    Good point, I should have said: it takes about 3000V to jump 1mm, so it would help with surges.

    HOWEVER, the circuit in a really good surge protector will not just absorb the surge but reflect it...

    Sloppy designs

    Spent yesterday upgrading capacitors on some power supplies (for fun), but found a terribly sloppy design.

    On an HP supply: a power transistor compressed between a capacitor and an inductor coil;...

    When you overclocked, did you use over-voltage? that can accelerate aging of components.

    What spare parts do you have to try? another power supply?

    20:20 says each capacitor is 200V 330 μF

    22:10 says they are in series to give 400V and 330 μF, but the combined capacitance should be half that.


    That said, these are still wonderful videos,...
