    Very positive

    I am very happy with my purchase; the advantage is that you can get a good power supply. My previous one, bought second-hand and unbranded, died in less than a year. Here it's a different story because you can enjoy a very good brand new one without breaking the bank. It's a really good option; I recommend it especially for smaller budgets.

    silent and effective

    The fan remains discreet even under load. Finally, the integrated protection against overvoltages and short circuits reinforces safety.

    It is a good PSU that remains an excellent choice for those looking for a reliable, high-performance and affordable power supply.

    Product reviews

    The product is satisfactory but I think that choosing the modular model would have been more judicious. The assembly by your after-sales service surprised me because the cables were not installed in the cable management but in the case, cluttering it.

    PC power supply purchase

    Power supply from a well-known brand working perfectly despite the differences in connection plugs to the various hard drives of a tower that has now been in operation for several years.
    This remains nonetheless and after installation of connectors "that fit well", an excellent product.
