    imac 21.5 late 2015 power supply replacement
    Have a imac 21.5 (late 2015 emc 2833 2.8 ghz) that shuts down and refuses to power up.

    Looking into doing a power source replacement. Any advice?

    My personal preference for D-I-Y repair guides is ifixit.com. Here's the one for the Late 2015 model year, iMac Intel 21.5" EMC 2889 Power Supply Replacement - iFixit Repair Guide.

    Please backup. Everything has a life cycle, unexpected and warning free. Nothing will last as long as you want it to.

    Welcome to our forums.

    First, you need to make certain that it is the power supply. Are you able to startup your iMac at all or is it dead? If it starts and then shuts down, it may not be the PS.

    But if you do need a PS for your iMac here are some suggestions:

    1. eBay

    2. Mac Parts on line: MacPartsOnline.com - The Apple Parts & Mac Parts Store

    3. Powerbook Medic: Mac Repair - Mac Parts and Service for Apple Macbook, iPhone, iPad

    4. iFixit: The Free Repair Manual

    Love the A26...
    The iMac will shutdown from sleep. The iMac will shut down when in use.
    I unplug it, reset smc and sometimes it will restart.

    I am excited to try this. I love repairing stuff.

    Thanks for the advice! This is my very 1st iMac repair. It was so simple. It took less than 1hr to do. The iMac is operational again.
