Some nice features of this board are RGB LEDs, steel armor on PCI Express slots and DIMM, ESD guards, etc. X570-I’s Wi-Fi is capable of supporting both Ryzen 2nd and 3rd generation processors which also includes SATA ports and PCIe 4.0. The pair of DIMM supports 64GB of DDR4 RAM and the overclocking speed is up to a fast DDR4 4400MHz. The quality of this board is super as well. It is the cheapest x570 ryzen 3900x motherboard with dual NVme and decent VRMs.

The direct 8 phases Digital VRM solution delivers a decent power and the multiple temperature sensors does a great job while the heatsink and cooling fan system reduces the warmness. The fan headers have the feature “Fan STOP†just like Gigabyte X570 AORUS Elite. It is probably the best mini ITX motherboard Ryzen 9 3900X here.

Key Features & Downsides

Key Features: The Gigabyte X570-I Aorus Pro Wi-Fi comes with 2 x DDR4 DIMM memory sockets supporting up to 64 GB and 5300 (O.C.) MHz of memory clock speed. It features a 1 x PCI Express 4.0 x16 slot running at x16 mode, 2 x M.2 sockets, 4 x SATA 6Gb/s connectors, and solid 8 phase digital VRMs. It also features 2 x USB 3.2 Gen 2 Type-A & C, 2 x USB 3.2 Gen 1, 2 x USB 2.0/1.1 ports, and 2 x fan header.

Downsides: Though the heatsinks and fan headers reduce the temperature with their utmost quality, two fan headers are still not enough. Also, the 1st M.2 slot for the board chipset is right above the heatsink.

Final Thoughts

Mini ITX boards are capable of handling anything from an HTPC to a full gaming rig. Gigabyte X570-I is undoubtedly a good choice as a Mini ITX board as there aren’t many boards with the highest of six USB ports, though it is a small factor.
