great reliable motherboard
27 April 2025 
Bought it with a Ryzen 7 5800X processor, everything started up the first time without any issues. Also got Kingston Fury DDR4-3200, two 16GB sticks, installed them in slots 2-4 (leaving the first one after the CPU free), and it booted at maximum frequency as it should. A bunch of ports on the back panel, there's a BIOS reset button, everything is nice and well thought out. The lighting isn't too bright and slowly transitions through all colors. I'm not a big fan of lighting, but this one is subtle enough that I don't even notice it. I always opt for a full-size ATX to avoid any surprises during assembly, like RAM interfering with the CPU cooler or something else. Also, maybe a minor detail, but I noted for myself—this is my first motherboard where the ports on the back panel are enclosed in one solid block, or whatever it's called; when installing in the case, it's much more convenient than having a separate grille for connectors. I really liked that because it makes the assembly much easier. Overall, I can't even think of anything bad to say; everything was perfect during assembly. I'm glad I chose it and hope it lasts a long time.
there's everything you need, thoughtful design
nope

A good board for a mid-budget build.
14 August 2024 
I took it under Ryzen 5600. RAM G-Skill Trident (2/16)=32 GB. Everything started and started to work like a Swiss watch.
Vrm of the power supply, backlight, appearance, 4 slots for RAM.
First of all, the bios, although the version was the penultimate, but I had to tinker a little. After that, I updated the bios, everything fell into place.
