    Ease of use

    I have nothing to say about this power supply, which replaces a Noname that burnt out my last PC (thank you Materiel.net for putting Noname in your pre-built PCs...).

    Very easy to install and connect. The only downside is that the cables are a bit short for owners of large towers, but that's nothing insurmountable!
