  The discovery of a standard model (SM)-like Higgs boson with a relatively
heavy mass $m_h$ and hints of di-photon excess has deep implication to
supersymmetric standard models (SSMs). We consider the SSM extended with
hypercharge $\pm1$ triplets, and investigate two scenarios of it: (A) Triplets
significantly couple to the Higgs doublets, which can substantially raise $m_h$
and simultaneously enhance the Higgs to di-photon rate via light chargino
loops; (B) Oppositely, these couplings are quite weak and thus $m_h$ can not be
raised. But the doubly-charged Higgs bosons, owing to the gauge group
structure, naturally interprets why there is an excess rather than a deficient
of Higgs to di-photon rate. Additionally, the pseudo Dirac triplet fermion is
an inelastic non-thermal dark matter candidate. Light doubly-charged particles,
especially the doubly-charged Higgs boson around 100 GeV in scenario B, are
predicted. We give a preliminary discussion on their search at the LHC.
