Simple, quality A520M motherboard. One fan header, no pump header though. Looks simple, works with all lower end 4000 and 5000 series Ryzen chips. Performance is great!

### ⭐⭐⭐⭐⭐ A good company means a good product
*by P***R on 7 February 2026*

A good company and a good product. But I had a little trouble starting my computer, with a 1TB M2 SSD and an RTX graphics card, because this motherboard requires a BIOS update from the moment I bought it. Without this update, my PC wouldn't boot. I installed a gaming computer with RTX graphics and two monitors on it. I've had it for almost a year now and I'm happy with it. Overall, I recommend it.
