following questions. We will also highlight a few of the most crucial points to consider before making your purchase.

 

Figure Out How Much Power You Need:

It is critical to determine how much power an individual user need for their specific demands and system, as total performance is dependent on this. This may be simply confirmed using Newegg’s power supply calculator, which will help you figure out exactly how much force your new supply needs to provide. The tool is so good and exact because it considers all of the most recent advances, including new possibilities for the graphics processing unit (GPU), central processor unit (CPU), random access memory (RAM), and motherboard, among other things.

Make Sure Your Product Is Protected:

Many power supply manufacturers will partner with insurance companies to protect your parts against power-related issues. These assurances typically increase the cost of a power supply, but they also provide a great deal of peace of mind because you know your PC is adequately protected. The first is overvoltage assurance, which refers to a circuit or tool that shuts down the power supply unit if the yield voltage exceeds a predetermined voltage limit that is often higher than the estimated yield voltage. This assurance is important because high yield voltages can impair PC parts that interact with the power supply’s performance.

Make Sure The Product Is Certified:

When searching for power supplies, you’ll come across the 80 PLUS certification, which is one of the most widely recognised in the business. 80 Plus is a certification programme that allows manufacturers to certify that their power supply will fulfil specified performance standards. This is especially significant because a device like this does not come cheap, and you want something that will provide you with assurances of performance and quality.

Frequently Asked Questions (FAQ):

How many watts does an i9 9900k Use?

Intel uses a feature called Thermal Design Power (TDP) to depict how much power their CPUs produce, and it was determined that the i9 9900K is rated at 95 watts using this method. Even though this is accurate, the measure of intensity it employs varies greatly, ranging from less than 10 watts while inactive to more than 130 watts when operating at full throttle.

Is air cooling enough for i9 9900k?

Most CPUs nowadays can efficiently run Core i9 9900K at stock speeds with well-balanced temperatures, even when they are fully loaded. You can also overclock the Core i9 9900K to 4.9 GHz or 5 GHz on each of the 8 cores, and because air cooling is employed, it is sufficient to keep the temperature below 80°C or 85°C at those frequencies, and extra fans may be added if the airflow in the PC case is sufficient.

Is the i9 9900k good for streaming?

Choosing the ideal CPU for streaming means looking beyond a processor’s raw power or clock speed. A decent processor is the most basic instrument for guaranteeing consumers can keep up a consistent flow and excellent gaming execution when streaming at 1080p. That’s why Intel’s Core i7-9700K and i9-9900K CPUs are superb streaming options. However, offerings like the Ryzen 3000 CPUs have widened the chasm.

Is i7 9700k better than i9 9900k?

Both devices are powerful in their own right, but when compared, there is a tremendous gap in performance. While the i9-9900k outperforms its Intel competitors in multi-core performance, it falls short in single-core and quad-core performance compared to the i7-9700k. This difference is partially covered by overclocked rigs, where the margin is significantly less. This is significant because the i9-9900k is approximately 25% more expensive than the i7-9700k.

Does the i9 9900k need liquid cooling?

While it has its drawbacks, many users prefer liquid cooling for their CPUs. It is one of the finest ways to cool a CPU since water conducts heat better than air. Many customers prefer liquid over air for the i9-9900k because it keeps the PC cooler by eliminating the need for high RPM fans. However, liquid cooling can be risky if water leaks onto equipment.

What power supply do I need for i9 9900k?

With the i9 9900k, we recommend a 650-750W power supply with one graphics card. But for serious overclocking (running a computer’s processor faster than the manufacturer intended), 750W-800W is sufficient. A 1080ti can demand 300W, an i9 9900k can draw 320W, and other components of the system require electricity, totaling 680W-700W. So, for optimal performance and efficiency, use 75%-80% of the power supply unit. You will need to spend extra money on coolant if you want a PSU of 850W or 1000W.

What power supply is compatible with Intel Core i9-10900K and NVIDIA TITAN RTX?

An electrical power supply with at least 650W is required.

When it comes to the Intel Core i9-10900K, what is the power supply requirement?

The Intel Core i9-10900K processor requires a power source with a minimum power rating of 350 watts to function properly.

What is the power supply need for the NVIDIA TITAN RTX graphics card?

TITAN RTX requires at least 500W of power from its power supply, which is considered the minimum need.

 

Summary – Motherboard For i9 9900k?

A motherboard is undeniably one of the most crucial components of any computer system; nevertheless, it is also true that it is a product that needs continual updating and maintenance. This is why it is regarded advisable to spend a lot of money on a motherboard and instead opt for a lower-cost option. The ASRock Z390 Taichi Ultimate, which has been specifically developed for online gaming, is one of the best motherboard options for a processor like the i9 9900k.

The fact that it supports 10GB Ethernet adds to this, ensuring that you can stream and game without difficulty. To start, the Taichi Ultimate includes three PCIx16 slots, allowing you to install any GPU and sound card you desire. However, depending on your equipment, you may need to change and adapt the setup.

It’s also worth noting that the lower slot is close to the RTC battery, so be careful while inserting a card there. The Taichi Ultimate also has the capability of supporting up to six SATA connections. If you just have one M.2 slot, you’ll need to use the next one as well because it has a SATA port 3. The first and third slots, respectively, will accept two SATA associations, 0/1 and 4/5.
