    Powers a 5080 and 7800X3d and 6 x 140mm fans

    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!
