    Can do better

    1st reservation: the parcel arrived in bad condition, the box, twice as big, did not contain enough padding and the weight of the moving power supply simply burst it. Fortunately the Post Office wrapped it with tape so that it wouldn't lose its contents.
    2nd reservation: one of the threads is not straight, so a fixing screw is crooked, which is not acceptable for a product of this price.
    As for the rest, I'll see with use, the installation dates from yesterday.

    Nothing to complain about

    It's all in the title, this power supply totally fulfils its objectives, silent as possible (replacing another rather noisy power supply, now when I turn on the computer it's happiness in the kingdom of silence) even under full load. The packaging is quite classy (at the same time for the price, it is rather normal) and the cables are well thought out.
    So all in all it's exactly what I expected and more.

    A power supply with exemplary finishes.

    Very good power supply, the finish is excellent. The bundle is very complete and of very good quality (cables and sheaths). The power supply is totally modular which is a big plus for the assembly for the cable management. Very quiet, nothing to complain about on this model.

    For my use nothing to complain about, or almost nothing!

    The food is not cheap, that's for sure, but at least I am not disappointed.

    It's quiet, I don't hear it or the other components cover its noise.

    Comes with lots of cables, good quality.

    I bought it partly because of the fact that it manages the fans itself, but I don't have the impression that their speed increases so much when used a little bit more (not a problem in my case because of the good air flow, but I think that the components could be cooled even better).

    So if you want something that is really flexible and blows as soon as you play or whatever, maybe it's wiser to go for a rheobus or to have a lot of pwm connectors on your motherboard (I don't because mini-itx).

    I'm not sure if it's a good idea to buy a new power supply, but I'd probably go back to this one!

    A very quiet power supply.

    Easily feeds the following configuration :
    . MSI Z170A GAMING PRO CARBON
    . ZOTAC GeForce GTX 1080 Founders Edition
    . Intel Core i7-6700K (4.0 GHz)
    . be quiet! Dark Rock 3
    . Samsung SSD 840 510 GB
    . Samsung SSD 850 EVO 2 TB
    . 3 fans 120mm THERMALTAKE RGB
    . 2 x 140mm THERMALTAKE RGB fans
    . InWin 805c black/red case
    . hub with USB lamp and various external devices

    No luck for me, I received a case that didn't work but for a be quiet! it's very rare.
    Returned following the indications of the LDLC team and at their expense via the post; a few days later the new box is there and works perfectly in total silence!

    pretty and efficient

    This power supply is simply inaudible. Of course I don't use all the power, but it leaves some room for decibel.

    The cable set is very complete, even the packaging is beautiful (yes, it's important when you choose this type of product)

    be quiet! Dark Power Pro 11 550W

    I would not judge yet of the general quality, it has just been assembled and the first impression is that it is silent, for the remainder, that will be to follow, the point which I find inadmissible on a power supply of this type, it is the impossibility of screwing one of the four fixing screws, I have abandoned the hand screws, even out of the case, impossible, it took the screwdriver and force to redo the thread, this more traces of white sticky paper on the top, puts me in doubt, new, case reconditioned, power supply reconditioned????

    Excellent alternative to the best Seasonics

    To be honest, I even prefer them to Seasonic's high-end models. This is not my first time, as I have already equipped several PCs with the Be Quiet "Dark Power Pro" series. I chose it for its silence, the quality of the power, the modular aspect, its effective power and its 5 years warranty. As a gamer who consumes more energy than a simple office use, with a ton of USB powered devices and letting the computer run around 14 hours a day and sometimes several days in a row, the power supply does its job perfectly. Even my first Dark Power Pro 10 bought 4 years ago still does its job perfectly.
