Just got this today. Haven't hooked it up to the motherboard yet. So it fails the Dr Power II test on the power good (PG) signal to the motherboard. It will also pass the same test every now and again. It always passes the built in self test, but I don't think the self test performs the PG test.
See pictures below of the dr power failure, dr power pass and self test pass.
Should I RMA it?
