      - Sometimes these outputs can be related to bugs. Can you check the (green) status-led on the power supply ?

another bug check it,

[brijesh yadav]

LED is orange for disabled power supply. Other powers supply LED is green.

Re-seat the power supply.

[brijesh yadav]

Already done,but same issue.

[Leo Laohoo]

RMA the power supply. 
Orange LED indicates a faulty PS.

[marce1000]

  - If it remains orange, check (input) feed , if that is OK ,then I guess the power supply is 'just bad' and you need to get another one.

visually inspect the power feed of that power supply (inner).
