All the power I need, with the being able to use only the connections I need makes for the cleanest PC builds. Corsair is #1 in my opinion. Also this is super quite with a fan control knob on the back.

So far so good. It's having no issues powering my 7800X3D and 5080. The 12VHPWR port means I don't need the adapter. Cables are of a higher quality than I expected. They look good and come with cables combs, so it's a fairly clean look without having to get custom PSU cables.

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!
