Great motherboard from Gigabyte. Plenty of power for budget build or premium. Excellent customer service! Totally recommended.

good motherboard, works as intended, no Bios issues thus far. As with all itx motherboards it isn't the most cost effective unless you want an itx size build.

Really happy with this motherboard. In my opinion it's better value for money than the X570 variant, with little compromise on features. High quality audio and PCIE gen 4 compatible. I believe the USB header is more up-to-date too! Full marks to Gigabyte.

Got the Gigabyte B550I AORUS PRO AX ITX Motherboard and AMD Ryzen 5 3600XT for gaming build. Didn't even realise there was a promo which is a bonus! However the Gigabyte B550I AORUS PRO AX ITX Motherboard looks beautiful. Premium quality and the design is great. Works perfectly without any problems. Supports Q-Flash which allows BIOS update via USB port. Great for using latest Ryzen processors without the need of purchasing previous Ryzen processor. Motherboard is great for overclocking and the BIOS interface is nice and clean. Would highly recommend Gigabyte Motherboard or any Gigabyte products!

Perfect motherboard for small mini-itx cases. Fits perfectly for the NZXT H210 Mini ITX Tower case with all the necessary ports. Only lacking a front USB-C header.

Great motherboard with excellent compatibility, only slight drawback is the lack of a USB C header though this isn't an issue for me as my case does not feature USB C. Great value for money

Fantastic motherboard with great features. Very compact, solid, and also looks very good. In my opinion this is one of the best ITX motherboards for AMD on the market right now.
