grammar - Are there rules governing pre- and/or post-modification of noun groups by participial adjectives?

Which of the expressions "supplies needed" and "needed supplies" is / are correct?

1. Have we now received all the needed supplies?



2. Have we now received all the supplies needed?

Is there a pattern one can use to predict whether a participial adjective is used prenominally, postnominally, or both? And if both, may there be differences in meaning?
