power supply compatible parts
my power supply is buzzing, imac mid2011 27" i5 2.7ghz.
want to replace, part number should be 661-5972 but everywhere from all sellers is a picture of model 614-0446 even on ifixit(can clearly see P/N: 614... is this compatible part for all 27" iMacs? or those pictures are just for ilustration purposes?
Is this a good question?
