MSI MEG GODLIKE Z390

MSI Meg Godlike are flagship motherboards and might be the most-featured packed in this entire list, and that’s the reason I’ve selected this gaming beast. This motherboard can easily overclock Intel i9 9900K to its new limits as it has 18 Phase Power Design VRM, which gives excellent performance. You can install memory up to 128Gb and can overclock it up to 4400Mhz. Looks-wise most of the area on the Motherboard is covered by heatsinks and has black coloured PCB with some grey touch on it.

MSI MEG GODLIKE Z390 has six SATA6 slots and three M.2 slots for memory and Wi-Fi modules. It has one USB 3.1 Gen2 Type-C port, three USB 3.2 Gen2 Type-A ports, one USB 3.1 Gen1 Type-A port, and some USB 2.0 ports on rear I/O panel. This motherboard is using some of the most expensive audio and network controllers from MSI and has built-in Wi-Fi and RGB lights. There are four PCIe x16 slots, and you can install multiple AMD and Nvidia graphics card on this motherboard.

That’s all about the specification of this motherboard and now heads toward the cons we have noticed in it. No doubt, this motherboard got amazing features set, but still, this one is costly for any Intel Coffee Lake processor. The storage performance on this motherboard can be much better, but I’m not sure if most of you notice it. Also, for this price, motherboards come with 10GBPS Ethernet port, but this one lacks, and that’s all about it.

Best Micro ATX Motherboard for Ryzen i9 9900K – ASUS ROG Maximus XI Gene Z390

ASUS ROG Maximus XI Gene Z390

There we got another Maximus motherboard, and there is some performance difference, and this one has different aesthetics from the above mentioned. This motherboard is micro-ATX and can be fit into any mid-tower chassis. It has a 12 Phase power Design VRM and supports most of the Intel Coffee Lake processors out of the box and gives high overclocking power. For memory, this motherboard has two RAM DIMMs, and you can install maximum memory up to 64GB and can overclock it up to 4000Mhz.

As I’ve said earlier, this is a Micro ATX motherboard, so of course, it lacks some features that other ATX motherboards offer. First of all, there is only a PCIe x16 slot and one PCIe x4 slot, and this motherboard doesn’t support multiple graphics cards in any Way. This motherboard has four SATA6 slots and has two M.2 modules support. For connectivity, it has three USB .1 Gen1 Type-A, one USB .1 Gen1 Type-C, eight USB .1 Gen1, and two USB 2.0 ports and has Wi-Fi support.

There is something you must need to know about this motherboard before considering it for you, i9 9900k. This motherboard doesn’t support multiple graphics cards in any way. Also, there are only two RAM DIMMs, which are not enough for any enthusiast build. There is no legacy SATA m.2 support in this motherboard. Enabling the CPU storage can drop the PCIe x16 to x8 mode.

This motherboard is suitable for any mid-tower build, but if you are looking for something sturdy, I would not recommend it. There are several choices on this list, and you can go with anyone if you want the best price for features and performance. If you are looking for something smaller, we have another option listed below.

Pros

  • Have excellent VRM.
  • Best for micro-ATX builds.

Cons

  • No Legacy SATA M.2.
  • Only two memory slots.
  • No multiple GPU support.

Best Mini ITX Motherboard for Ryzen i9 9900K – ASUS ROG Strix Z390-I Gaming

ASUS ROG Strix Z390-I Gaming

If you are looking for aesthetics and performance, ASUS Strix motherboards are best for you and also are quite cheaper than the Maximum series. This motherboard is suitable for ITX builds, has 12 Phase power design VRM, supports every Intel Coffee Lake processors, and fits best for our i9 9900K. If you are building a compact or small form factor PC, this motherboard is for you. It has two RAM DIMMs and supports memory up to 64Gb and can overclock up to 4000Mhz+.

Features wise, this motherboard has everything a mini-ITX motherboard offers, but for an ATX build, this one is not recommended. It has only one PCIe x16 slot and doesn’t support multiple graphics cards or any expansion card. For connectivity, it has excellent options, including several USB 3.1 Gen1 ports (Type-A and Type-C) and also has USB 2.0 ports. It has four SATA6 slots and two M.2 Socket 3 for NVMe SSDs. This motherboard also has built-In Wi-Fi, which makes it best for this price point.

There are some cons of this motherboard and check them out before considering this for your build. The ASUS Aura RGB lights have compatibility issues, and there are some older motherboards too, which have that issue. Also, the M.2 slots run just right on the graphics card, known as the warm-side. It looks awkward to use the front panel headers on this motherboard, and that’s all about this motherboard.

This motherboard is best for compact and small form factor builds, but if you want performance and aesthetics, I would recommend you to get an ATX motherboard and full tower case. This processor is powerful enough, and you can get the full performance out of it with some features enriched motherboard.

Pros

  • Have PCI Steel Armor.
  • Recommended for SFF builds.
  • Support high OC memory modules.

Cons

  • M.2 runs on warn side.
  • ASUS Aura RGB lights issues.
  • No SLI and Crossfire support.

Conclusion

These all motherboards are best for Intel Core i9 9900k, and I would recommend you to get anything according to your budget from this list. If you want something affordable and features enriched, go with Gigabyte Z390 Aorus Pro, while if you want something sturdy and expensive, there is MSI MEG GODLIKE Z390. But it’s not good to get a $600-$700 motherboards for this processor, save that money for other components like graphics cards, or get dual GPUs.
