    Silent power supply

    The power supply is quiet and seems to be of good quality for this price level.
    The connections to the motherboard and drives are simple.

    satisfied

    I chose this power supply for its qualities and recommendations; not being a gamer or a media player, the 400 W are enough for me.
    The only small problem: according to the manuals, it was not obvious to place it in the case for the direction of air intake/rejection.
    A LDLC technician reassured me that it didn't matter and that everything would work properly, which is what happens.
    The wiring is solid and that is more than enough.

    Very good product

    I needed a new diet and turned to this product.

    I am very satisfied with the product: the cables are protected, it is silent as its name suggests, and it does not consume a lot of electricity.

    My main uses are office work and "light" video games. I don't use a specific graphics card.

    quiet power supply

    quiet power supply that does the job, sheathed cables to prevent shearing.
    Nothing to complain about for this price.
    I should have just taken a more powerful power supply. I just wish I'd gotten a more powerful power supply, because with the addition of a graphics card, it's going to be light.

    good food for cheap

    A good power supply for a not too greedy configuration.
    Very quiet as expected from be quiet!
    Cables are long enough for a medium tower case, many sata connections...
    Good value for money

    Perfect

    A very good four hundred watt power supply certified "eighty plus bronze". It is very quiet and does not make any noise or other audible disturbances.
    Be quiet! is definitely a very good brand.
