    This PSU is not only amazing, but it is very efficient. It is able to handle my Graphics card overclock pulling over 400watts on that part alone.

    Recently added a EVGA 3080 Ti to my system and decided to upgrade my PSU while I was at it. I wanted to run 3 dedicated cables to power the GPU. This PSU has plenty of slots accommodate that. My system should be future proof for quite a while now.

    This is my second Corsair psu. I think they’re top notch, if you don’t want to spend money on aftermarket cables, the one it comes with are pretty good.
