This is a 24.4 x 24.4 cm, mATX-factor product equipped with a B550 chipset, and it offers such features as 6+4-phase power design (Dr MOS) and 1x Gigabit ethernet (the ATX version has 2.5 Gbps). Price... Review: Biostar Racing B550 GTQ
Biostar is really really cheap those day, the B450 version of this board is at 40 Euro... in A320 budget range. As you said and as this B550, you can't expect latest technology or build around the chipset, neither a bios update each week... but you have a good chipset at exeptional low price and major bios update. You can OC too (at your own risk but you can )... it's acceptable at that price.
If I remember correctly from some webcharts, both the GTA (ATX) and the GTQ have the same power phase, meaning the only real big difference is the form factor and the 2.5Gbs ethernet. Kind of a bummer so many X570 and B550 boards don't have the faster ethernet option. I was browsing for a new motherboard since we will be stuck with B550 and x570 to run Ryzen 5000 (yeah yeah, b450 and x470 run it too but hey, if I waited this much might as well just grab a newer board), but I guess I'll wait around for reviews and see which ones can handle those CPU's Oh, one thing I was checking on the review (https://www.guru3d.com/articles-pages/biostar-racing-b550-gtq-review,8.html) below the summary, it reads "Gigabyte B550 Vision D did very decent here, with its ALC 1150 audio codec." I mean, the codec is right, but is the result from the Biostar or from the Gigabyte review?
Thanks. That VRM is sub par. This would be fine for an 8 core build you don't plan to OC. You might get away with a stock 12 core but I couldn't plan on 16 core or any OCing. Glad you are paying attention to VRM's the more vendors that do this the less likely vendors will skimp on them like has been done here.
