Close to converged energies and expectation values for PsH are computed using a ground state wave function consisting of 1800 explicitly correlated gaussians. The best estimate of the PsH$^{\infty}$ energy was -0.789196740 hartree which is the lowest variational energy to date. The 2$\gamma$ annihilation rate for PsH$^{\infty}$ was $2.47178\times 10^{9}$ s$^{-1}$.
