We investigate the behaviors of scalar operator and holographic entanglement entropy in metal/superconductor phase transition with Power-MaxWell electrodynamics in higher dimensional background away from the probe limit. We observe that the larger Power-MaxWell parameter b makes the phase transition more difficult and the critical temperature decreases more slowly as the factor b increases. In the belt geometry, we find that the holographic entanglement entropy is a powerful tool to probe the critical temperature and the order of the phase transition. At the phase transition point, the entanglement entropy increases with the increase of the factor b and the belt width of the geometry ℓ. Interestingly, the width ℓ has no effect on critical temperature of the phase transition.
