There are only a handful of mini-ITX X570 motherboards available for the Ryzen 9 3900X, there are not many motherboards to choose from, but with that said the Gigabyte X570 I Aorus Pro WiFi is the most promising ITX option for building with the 3900X. The motherboard is equipped with a lot of features such as black PCB, heatsink, PCIe slots, and many more.

It comes with two DDR4 memory slots that can support a storage capacity of up to 64 GB. The motherboard has a 14 (12+2) phase VRM that is controlled by the Infineon IR35201 8 phase controller that produces power in the 6+2 form.

The motherboard also has one Intel I211 AT Gigabit LAN and Intel Wi-Fi 6 so that you won’t have to be concerned about the network connectivity while gaming. All the Aorus series of motherboards have RGB Fusion 2.0 that is far better than the typical LED.  

The uppermost part of the motherboard has 3 fan headers (that is located at the right location of the motherboard), 2 CPU headers, and a system fan. 

The motherboard also has full PCIe structures like the PCIe slots as well as the PCIe 4.0 M.2 connectors that guarantee the proper performance of the motherboard.

To make it more durable the GIGABYTE provides a thermal solution for M.2 SSD devices. The thermal guard prevents throttling and bottlenecks from high-speed M.2 SSDs as it helps to dissipate heat before it interferes with your gaming.

You will also love the audio performance of the motherboard thanks to the Realtek ALC 1220 VB HD audio codec. For connectivity, you get USB 3.1 Gen 2 Type-A and Type-C ports and typical USB e.1 Gen 1 Type-A ports.

The price at which the X570 Aorus is available there is no other competing motherboards in the same price range that can claim of having numerous fan headers as it has. Even the expensive motherboards don’t have so many fan headers. 

  • Has a storage capacity of 64GB.
  • The M.2 thermal guard prevents the bottlenecks and throttling from M.2 SSDs.
  • The USB Type-C header makes it easier to connect a USB 3.2 Gen2 drive
