We study numerically an \(s\)-wave holographic superconductor from an anti-de Sitter-Einstein-Born-Infeld black hole with backreaction in the context of the AdS/CFT correspondence. By introducing a parameter \(G\) to tune the effects of the backreaction, we can study non-perturbatively how the condensation properties and conductivity of the superconductor change as the backreaction increases. We find that for small values of \(G\), increasing the nonlinearity of the Born-Infeld model makes the formation of the condensate harder -- consistent with previous results reported in the literature -- while for values of \(G\) close to one, the opposite effect occurs; increasing the nonlinearity slightly facilitates its formation. We also determine how the ratio \(\omega_g/T_c\) varies for different intensities of nonlinearity and backreaction, showing in particular that large deviations from the so-called universal value arise as backreaction becomes stronger.
