Take the case where you have two switches on an RPS with one supply. Then if the power supplies in both switches died simultaneously you'd only be able to power one of the switches. A pretty unlikely scenario, but it depends on how paranoid you are.
With six switches on an RPS with one supply there's a bigger risk as you're betting that after one failure you won't have any more failures before you can swap the failed supply. In that case you might be safer with two supplies in the RPS.
Of course, if you have 3 failures then one RPS won't help - you'd need more RPS. Like all areas of networking you need to balance the cost vs. the benefit.
