[Retroworldnews]

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?

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.

Old age and your model iMac is noted as having PS problems. Have a look at this from ifixit. The ifiixit link also shows on the next page PS units for sale from $90.00 and a 30 minute job.
