We study phenomenological aspects of the minimal SUSY standard model with extra U(1) gauge symmetry. We find that the lightest Higgs boson mass can be increased up to 125 GeV without introducing a large SUSY scale or large A-terms, in the frameworks of the CMSSM and gauge-mediated SUSY-breaking models. This scenario can simultaneously explain the discrepancy of the muon anomalous magnetic moment (muon g-2) at the 1σ level in both of the frameworks, U(1)-extended CMSSM/GMSB models. In the CMSSM case, the dark matter abundance can also be explained.
