    Would you do what then? Replace SMC to test? By now do you think iMac PSU is 100% working? Is there any other test that I could make or the above makes it a working PSU?

    Is there a test to make sure iMac PSU is good or not? I think it's supposed to be good since it turn on without these things connected to the board.

    OK Why do you care for SATA if the machine does NOT turn on? for me it does not make any reasonable sense. The machine is in short connected to POWER how the HELL sata will make any difference. I already tried connected with SATA + POWER connector and its the same beahavior. However I REMOVE...

    Disconnect thunderbolt and ODD. Also remove HDD from the end cable; keep the cable connected to J4521. The board turns on and have LED 3, I didn't put the speaker but I guess it has chime also. I DO NOT HAVE NOTHING CONNECTED TO J4530/31 .....

    Of course the cable is OK Of course the cable is connected on the right position Of course the thunderbolt was connected the right way I am afraid the ODD connector I could plugged it wrongly since it came off the board..... only this one My latest test I only plugged the 2 power connector on...
