Yes, but PSSM is mainly usefull for shadowing large scenes with a directional (sun) light. Shadowmap aliasing increases as the light moves further from the shadowed objects, so PSSM is not needed for omnidrirectional lights (since they are mostly used in indoor scenes).

Using it only for the sun leaves you with 4 depthmap renders and one normal render. That's acceptable on modern hardware and gives you shadowing for the entire scene.
