| Great Overclock Potential | |
| Affordable |
First up, we have ASROCK Z390 Phantom Gaming ITX motherboard. This motherboard comes in mini-ITX form factor and has LGA1151 Socket. Having LGA1151 socket means, you can have both intel 8th and 9th gen processor. It has 2 ram/memory slots and supports a maximum of DDR4 64GB ram, with a maximum clock speed of 4500 MHz+
In storage options, we have 4 SATA 3.0 and 2 M.2 sockets available. This motherboard has only 1 expansion slot(PCIe x16), but it does have an additional vertical M.2 socket with Wifi/BT pre-installed. Z390 Phantom Gaming ITX also has 2 LED Headers to add some RGB flavor to your brand new gaming build. These RGB can be controlled with ASRock software.
Recent Buyer Feedback
More than 70% of the buyers have given this motherboard a solid 5-star rating. Many of the buyers are impressed with its build quality and good layout. Fact that this mini-ITX mobo has 2 M.2 sockets is very well received as well. Many buyers also pointed out its great overclocking potential. According to a buyer, this motherboard had no difficulty overclocking the i5 9600k processor to 5.0Ghz with Air Cooler.
Any Downsides?
There are not many negative reviews about this motherboard. A few buyers said they were having trouble installing drivers for built-in xHCI Compliant Host Controller.
Our thoughts
Overall build quality and performance of this motherboard is really stable. The board looks amazing with its elegant looks. Not many mini-ITX motherboards offer M.2 slots and Thunderbolt 3 port. It supports not one but 2 M.2 sockets and a rear Thunderbolt 3 Type-C port. It’s also competitively priced which makes it “THE BEST mini-ITX motherboard”.
The only complaints I have seen so far are related to built-in xHCI Compliant Host Controller drivers.

How to choose the best motherboard for i9 9900k?
You can see a list of best intel i9 9900k compatible motherboards below but before that, there are a few things every gamer needs to keep in mind about i9 9900k motherboard compatibility. Some of them are:
Processor Socket;
i9 9900k supports LGA1151 socket. You need to make sure the motherboard you choose has an LGA1151 socket. But don’t worry, all the motherboards on this list have LGA1151 socket 🙂
Form Factor;
Motherboards come in 3 different form factors: ATX, Micro ATX & Mini ATX. ATX being the biggest and mini-ITX being the smallest motherboard. Bigger motherboards have more connectivity ports, more expansion slots, and more ram slots but they do cost more than their smaller counterparts.
Expandability;
Each motherboard on this list has unique features. They come in different sizes. Bigger motherboards have more connectivity ports, more expansion slots, and more ram slots. If you want to have more ram then you need to consider bigger motherboards with 4 DIMM slots. Similarly, if you want more storage expansion options, then you need to buy a motherboard with more M.2 ports.
Having more slots/ports means, you have more upgrade potential with bigger (ATX) motherboards. But ATX motherboards cost more than smaller (Micro ATX, Mini-ITX) motherboards. You can go with smaller boards if you’re on a budget build.
Connectivity;
You need fast Ethernet and Wifi adapters for the best gaming experience. Bluetooth connectivity is a PLUS.
Overclock Potential;
When buying a “K” series processor like i9 9900k, you need to make sure the motherboard you choose has good quality VRM and heatsinks. This is very important if you want to overclock your i9 9900k processor to stable 5.0 GHz or more. Good bios and software are very important as well for an easier and safer overclocking experience.
