    As described

    This is my first modular power supply.
    Easy to install, the cables are long, no worries about connections.
    No or extremely low noise.
    I recommend this product.

    Noisy product

    The product is very noisy. It's a shame. Is it the computer case that's making the noise?

    Very satisfied

    Classic semi-modular power supply, nothing to complain about after one month of use.
    Its strong point: it is very quiet! Combined with other silent components, this results in a tower that sounds as if it is standing still.

    As I have a glazed tower, I could only complain that the labels are stuck on the wrong side and therefore visible from the outside.
