    Default Hello friends, any advice on PSU selection?

    My system is a 10600k that I am looking to overclock paired with a 1080. I have a 500 or 550w Seasonic Focus Gold Plus from a few years back. I think I need more watts for this chip overclocked and GPU?

    650w? I am located in Canada and would like to spend up to $200 CAD to protect the hardware. If you have any advice it would be greatly appreciated! Thanks.

    The system consumes max 400w with OC. 550w Focus Plus Gold is fine. Keep it.

    to protect the hardware.

    Overclocking can damage equipment, or at least accelerate aging.

    As I understand it

    P ~ V2 f and f ~ V

    Where P is power, V is voltage and f is frequency; putting this together one gets

    P ~ f3

    so the power goes up very quickly with overclocked frequency (if one is raising the voltage to get that frequency)

    While that may be true over an entire range, in my personal work I have found that voltage requirements stay low until one reaches an inflection point, when the need for power skyrockets. Personally, I advise finding that inflection point, then backing off 200-300MHZ.

    Conjecture:

    Perhaps you are first using up the safety margin (no voltage increase needed)

    P ~ f

    and then finding the need for more voltage?

    P ~ f​3

    Just playing with ideas here. For me reliability and longevity far outweigh some extra speed.

    But what's the fun in that?
