    Very good nutrition

    This must be the 3rd one I've ordered in the last few years.
    Very stable voltage, in the silence of a cathedral

    well... but not for long :D

    Top-notch power supply. Top quality and varied connections. In short, everything went well for a year.
    THEN: It burns out !!!! :D...
    So now, on top of that, it's HYPER QUIET... that's that...
    So we buy another one.

    Great nothing to say :)

    I ordered the complete PC assembly without the Windows installation and frankly everything was fine, I have nothing to say about it, it was very well organised and the customer service I spoke to before the purchase was very good.
