My mother was required to complete a Civil defense course as part of getting her bachelors degree in 1967 . Her degree was in medical transcription . So imagine a typist that knows how to spells complicated medical terms . All she remembers about the course was having to hide under things . I recently was required to attend training at work on how to deal with an Active shooter and couldn ' t help but see parallels between the two . All I can really remember from my course was likewise , to hide under things . <| sep |> I wouldnt worry too much , if at all . If you havent noticed any issues , the psu should still be very reliable . as you said it has more than enough juice to feed your rig . Hell if i where you , id probably wouldnt even consider getting a new PSU not that thats the right thing to do , im just really cheap lol
