My understanding is YES, with the notion that you'd only have the output 
of the 1300W (1152W IIRC) available to the system, but that shouldn't be 
a problem for you at this time.

Caveat: I have had three 6509s fry simultaneously (ALL ports "inactive") 
due to DC power issues (it's the only logical conclusion I can draw from 
the facts available); the only thing thought to be good once the dust 
settled was the power supplies.  The cards showed ports 'inactive' when 
inserted into known-good chassis, the sups showed ports 'inactive' 
locally and on known-good linecards when inserted into known-good 
chassis, and the chassis showed ports 'inactive' when loaded with 
known-good cards.  So you may want to take my advice with a grain of 
salt.  ;)
