If you are unable to turn on your iMac and you do not hear the fans or the chime, the issue may be with the power supply. Bring in your iMac or iMac Pro to Good Zone so that our technicians can perform a comprehensive diagnosis on it.
During the course of the diagnosis, you will obtain reliable information regarding the problems that are occurring with your iMac. With this knowledge, we will be able to provide an accurate estimate of the cost of the repair. Because the problem could occasionally be caused by a short circuit on the logic board, we always advise running a diagnostic.
Bring it to us in either of the ways that you find convenient:
If your iMac's power supply is malfunctioning, the signs of this issue should be extremely clear to you. It is possible that your computer will power off unexpectedly and will not restart itself; alternatively, it may not turn on at all.
Before taking any action, we are going to first confirm if the power supply has to be changed or if it is an issue caused by just a few broken parts. It is possible that this repair will take longer than usual because of the nature of the problem. First, we need to determine what the issue is and then we can fix it by changing the malfunctioning component. Time depends on the fault; we tell you after diagnostics.
If the power supply has failed, we replace it once you approve the price, and we test the iMac before you pick it up.
You want your iMac power supply repair done by a service that tests the power supply before it replaces anything.
Our technicians are on-site at our Midwood store to provide diagnostic services and estimates to all our clients. We also handle other iMac repair work, from screens to logic boards.
You approve the price before any work starts; nothing is repaired without your yes.
Our iMac power supply repair cost is quoted after diagnostics. Diagnostics cost $75 and count toward the repair if you go ahead. Repairs come with a 30-day limited warranty.
From the iFix bench, June–October 2026 (our five New York stores, Good Zone included): 8 iMacs came in: 6 were repaired and handed back, 1 owner declined after the quote, and 1 was still in progress on 9 November. The median bill on a completed iMac repair was $272 (half of the bills fell between $171 and $403), and the median repair took about 2 days. Every repair is quoted after diagnostics.

Testing your iMac power supply will require the use of equipment called a multimeter and it is part of our diagnostics. Because it will involve taking your iMac out of its metal casing, it’s advisable to let professionals handle it to avoid damaging something or voiding the warranty.
You will need to first make sure that your iMac is properly plugged in, then you can try holding down the power button to restart it. If this doesn’t work, bring it to our Midwood store for diagnostics.
No. Some iMac models do, in fact, come equipped with a small battery; however, this battery is only big enough to power onboard components like the clock even when the device is not plugged in. It is not big enough to power the iMac in the case that there is a power failure, for example.
