Biostar am4 mini ITX motherboard

After a steady stream of ATX and Micro-ATX form factor motherboard launches by various manufacturers, Biostar releases the very first Mini ITX AM4 motherboards for the AMD Ryzen series of processors.

Ever since the Ryzen launch in March, people have been anxiously awaiting a Mini ITX release. After a long wait, their prayers have been answered by Biostar, with the release of 2 motherboards in this form factor.

What is Mini-ITX?

This form factor is popular among PC builders who want smaller machines, without compromising on the hardware they can pack within. Even smaller form factors such as the Nano-ITX, the Pico-ITX, and the Mobile-ITX also exist. However, they aren’t used for traditional PC builds, instead, providing a platform for smaller devices such as Set Top Boxes, DVRs, Media Centers, etc.

The Brand-New Mini-ITX AM4 Motherboards

Biostar built these motherboards around the 2 most popular AMD chipsets in the market — the BIOSTAR RACING X370GTN featuring the X370 enthusiast chipset and the BIOSTAR RACING B350GTN housing the mainstream B350 chipset. However, the other specifications of both the motherboards are identical.

This has to be the cheapest X370 motherboard on the market currently. However, since the expansion slots on it are limited to only one, the X370 chipset cannot utilize the extra headroom it gets for SLI™ and multi-GPU support. Moreover, the number of I/O ports are exactly the same as its B350 variant as well.

Suggested Retail Price: $129

With a $20 lower price, this compact motherboard features the same technical specifications as its X370 counterpart, making it an ideal purchase for those who aren’t really bothered with the chipset. Moreover, since the AMD B350 chipset does allow overclocking, your Ryzen CPUs can be pushed as far as you like on these boards just as well. However, finer details and build quality of the motherboard might differ, but this can only be confirmed once reviews start appearing on the internet.

Suggested Retail Price: $109

Additional Features

All the features boasted by the Biostar Racing™ series of motherboards are present on these new Mini ITX AM4 motherboards as well. A few are:


VIVID LED DJ – Control your motherboard LEDs with the Biostar Vivid LED DJ utility. Options to play around with special effects like music-reactive LED animation are present as well.

5050 LED Fun Zone logo

5050 LED Fun Zone – The LED Fun Zone provides two additional 5050 LED headers for enthusiasts to power any further lighting in/on their gaming rigs.

FLY.NET logo

FLY.NET – Advertised to provide a smooth, lag-free multiplayer gaming experience, this motherboard uses the Dragon LAN hardware and combines it with the FLY.NET bandwidth management software. The jury is still out on whether this will have any real-world performance improvement in multiplayer titles.

Detailed Specs

Worth It?

Considering the fact that these two motherboards are the first Mini ITX AM4 motherboards for AMD Ryzen, the Biostar Racing B350GTN and X370GTN will be a boon for those who cannot wait to get started on their build.

However, if you are fine with waiting for options, the next couple of months should see more AM4 mini ITX motherboard launches from other manufacturers.
