    I haven't had any problems at all! I bought it because I recently got an RTX4090 and it definitely gives enough power output. It's really a great PSU, would highly recommend if you need some power.

    I went from a 3080ti and ThermalTake 750W grad tough power RGB PSU which had served me well for about 8 years to a new 5080 GPU - Asus TUF version. I wanted to ensure stable power and also wanted the new PCIe connector for a simplified install. This bad boy did the trick!
