    Good cable length

    I ordered a slim box at the same time, I received the box on Saturday and the power supply on Tuesday, however I ordered everything at the same time and it came by the same carrier. The cables are of good length, not too long or too short. The power supply has not been tested as I still need to buy some parts.

    Failure on unpacking

    No such luck: the power supply delivers absolutely no current!
    And it had to fall on me.

    Very good.

    Used in an Antec vsk2000-u3 case without any problem, its 300 watts are more than enough for a small entry-level HTCP or desktop configuration, possibly light gaming. For my part, it can handle a HTCP configuration with a Ryzen 2700 and RX 6400 low profile, where I must be at about 50% of this power supply's capacity.

    Perfect to fit on a Dell Optiplex SFF

    Good quality power supply, quiet.
    The dimensions are almost identical to Dell standards, but I couldn't screw it in, it just sits there. I also had to buy a 24 pin -> 8 pin adapter.
    I'm very pleased with the quality of the product and the service.
    Very satisfied.
