Choosing the Best Motherboard

Intel Core i9-12900K is one of the finest gaming processors and the priciest of the 12th-generation processors. It is a processor with sixteen cores, so choosing a motherboard for this processor is not exactly an easy task. 

That is why we have created this buying guide for those considering buying a powerful motherboard for the i9 12900K. Following are some major points that must be considered while purchasing a motherboard for this mighty processor.

Pricing of Motherboard

The first and foremost thing you do is to check your budget. Once you estimate your budget, you can go further in selecting a motherboard. Usually, low-end motherboards cost around 150 bucks, while flagship motherboards cost more than 400 bucks these days. 

A good approach will be to consider the value motherboards, which come at around the $250 range but provide most of the features of flagship motherboards. However, the design of such motherboards is not good as the flagship ones.

Looks & Aesthetics

Another important thing to consider is the motherboard’s overall theme and design. Choose a color theme based on the color of your PC case and other components, and then you can further narrow down your search. 

Mainly, motherboards come in a black, white, or grey color. Most manufacturers cover these color themes in their motherboard models, so you won’t have to leave your favorite motherboard manufacturer just because of a color theme issue.

Voltage Regulators Module

Since we are talking about a motherboard for i9 12900K, you must buy a motherboard with a powerful VRM. VRM, aka Voltage Regulator Module, is responsible for providing power to the processor and memory. As i9 12900K is a power-hungry processor, if you couple this processor with a motherboard with weak VRM, you will have a lot of issues, especially in the case of overclocking. 

Thankfully, most Z690 motherboards come with a powerful VRM, although make sure that you check it before finalizing your selection.

Upgradeability Options

A great thing about the Z690 motherboards is that they provide many future-proof features, where the DDR5 RAM and PCI-E 5.0 slot are the most prominent. Unfortunately, not all the Z690 motherboards come with these features, and if you buy a motherboard without these features, you may have to change your motherboard shortly due to the added benefit of these features. 

Therefore, buying a motherboard that supports these features will be better, so you don’t have to upgrade the motherboard later.

Connectivity Ports

One of the basic use of a motherboard is to provide connectivity, whether with USB ports, LAN ports, audio ports, WiFi, or whatever.

Usually, low-end motherboards tend to cheap out on ports and slots, so you should ensure that the motherboard you are buying provides enough ports and slots that cover your daily usage.

If you compare it with other Z690 motherboards that offer similar features, you will find that its price is quite justified.

In our best B550 motherboard review, we’ve discussed the same price increase with these motherboards. There is a lot of changes in this motherboard from the previous generation other than the DDR5 memory and PCI-E 5.0 slots. 

There are five M.2 slots, better overclocking performance, better audio chipset, better networking features, and much more. The motherboard comes with an 18-phase VRM, while the previous generation offered 14 phases, and MOSFETs have improved from 70A to 90A to overclock the latest Alder Lake processors.

This motherboard has every premium feature a gamer needs, but the high price is the only problem, and if it costs a bit less, it will be the best gaming motherboard . 

This motherboard supports 128 GB DDR5 memory with up to 6400 MHz overclock support. There is one PCIe 5.0 M.2 slot on this motherboard and two PCIe 4.0 slots with a dedicated heat spreader. 

Two additional PCIe 4.0 M.2 drives can also be installed on the motherboard using the bundled Hyper ROG M.2 card. 

There are eight layers on the PCB, which help the motherboard against humidity. There are three ARGB headers, one RGB header, and eight PWN fan headers on the motherboard. 

The controllers on this motherboard are also expensive; the Ethernet is controlled with Intel I-225V, and there is Intel AX210 Wi-Fi 6E for integrated Wi-Fi. Realtek ALC4080 is used for enhanced audio, and all these features greatly affect the price of the motherboard.

The rear side of the motherboard has integrated I/O with a black background and white labels which makes it very easy to read. A BIOS Flash and CLEAR CMOS button along with twelve USB ports are notable at the rear. 

With all these features, I would recommend it as the best motherboard for i9 12900K. However, if you are thinking it’s expensive we’ve got some budget-friendly options too like the MSI Z690-PRO costing only $200 and is good for budget users.


The Pros:

  • Very affordable price.

ASRock TAICHI series is the flagship series by the company, and if you don’t know, the word “TAICHI” means “the philosophy of absolute potential”. For five hundred bucks, this is one of the best motherboards that provides lots of features, great power delivery, and excellent connectivity options. 

The ASRock product stack includes around thirteen different motherboards, including all form factors, and covers all types of audiences, but as we are looking for the best motherboard for i9 12900K, we’ve picked this option.

When you compare this motherboard with Z590 TAICHI, there are few improvements apart from the appearance, where power delivery is the most notable. Like the previous generation motherboard, there are two Thunderbolt USB Type-C ports (40 Gbps), Killer network and audio controllers, three M.2 slots, and a robust voltage regulator module. 

The 20-phase power delivery comes in a 19+1 configuration, and there are 105A MOSFETs for Vcore, which will give you exceptional performance for Intel Core i9 12900K. The motherboard comes in a dark-colored theme and suits most of the RGB builds as it has a black-colored PCB with black heatsinks. 

There is RGB lighting on the chipset heatsink and the I/O cover with TAICHI branding. Most of the motherboard is covered with heatsinks, especially the M.2 slots and the VRM. The upper part has four memory slots which allow you to install 128 GB DDR5 memory with a maximum memory clock support of 6400 MHz.

ASRock Z690 TAICHI D5 is excellent in all aspects, but the biggest drawback I’ve seen in it is the low number of USB ports at the rear. There are six USB Type-A ports, while there is an add-in-card that you can install to get two more USB Type-A ports, we were expecting more USB ports at the rear I/O. 

At the same time, there are only three M.2 slots on this motherboard, while we’ve reviewed a few motherboards for Alder Lake before, where they were four or even more slots.

We’ve discussed a few drawbacks of this motherboard, but the most important factor is its high price, so it will be much better if it is available at a discount. 

The TAICHI X570 and other old-generation motherboards from this series come with Torx screws which are a headache for most users but not anymore with this one. Overall, I would say it’s the best gaming motherboard for i9 12900K if you are not worried about the budget.


MSI knows all about the versatile range of PC builders that exist in the PC community such as the Budget builders, the mid-rangers, and the enthusiast class. Over the years, after excessive research and feedback, MSI has been catering to all the classes of PC builders from entry to the top end.

The MSI MAG B660M MORTAR DDR4 is a Price to performance product that can be used to power a PC containing a high-end processor as the Core i9 12900K. But it’s a mid-range product so you will have to ease off the Overclocking, but that doesn’t mean it lacks in the features department or can’t run the processor at all.

The MSI MAG B660M MORTAR DDR4 comes with a 12+1+1 Duet Rail Power system which means that it can handle multi-core processors just fine and combined with the Core Boost tech, the processor will have an uninterrupted and stable power supply so that you don’t feel any difference in performance. It comes with an optimal thermal solution that will make sure that the temps stay as low as possible even under tweaked conditions, it comes with an extended heatsink design, M.2 shield Frozr tech, Frozr AI Cooling, and its ready for an AIO pump as well.

The 4 DIMM slots on the board can host 128 GB of DDR4 RAM which can be overclocked to 4800 MHz with the XMP mode on, there is also a DDR5 variant of the board which can OC the DDR5 RAM up to 6200 MHz, although there is a small price difference between them and there is no difference of features between the two variants.

Just because it’s a budget offering doesn’t mean that it lacks in the features department as it comes with features like PCIe 5.0 steel armor slots, 2.5G LAN, dual M.2 gen 4 slots, USB 3.2 Gen 2x2 ports, Audio Boost, and AMD Crossfire capability making it quite feature rich.

The board is a mid-range offering and while it doesn’t look like a high-end board it doesn’t look cheap either. While the board comes with RGB headers it doesn’t come with a software utility which means that you will have to manually set a color scheme that you enjoy. Nonetheless, in the performance department, it won’t let you down and make you feel like you are bottlenecking and thermal throttling because of this board, making it a solid choice for building a PC that performs at a high level.


Gigabyte has cemented its place in the market by dishing out high-quality products that gamers regularly choose to build their PC with.

The RGB Fusion 2.0 gives you the choice of setting a color scheme for your PC that is visually pleasing to look at. Overall, it comes packed with features and it’s the favored choice of motherboard for overclockers and PC tweakers who want to tinker with the flagship processor by Intel the Core i9 12900K.


How to Pick Best Motherboard for i9 12900K

AMD gave Intel a hard time with their Ryzen 5000-series processors, but the Blue team made a great comeback with 12th-generation Core i-series processors. Intel Core i9-12900K is the finest processor of the bunch and comes with eight performance cores and eight efficiency cores. It is a power-hungry processor with a base TDP of 125 watts but can consume as much as ~240 watts with turbo clock rates.

Now, when it comes buying the best motherboard for i9 12900K, you will have to look at lots of things. That is why we have made this guide for those looking for a suitable motherboard for their processor.

Chipset Selection

The main chipset for 12th-generation processors is the Z690 chipset. Even though there are other chipsets too, like the H670, B660, or H610, for a high-end processor like Intel Core i9-12900K, most people would opt for the Z690 chipset. 

The Z690 chipset motherboard is the latest flagship chipset for Core i-series processors; and comes with many new technologies and features. The most notable features of this chipset are DDR5 RAM and PCI-E 5.0, although not all Z690 motherboards come with these features. As for the other 600-series chipset, Intel’s decisions stayed the same as the 500-series chipsets. The H670 and B660 motherboard do allow memory overclocking, but unfortunately, the processor can only be overclocked with a Z-series chipset, i.e. Z690. 

The H610 is the cheapest chipset for the current generation of Core i-series processors, but it comes with a lot fewer features, and even memory overclocking is not supported here. 

DDR4 vs DDR5 Memory?

It is true that DDR5 RAM is much faster in theory than DDR4 memory kits, with motherboards supporting up to 6600 MHz, which is astoundingly fast for memory. However, the difference in real-world performance is not much. It highly depends on the software application you are using. 

On average, there is roughly a 5 to 10% improvement in the performance of an average DDR5 memory kit compared to an average DDR4 memory kit. Overall, if you don’t care about the budget at all, the DDR5 memory is a no-brainer. 

PCI-E 4.0 vs PCI-E 5.0 Slots

Unlike the DDR4 vs DDR5 RAM, the case is somewhat different when we compare PCI-E 4.0 and PCI-E 5.0. Theoretically, there is a 100% improvement with PCI-E 5.0, as it offers a raw bit rate of 32 GT/s, compared to 16GT/s with PCI-E 4.0. 

However, as for usability, there is no computer hardware, as of now, that can saturate the PCI-E 4.0, especially the X16 slot. So, PCI-E 5.0 is good for future-proofing, but there is little advantage over PCI-E 4.0 with current-generation SSDs and graphics cards.

Conclusion

Now that you have gone through the list of motherboards you can get for your Core i9 12900K, the motherboard choice is much easier. I have tried to include all the best options from all budget ranges.

However, if things are still unclear, I have some insight that will help you choose a motherboard for your PC. If you want the absolute best of the best, then you should go for the ASUS ROG Strix Z690-E Gaming, as it contains all the necessary features and more that will help you draw the maximum performance out of your hardware. It will give you the ultimate premium experience that a PC enthusiast desires and deserves.

Although you can never go wrong with any motherboard, provided it has all the features necessary for your use case, it is future-proof, compatible with different technologies, and provides value for money.

Also, you don’t need to jump the bandwagon of buying every new piece of hardware that comes out as it might not fit your needs, so choose wisely and decide accordingly. Let this list be your guide in choosing a suitable motherboard that fits the criteria that comes with your PC’s use case (content creation or gaming).
