What does "Input Frequency Range" mean in a psu?

Hey guys! I am currently looking at a psu to run my gaming rig and I found this one! I was looking through the specs and this is one of them "Input Frequency Range" it's at 50/60 hz I am planning on getting a higher hz monitor so will it still be able to run at 144hz (my monitor) or do I need a new psu?

  1. Yes. That's what the incoming AC should be running at. Most of the world runs on 50 or 60hz. The USA runs on 110V at 60 hz. The monitor is something else.
  2. Old CRTs used to reference off of the line frequency, everything is digital now so power goes into the power supply, gets converted to DC(no frequency), then gets converted to what ever signal is needed at whatever the desired frequency is. Most things these days have universal voltage input so they work in North America, Europe, and Asia(japan is kinda a mess) so you don't need to worry about it.
  3. Best answer
    The monitor frequency you refer to is the refresh rate of the monitor screen, not related to electrical power input.
    Most common frequency, slowly being replaced by monitors like yours, is 60Hz.
    It is how fast/frequent each line of the display is refreshed or replaced.
