con.clu.sive  (kn-klsv)
adj.
Serving to put an end to doubt, question, or uncertainty; decisive.

I don't think you will ever know "conclusively."  The best bet is to create
a TAC case and have them put a 1300W and 1800W power supply in a 65009
chassis loaded with the same cards that you have.  Good luck with getting
that done before your replacement arrives (it isn't there yet?)  I'd concur
with the rest of the engineers that say it should not be a problem, FWIW.

At least you don't have one of those funky power cords that were wired wrong
and when plugged in would energize the whole chassis.  That must have been a
shocking discovery!
