    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.

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