No. If you track how the statements have evolved over the years “the benefit of a doubt” is not merited, full stop. Look, I don’t live...

Yup, got that from one of your screenshots (and the "stop" login as well).

There are still new AT power supplies as well. Like this Athena on Newegg: https://www.newegg.com/p/2VH-02DY-00001 But they might not...
