    ooh, I read this article about the ST40EF. Very nice.

    I think this will be my next PSU for my HTPC case. Sounds very good.
    I wanted to kick out my old Noname PSU in any way, as it is getting too loud.

    Now I read, that even efficiency is very interesting in new PSU's.
    over 80%, thats great, I do not want to know, how less efficiency my noname has......

    Thanks for the Review and the informations guys.
