    • If you need a Mini-ATX board, this is a fantastic choice
Size: B550M DS3H AC Style: B550M DS3H AC
Built 3 rigs using this motherboard. Not a single issue with those 3 rigs. BIOS updates can be sketchy if you want the latest image, but even without it will run just fine. For around the 100 mark, it's a fantastic mini-atx board and I would recommend to everyone. If you have space in your case for something larger, then yeah, go larger, cause Mini-atx will be feature short compared to larger offerings. ... show more

    • Awesome Affordable Motherboard
Size: B550M AORUS ELITE AX Style: B550M AORUS ELITE AX
This motherboard punches well above its weight. Built in Wi-Fi and Bluetooth work great if your drivers are up to date, something which is very easy to do using Gigabyte's software. I/O panel has all the options you would expect from a mordern motherboard. I have a pretty powerful mid-tier build (Ryzen 7 5800X, RX 7700XT, 3600MHz DDR4 RAM, 1Tb SSD) and I have yet to be bottlenecked by the motherboard. I would give 5 stars were it not for the lack of POST code LEDs, which is a big flaw. ... show more

    • Arrived DoA
Size: B550M DS3H AC Style: B550M DS3H AC
Gigabyte used to be among the best. The ran a basic power test on every single board while it was still on the line, just before packing, so you never got a DoA board from them. Now, roughly 1 in 50 Gigabyte boards is DoA. This was the only board on the market that met my specs otherwise I would have never considered. Stay away from ASUS, too—they'll make you pay to ship your board for warranty, pay to ship a new one back, and penalize you for the cost of the process so you end up paying half the price of your board to get a new one when they're the ones that messed up. For now, ASRock is the only manufacturer that doesn't leave you out to dry or with frequent DoAs. When I got this board, I had intended on doing the build right away. That did not happen; life intervened. By the time I realized there was a problem, I was already outside the return period, and just past the absurdly short warranty period. The board LEDs do no light up. Using a power tester in between the PSU and the 24-pin ATX power connector showed the PSU is supplying power with ideal specs, but the main board wasn't drawing power at all, and would not respond to power on. Another way to test, if you don't have the fancy equipment I do, is to connect your power to the main board, then with a cheap multimeter, test the PWR_LED pin on the front panel header to its ground pin (or any other ground pin) and you should get around 3 Volts. Mine was 0 V. ... show more
