I really wanted this mobo to be liked. The RGB is good and the price is great. I currently have an Asus Rog Strix X470 F mobile phone. I decided to upgrade my computer with a 3800X and a Sapphire Nitro+ 5700xt and I wanted to use the 4 x 3200MHz TridentZ 8GB memory modules that I currently own. With the extra pieces I will have I thought it would be a good idea to put together a playset for my stepdaughter. Well, things didn't quite go as planned. I installed my 2700X and rx590 in addition to the 2 3200mhz ram dimms I bought for them on this mobo. Everything booted up and I was able to overclock the RAM. I encountered a problem as soon as I started playing it. I used to be able to run Witcher 3 very smoothly on my X470-F at Ultra settings at 1080p with my rx590. Now there was a visible lag. Frames stutter for no apparent reason. I lowered the resolution and detail settings but to no avail. This suggests that the problem is not in the graphics card. I've updated every driver I can think of and nothing has improved performance. Then, on a whim, I opened up Ryzen Master and saw that my CPU was drawing so much power (2700x is 105W) that it was idling between 97% and 99% of the 140 amp limit. It goes without saying that when the CPU tries to do something, it will hit the VRM limit and throttle as a result. Mind you, I didn't even overclock my CPU. I put my processor back into my X470-F and it worked flawlessly. Needless to say, I started the return process, bit the bullet and bought a x570 furniture (Asus Prime x570 pro) for my new build. I don't know if this is a problem for all b450 boards. However, the 105w processor seemed too big for this board and I didn't want to risk getting a b550 that couldn't handle my 3800x on default settings, let alone overclock it. This experience turned me away from the B-series boards forever. If you're using a 65W processor and don't intend to overclock it, chances are you'll be fine. But if it's in your budget, buy an X-series board. For my money, buying an ab-series board isn't worth the risk and limitations that come with it. Ps Gigabyte seems to have literally skimmed the corners on this board to keep manufacturing costs down. It's not a full-width ATX. So if your case doesn't have the ability to adjust the standoffs to accommodate the narrower width of this board, you'll need to use 6 of your 9 mounting screws. You should call it a new class. I think ATX-S is for slims. Thus, the buyer could recognize this design peculiarity at a glance.
