PSU on my 2009 iMac Intel 24" EMC 2267 is dead and I have a working PSU from 2008 iMac Intel 24" EMC 2211. Is it possible to use the psu from the older imac as a replacement? Thanks!

No. The 2008 uses a 661-4665 or a 661-4478, it is compatible with the 2007 but not the 2009. The 2009 uses a 661-4995 and is a different form. The 2009 will use these part numbers: 614-0416, 614-0432, 661-4995
