Can you explain what you mean by "wrong bond connectivity"? What was the
exact process by which you reached that conclusion?
The atom names in atp_namd.pdb (which I assume is your input to psfgen) do
not match those in the residue definition. This will result in a lot of
coordinate guessing, which is not always good in psfgen depending on the IC
table definition in the RTF.
