When you did the paper clip test, did you check all the voltages on the connector (Drenlin asked you about a multimeter)? While they may be no-load voltages, if incorrect then the PS is an issue. The Power OK connection should be high too.
Edit: I could not tell from the catalog spec if the input voltage is auto- or manual-set. Is the PS set for the correct mains supply voltage?
