  • RGB goodness
  • Very compact
  • Powerful RAM overclocking
  • Competitively priced for its offering

Cons

  • No m.2 slots

ASRock Fatal1ty X470 Gaming-ITX

ASRock has risen to recognition with its motherboards, and their Fatal1ty X470 is our second favorite high-end mini-ITX motherboard for AMD builds. Packing the X470 chipset and the AM4 socket, this motherboard comes with its own RGB system integrated into it.

It features DDR4 RAM compatibility up to 32GB that can be overclocked to more than 3466 MHz. The ASRock Fatal1ty X470 features 2 USB 3.1 Gen2 ports, 4 USB 3.1 Gen1 ports (2 front and 2 rear), and 4 USB 2.0 ports.

You also get Intel 2T2R Dual band WiFi and the package comes with a customized antenna. We also love that it has support for an m.2 SSD (slot at the back of the board), so you can install the most powerful NVMe SSDs out there for ultra fast read/write speeds.

  • Integrated WiFi
  • Plenty of fan headers

Cons

  • Lacks in advanced features

ASRock Fatal1ty AB350 Gaming ITX

The more affordable option for AMD builds is the ASRock Fatal1ty AB350. This mini-ITX motherboard by ASRock utilizes the less powerful AB350 chipset instead to power AM4 Ryzen CPUs.

You’re still getting plenty from this motherboard though, including a whopping 6 USB 3.1 ports, including a Type-C. However, all these ports are Gen1, not Gen2.

Two DDR4 DIMM slots allow you to install up to 32 gigs of RAM that can be overclocked to more than 3466 MHz. Additionally, you also get an ultra m.2 PCIe slot at the back to install a powerful m.2 NVMe SSD for the best read/write speeds technology can currently offer.

Given the price, it’s a great little offering, though we’d still recommend individuals to save up $25-30 more and buy the X470 version reviewed above instead. Still, if you prefer using the money you save with this for other parts of your build, then this is a solid option where sacrifices are only a few and far.

Pros

  • Packed with all essential connections
  • PCIe m.2 slot
  • Competitively priced for its offering

Cons

  • May require BIOS update for Ryzen 2000 series
  • Lacks Gen2 USB 3.0 ports

Buyer’s Guide

    The debate of which company is making better processors has been over for a while now. Both go neck and neck in their performance and appeal, but each caters to a specific computing niche more than another.

    Intel still remains the processor brand of choice for gamers as their Core i5, i7, and i9 processors offer the highest clock speeds and, concomitantly, the best overall performance. However, this isn’t to say AMD’s second generation of Ryzen CPUs are bad at gaming – they’re still a fantastic choice for anyone, especially considering how affordable they are.

    When it comes to processor intensive tasks requiring multiple cores (video editing, software development, rendering, and more), AMD’s Ryzen reigns supreme. They have Intel beat in these computing niches with their higher end processes (Ryzen 2500 and onward).

    Regardless of which you choose, the brand and model of your mini-ITX motherboard will be directly based on the processor choice.

    The mini ITX form factor simply doesn’t have enough space to offer more than two DIMMs for your RAM. This, along with the lack of multiple GPU options, are the two biggest limiting factors of the mini ITX form factor.

    Regardless, you can still build a powerful computer with a mini-ITX motherboard. All the motherboards we’ve reviewed for Intel and AMD have at least 32GB of RAM available over the two DIMMs, and all of them are dual channel memory capable for better synchronization.

    The Asus ROG Strix Z390-I is the only mini-ITX motherboard that supports more than 32GB RAM, but it also costs a lot more than any of the others. Nevertheless, 32GB RAM is more than sufficient for all but the most intensive computational tasks out there.

    You’re buying a mini ITX for two reasons: affordability and size. The latter is also dependent on your case. You can fit mini-ITX motherboards in many full ATX cases, but you’re defeating the purpose of choosing such a small form factor in the first place.

    It is thus recommended to go for a micro-ATX case or a dedicated mini ITX PC case if you’re buying a mini-ITX motherboard. For gaming and other intensive tasks, we recommend a micro-ATX case that has space for additional fans, a CPU cooler, and good cable management.

    If you’re seeking a more portable rig, then a dedicated mini ITX PC case is the way to go.

    Why go for the mini ITX form factor?
    In addition to offering the most powerful chipsets for Intel and AMD at a more affordable value, the mini ITX form factor also provides users the chance to create a more compact rig. This is usually preferred by gamers who take their rigs to events and those who have little space on their desks.

    Can you build a powerful gaming PC with a mini-ITX motherboard?
    Absolutely. A powerful Core i7 processor can fit in any Asus ROG Z370 or Z390 mini-ITX motherboard, and you can combine it with 32GB RAM, an m.2 NVMe SSD, a great micro-ATX or mini-ITX case, an Nvidia GTX 1080, and some cooling solutions to create a complete beast of a system.

    Are ASRock and Asus the same company?
    ASRock started off as a spin-off of Asus, but since July 2010 they have been owned by Pegatron, which is completely independent of Asus. In fact, Pegatron is a competitor of Asus.
