    I'm very happy with it, and it should stay with me for a long time.

    Power supply purchased to replace the old one (an LDLC 750W 80PLUS Platinum), which had failed to start up after nine years of service. The layout of the sockets is simple and makes it easy to connect the components. There's nothing wrong with the wiring. The Serflex plugs supplied free of charge with the power supply are a nice touch that I appreciate so that I can arrange the cables neatly. The power supply is silent as promised. The 10-year warranty is very reassuring. I'd definitely recommend it.

    efficient and silent

    slightly disappointed by my 1st modular power supply.
    I was counting on a perfect management cable, but it didn't work out, the cables are a bit too short:
    You can't run them anywhere you want in a Corsair Obsidian 450D, and you have to plug in 2 to connect 3 SATAs (1 optical drive, 1 2.5" SSD and a 3.5" drive).
    a shame!
    and no extra cables apart from the 12VHPWR, which I don't (yet) have any use for.

    EVERYTHING IS OooK

    I received this power supply this morning and everything is as described.
    going from 600W to 850W it gives a breath of fresh air especially with a 4070 ti super.
    Very fast delivery.

    High-performance power supply.

    Hello,
    This power supply performs well and is very quiet, but I'm having connection problems. On the power supply side, the plugs fit very well. On the other hand, I had trouble connecting the power cable to the motherboard, it was 3/4 in and I had to force it to complete the connection, and the same for the pci -e. I was scared at first but it worked all the same. Next time, I'll get a Corsair or Seasonic.

    pleasant surprise

    Modular power supplies are always a delight.

    This one is well designed. It has a PCIe5.0 connection, which is really top-notch for a fairly affordable power supply: it's not one of the manufacturer's top-of-the-range products, but it stands out all the same.

    Very easy to install, and very quiet, as always with be quiet.

    A good investment for larger configurations (gaming or multimedia).
    Note that the manufacturer's website has a tool for calculating the power supply required for your configuration, and (of course) suggests its products according to your power supply requirements (number of connections, etc). Very useful for checking whether or not you need to make a purchase.
