Ok when you say that the yellow cable has 18v when on, do you mean the one that should be 12v? If yes, try the old PSU again. If the old one works fine, contact the cooler master about the problem.

Ok, get in touch with whoever you bought the new one from and see what they say, seeming as it works with other PSUs. You have most likely been sent a faulty one
