    That explains why my ANTEC power supplies have died. Although some were made by Seasonic, they were NOT designed by Seasonic.

    As you were told with the last one, chokes do not mean passive PFC. They will be present in the filters (all of them, including input) of any PSU.

    "For those companies that don't manufacture their own products, such as HEC and Seasonic"

    Huh? Since when Seasonic is not the maker of their products?
    Nice article and much needed. Thanks
