    Today I just went to fix my old iMac mid 2011.

    According to the repair man , he checked and is my power supply spoilt and . he replace it ,

    is working now .
    He also told me power button also faulty , aka means intermittance. That problem I know.

    Due to urgent need the iMac , so I never get repair the power button , only the power supply.

    so my question is ,

    if you left your iMac 24/7 365 never turn off , only turn off the display when go to sleep
    just left it on listen online radio ,

    will make the power supply get faulty faster?

    For most electric appliances turning it on and off is more stressful than constant running.
    I never shut mine down.

    I do not believe you could hurt the PS in any normal usage of the computer.
    If it lasted 8 years, then it has done good job already. Switching power supplies mostly suffer from electrolytic capacitors drying out.
