Quick Buying Tips!

Before we proceed, this is what you should consider before buying a Motherboard for i9 9900K.

VRM Quality: VRM or Voltage Regulator Module is an electronic circuitry that supplies voltage to a chip. The higher the number of phases, the more stable and safe your CPU will be from overheating.

Atomic Clock Sync: A custom option from manufacturers which provides you with the ability to sync your PC’s clock speed with atomic clocks to ensure the maximum overclocking potential.

I/O: This is a port or ports on a motherboard through which users connect peripheral devices such as mice, keyboards and external drives. Make sure you have enough for yourself.

SLI/Crossfire Support: If you are planning multiple GPU setups then it might be worth looking into SLI or Crossfire support for your Motherboard. You need to make sure that the motherboard supports it and has room for you to add an additional GPU in order to do so. If not, then there is no point buying a good processor like i9 9900K only to find out that its useless with multiple GPUs.

Quality & Stability: You will need to invest in motherboards that are durable, stable and have better quality. Not every motherboard with the same chipset is made equal so you should do some extra research on it. A good idea would be checking reviews from websites or YouTube channels that specialize in Hardware reviews to see how they say about a particular motherboard that you are interested in purchasing.

Price: In the end, it all comes down to money. Not everyone can afford a $300 motherboard for just overclocking purposes so you might have to choose between buying a good motherboard or going for multiple GPUs.

So, without further ado, let’s get started with our Best Motherboards For i9 9900K!

Our Recommendation for Best Motherboards For i9 9900K in 2022

ASRock Z390 Phantom (Image credit: Amazon)

ASRock Z390 Phantom

Best Phantom Motherboard for i9 9900K

REASONS TO BUY

Supports 9th and 8th gen Intel Core

Pentium Gold

Celeron processors for LGA 1151 socket

Supports DDR4 4400+(OC) MHz

12 Power Phase Design

REASONS TO AVOID

No Wi-Fi, no Bluetooth

Price may be a little too high

ASRock has added a white edition of its flagship Phantom Gaming series. The new motherboard is based on the flagship line of 13th generation Core processors, Intel Z390 chipset and supports both 8th gen Core “Coffee Lake” processors as well as upcoming 9th Gen Core CPUs. This makes ASRock Z390 Phantom Gaming 9 one of the first motherboards to support both current-generation and next-generation platforms, which may increase user upgrade options with lower costs in future.

The motherboard is equipped with four PCIe Gen 3.0 x16 slots with steel reinforcements, which can be used in SLI/CrossFireX setups up to quad-GPUs; three of them are connected to the CPU, while the fourth uses an ASMedia PCIe controller. A 32 Gb/s M.2 slot for SSDs also shares space on the board’s right side (alongside SATA ports) and supports both Intel Optane Memory as well as RAID 0 configurations.

Another notable feature of Z390 Phantom Gaming 9 is its built-in wireless AC module, based on the Qualcomm Atheros QCA6174 controller providing 2×2 802.11ac Wi-Fi (up to 867 Mbps speed). It also comes with a 802.11ad link, which operates in the 60GHz frequency band and provides up to 4 Gbps speed.

This module supports Bluetooth 5.0 as well. The motherboard packs a total of six USB 3.1 Gen 2 ports, two on the rear panel (one Type-C), four through internal headers; also there are four USB 3.1 Gen 1 connectors and three USB 2.0/1.1 ports available for additional devices.

ASRock Z390 Phantom Gaming 9 comes with an integrated I/O shield with the same design as the one used in its predecessor Z370 Taichi, yet it doesn’t block some expansion slots’ space on mini-ITX boards, which was possible due to unusual placement of I/O connectors there causing problems with some cards – hopefully this won’t be the case here anymore either.

MSI MEG X570 ACE (Image credit: Amazon)

MSI MEG X570 ACE

Best Flagship Motherboard for i9 9900K

REASONS TO BUY

USB 3.1 Gen2 Type-C (10Gbps)

RGB Fusion headers

Front panel USB 3.1 Gen 2 Type-C

REASONS TO AVOID

None yet Testing Rig Case

The X570 ACE is the second beast in the MEG series and according to MSI, it’s an upgrade that will make your desk look like a battle station with its larger size and for good reason. It has more power connectors but doesn’t forget about USB 3.1 Gen2 Type-C either as we saw with the previous X470 board ( Click here for review ). For those who plan on putting together a Ryzen 3000 series PC with components such as dual GPUs or fast memory, you now have another choice of motherboards from MSI.

Unlike the X570 Gaming Pro Carbon AC that has a black+red color scheme with swappable covers, the MEG version is closer to their flagship gaming lineup with its black + yellow design. Underneath all those layers of plastic is a PCB that’s twice as thick and it even has metal reinforcements on certain spots for added strength and durability: The PCIe slots aren’t just flimsy pieces of metal like what we normally see on other motherboards.

Like most modern boards today, everything else outside of the CPU socket area can be found under various heatsinks or tucked away behind shrouds such as this one: There are eight power phases (8+2) at work underneath but you can also find an 8-pin EATX12V connector for additional power. According to MSI, this motherboard has passed their own 24-hour stress test with the highest level of quality control just like other boards in the MEG series.

Things are beginning to look interesting already but let’s go over some features before looking into specifications and performance: I/O ports are located at the bottom along with buttons to disable certain functions or even reset your whole system. Unlike most motherboards though, you’ll need a screwdriver since these don’t have detachable covers.

Gigabyte Z390 AORUS Pro (Image credit: Amazon)

Gigabyte Z390 AORUS Pro

Best Premium Motherboard for i9 9900K

REASONS TO BUY

3-way SLI M.2 card support

10 Gbps USB 3.1 Gen 2 Type-A

Intel Gigabit LAN controller

Thunderbolt 3 USB Type-C port

REASONS TO AVOID

No CPU power phases

Costly with not many features

Gigabyte’s Z390 AORUS Pro motherboard is a feature-packed board that should be considered by any Intel Coffee Lake user looking to upgrade to either the Z370 or Z390 chipset. If you’re among those who need as many USB ports as possible, this might just be your best bet for a full sized ATX board with six USB 3.1 Gen 1 (5 Gbps) Type-A ports and one reversible Type-C port coming from the back panel alone.

The Gigabyte Z390 AORUS Pro offers features usually found on high-end boards such as an Intel Gigabit LAN controller, two M.2 slots both capable of running at full speed using PCIe lanes, a Realtek ALC1220 audio codec and a three-way SLI+WiFi M.2 card slot allowing user to run two M.2 SSDs at full speed for output from the CPU as well as from the PCH.

In terms of overclocking features, Gigabyte have added both voltage check points and switchable dual BIOS chips that help keep users safe in case something goes wrong during the overclocking process or if one of the BIOS chips fail to work properly.  The board also supports a three-digit POST code display which will help you troubleshoot boot issues.

The Z390 AORUS Pro comes with everything an overclocker needs at the moment (except for CPU power phases) and is priced competitively in the $200 area, making it one of few boards available for this price that features both high-end features and enough performance to satisfy most users. If previous generations are anything to base our judgement on, we can expect to see this motherboard selling out fast after it’s released worldwide.

Asrock Z390 Phantom Gaming 9 (Image credit: Amazon)

Asrock Z390 Phantom Gaming 9

Best Gaming Motherboard for i9 9900K

REASONS TO BUY

Solidly built

Great overclocking options

Dual M.2 slots

REASONS TO AVOID

Limited availability of 4400MHz memory kits

The Phantom Gaming motherboards have been around for some time, but have always lagged behind the competition. This Z390 offering hopes to change that by embracing everything that makes an overclocking motherboard great. Welcoming high speed memory, power delivery tuned for the latest Intel Coffee Lake processors and of course a full gamut of overclocking options are just some of the options available on this impressive looking board. Add to this two M.2 slots, one supporting PCIe Gen 3 x4 and with four DIMM slots (two supporting memory speeds up to DDR4-4400) you can see where Asrock is aiming this motherboard; at gamers who want all the features in their system they could wish for at an affordable price point. 

There are a lot of boards around that support memory speeds over 4000MHz but the majority of them all come with either an extreme price tag or try and keep things simple by limiting overclocking options, not this one though. The Phantom Gaming 9 from Asrock is at first glance a board that has been designed for speed first and foremost then added a few extra bits as an afterthought, if at all. Let’s take a closer look and see just how well it performs on both stock settings and when overclocked.

As always, though, there are a few provisos. Memory kits capable of super-high speeds are expensive compared to their lower speed siblings. They’re also more power hungry and demand tighter quality control in order to run at full speed. For example, both Corsair and G.Skill offer 4266MHz memory on the basis that only their top-end Dominator Platinum kit will do that speed reliably – and even then under certain circumstances.

ASUS ROG Maximus XI Hero  is the new mainstream motherboard from ASUS that has replaced its previous generation Z370 boards. Replacing a product is never an easy task and when it comes to motherboards, there are several factors such as overclocking, aesthetics and overall stability that contribute to its success or failure in the market. Another aspect is the pricing of the board which needs to be competitive enough so that users don’t choose other options in order to save some bucks. 

ASUS ROG Maximus XI Hero has a subtler design which is a good move from ASUS, but the price will play a key role in its market positioning. The new ASUS board comes with upgraded VRM circuitry and better heat sinks to ensure maximum stability under prolonged periods of high loads. The automatic overclocking feature called 5-Way Optimization makes overclock as easy as pressing a button rather than spending time tweaking everything manually. In this review, we are going to take an in-depth look into the motherboard’s features and benchmark its performance with our i9 9900K processor that has been overclocked to 5 GHz across all cores using liquid cooling system.

ASUS ROG Maximus XI Hero comes with four DIMM slots supporting memory speeds of up to DDR4 4400 MHz . The board also has two M.2 slots which support both PCIe and SATA storage devices, but if you want to use a RAID array or any other hardware that requires more bandwidth then the second slot will be limited to SATA III speeds.

The motherboard’s rear panel includes a PS/2 connector for legacy peripherals such as mice and keyboards along with Wi-Fi antenna connectors used in conjunction with the 802.11AC AC Wave 2 Wi-Fi module included in the motherboard’s bundle. There is a single HDMI port, USB 3.1 Type A and Type C ports from the latest generation of connectivity standards.

Only single x16 PCI Express 3.0 connection

No M.2 slots with PCIe connectivity

The Asus ROG Maximus XI Gene Z390 is the company’s latest and most powerful Micro ATX (mATX) motherboard, based on the Intel Z390 chipset, which provides access to the 8th generation of Core CPUs (Coffee Lake), such as the Core i5-8600K or Core i7-8700K.

While previously it was not possible to incorporate high performing components into a PC case smaller than conventional Mid Tower, currently motherboards for mATX cases are already capable of housing powerful components such as the Core i7-8700K, 32 GB of DDR4 RAM and up to two powerful graphics cards in SLI or CrossFireX.

The Z390 chipset is similar to its predecessor in that it provides access to the same features and technologies: PCI Express 3.0 (although only in a single x16 lanes configuration), support for DDR4 4133 MHz memory modules, USB 3.1 Gen2 (10 Gbps) ports on the rear panel, M.2 SSDs with up to 32 Gbps bandwidth and Intel Optane Memory compatibility through U.2 or M.2 interfaces. However, the Z390 adds support for Intel’s Wireless-AC 9560 connectivity (while the Z370 supported Wireless-AC 8265) with up to 1.73 Gbps of bandwidth and Bluetooth 5 support.

Another notable feature of this chipset is its compatibility with Coffee Lake processors thanks to an adjustable power design that facilitates overclocking and overvolting and it also has a DIGI+ VRM voltage regulator module capable of reducing energy losses and increasing efficiency . For those who want to improve their PC audio we have included improvements such as ESS SABRE 9018Q2C DAC or SupremeFX S1220 codec which supports up to 24 bit / 192kHz playback through the rear panel jacks or by using optical S/PDIF. Of course, the use of an Op-AMP and dedicated headphone amplifier for high impedance headphones is still present.

Gigabyte Z390 AORUS MASTER

Best ATX Motherboard for i9 9900K

REASONS TO BUY

Budget Friendly Price

EASY OVERCLOCKING

SLI/CROSSFIRE SUPPORT

REASONS TO AVOID

NO DISPLAYPORT IN THE BACK I/O

Gigabyte is one of the brands which has always been closest to our heart, because they produce some of the highest quality products at competitive pricing. Their range of motherboards under Z390 chipset are built to be compatible with 8th and 9th generation Intel Core processors (Coffee Lake-S). We took a look at their top offering in the AORUS series – Gigabyte Z390 AORUS MASTER.

The first thing that pops into mind when someone mentions AORUS is their flashy color schemes, but it’s not what you will get on this motherboard. Instead, Gigabyte has gone for aluminium heatsink covers all across board (except on I/O shield), giving gamers a premium feel without compromising on stability.

The rear I/O panel houses four USB 3.1 Gen2 ports (one supports Type-C), six USB 3.1 Gen1 ports, three DisplayPorts, one HDMI 2.0b port, Gigabit Ethernet, 7.1 channel audio jack and two antenna connectors for the integrated Intel Wireless-AC 9560 solution supporting 802.11ac Wave2 + Bluetooth 5 connectivity.

Starting with the CPU power delivery system, there are 12 phases split into two groups of six phases each which are powered by International Rectifier PowIRstage controllers with IR3555 MOSFETs rated at 60A maximum load current with max temperature of 90°C. There is a thick heatsink over the MOSFETs covering both controller groups with a heatpipe to take care of thermal dissipation. The Z390 chipset heatsink, on the other hand is very small and doesn’t even cover all its components.

There are eight DDR4 DIMM slots supporting up to 128GB at speeds of 4133MHz+ in dual channel configuration. There are four PCI-E x16 Gen 3.0 slots out of which only one slot operates at full x16 speed while all others operate in two modes – either at full x8 speed or when both are used, they provide x4 bandwidth. In addition to this, there is also a 1x PCI-E slot present on the motherboard can be used for add-on card such as sound cards or network cards.

The most distinctive feature of this motherboard is that not only does it support 2-way SLI but also 3-way and 4-way SLI (with appropriate number of PCI-E slots for each setup). The power delivery system makes sure there is no bottleneck when multiple GPUs are used in the system. There is a U.2 port supported by an included expansion card which can be used for high speed SSDs like Intel’s Optane SSD 900P series with speeds up to 2600MB/s reads and 2000MB/s writes (though using NVMe drives in RAID isn’t supported). There are six SATA ports with four out of six having right angled connectors at the bottom, one USB 3.1 Gen 1 front panel header and two USB 2.0 headers for internal connectivity.

Frequently Asked Questions

Do all motherboards support i9 9900K?

That is a good question and we will answer it before we see the best motherboards for i9 9900K. i9 9900K has landed and like every other CPU, it needs a motherboard to connect with rest of the hardware in your system. All Intel CPUs are not created equal. Each CPU has different power requirement and only compatible motherboards can provide that to the CPU. There are some LGA 1151 socket motherboards which do not provide required power to the CPU. This results in the CPU working at its sub-optimal performance or even becoming unresponsive. We have listed down best motherboard for i9 9900k below. With these motherboards you will never need to worry about power delivery to your CPU ever.

Is the i9 9900K overkill?

For gamers and content creators, most of the time it is not worth upgrading your CPU unless you are doing something which requires high performance. While this is true with i3 8100 or even i5 8400, but if you spend over $500 on an Intel CPU, it will be foolish to go for anything less than 6 cores. The fact is that there are no games out in the market that can utilize more than 6 cores currently.

What Motherboard is best for Intel Core i9 9900K?

While motherboard specifications come down to personal preferences, we have picked motherboards which are known to overclock well. We pick Gigabyte Z390 AORUS MASTER for best motherboard for i9 9900k.

Why Gigabyte Z390 AORUS MASTER?

Gigabyte Z390 AORUS MASTER is one of the few boards that has 8 power phases. This ensures that your CPU never runs out of power no matter how much load you put on it. This board overclocks like a beast and with proper tweaking, you can push even higher than 5 GHz on this motherboard which is insane. We have tried to include motherboards which are not only good for overclock but also great choice aesthetically with easy cable management experience. If you want cheap motherboard for i9 9900K then there are other options available as well so let’s check them out too while we are here.

Is it worth upgrading to i9 9900K?

For most gamers, i5 8400 is a hard to beat choice and it will continue to remain so for at least next couple of years. Not only it has six cores which offers high performance even in games that do not use more than four cores but also offers great value for money. We got over 100 fps on GTA 5 and PUBG running on an i5 8400 with 16 GB memory and GTX 1070 so we don’t think we need anything more than this right now. If you are one of those people who is looking ahead, i9 9900K might be the best thing you can buy as long as you want enthusiast grade performance with few tradeoffs such as higher power consumption and heat generation (which is no big deal).

Intel Core i9 9900K vs Core i7 8700K: Is it Worth Upgrading?

If you already own a Core i7 8700K, we suggest to stay put and wait for the next big thing coming out from Intel which will probably be 9th gen core series HEDT CPUs. If you are planning to upgrade, the CPU that you should get is Core i9 9980XE or even better yet go with AMD RYZEN Threadripper 2990WX right now. These CPUs offer more value than an upgrade right now and performance difference between both platforms is huge so if you ever plan on going with X299 platform in future then we suggest getting 7960X or even better.

Is i9 9900K good for gaming?

While there is nothing wrong with i7 8700K, but you cannot call yourself an enthusiast until you own the 9900K. If you are buying new hardware, we would say go for Ryzen 7 2700X or even better yet Threadripper 2990WX if budget is not a constraint. AMD RYZEN offers great value for money and it scales well with multiple GPUs which has been one of its biggest advantage over Intel CPUs.
