    Great PSU, frustrating and potentially ugly cables

    Well-built & quite heavy, handles a 12700k and 3080 ti beautifully. I have to knock of one star for the cables Corsair includes (especially the mobo power) as they are unbelievably stiff & take work to get them looking presentable.

    Power seems to be stable and handles my components without issue. I will say that if you are worried about aesthetics inside the case, you may want to think about getting some custom cables. They are bulky and cumbersome in my O11 Dynamic.

    Very good power supply. Only complaint is the pretty mediocre cables that you would expect more out of a 70$-80$ lower end power supply.

    The wires are stiff and stick out, with out much flex, so this was a struggle to get in my case. But it fixed my (pc shutting down) problem. So its worth it.

    Corsair PSUs are undoubtedly the best! But I will need something with higher wattage (1200) for future GPUs!

    Likely the best Power Supply for the 1000W Gold class. It was the latest design from Corsair, quality build and good value.
