The coil whine from this was very loud, unacceptable for the price, but after I returned it I was told there were no issues and it was "within tolerance".I still got a refund and went for the Vertex Prime instead. Runs completely silent. I highly recommend the Prime for no surprises.

Seasonic does it again! Extremely well-performing power supply, with a quality that is felt as soon as you take it out of the package. Feels very well built. It's expensive yes, but you get what you pay for. Seasonic is in a class by itself.The only thing I think is a bit like "that" are actually the cables. Good lengths and such, but everyone thinks they are a little too stiff. It can be a bit of a pain to get it looking good. But otherwise, I only have good experiences with this grudge (and Seasonic in general)
