    Magnificent

    It's an excellent power supply for my configuration, reliable, silent under moderate load, and upgrade-proof with ATX 3.1 support.

    Very satisfied

    Recently purchased
    Very good quality and powerful ;) It's also quiet
    The cybernetics 80+Platinium certification (if I'm not mistaken) is a very good thing
    Much better quality than just 80+platinium, for example

    Corsair's multi-year warranty is real proof of quality and solidity ;)

    Flexible and robust

    Very well built (as has long been the case with Corsair power supplies), you can manually control the fan using a pot at the back, the fan remains relatively quiet even at full speed, there's enough room to see what's coming and the cables aren't laid out in layers with each wire glued to the other, which makes them more flexible and facilitates clean cabling.
