We study the matter power spectra in the viable f(R) gravity models with the dynamical background evolution and linear perturbation theory by using the CosmoMC package. We show that these viable f(R) models generally shorten the age of the universe and suppress the matter density fluctuation. We examine the allowed ranges of the model parameters and the constraints of the cosmological variables from the current observational data, and find that the dynamical evolution of DE(z) plays an important role to constrain the neutrino masses.
