how many DRUs do you have?
if you have DRUs 1 to 3, you will have 2 at least… if 4 to 6, 2 PSUs will be enough, but won’t be enough once 1 PSU fail…usually, 4-6 DRUs were delivered with 3 PSUs. 1 PSU is 1500W.. a full config cabinet loaded with traffic will consume 2200W.. so 2 is enough when 1 will fail, but needs to replace to avoid total failure.
