    Great power supply with lots of cables depending on your setup. My only complaint is that they should have included individual sleeved cables with interlocking combs to complete what could have been a professional look.

    Had a CX750M for years with no issue, needed something more robust for a 3090. Cables seem a bit thicker ... maybe that's robustness at work. Fully modular, does the job, is super quiet at idle which is nice.
