Question CORSAIR RMx Shift Series RM1200x

[Ahumado]

I have a Corsair RMx Shift Series RM1200x PSU. I installed to an ASRock Z97 Extreme Mobo. It started right up and I used it for a few hours. The next time I started that system it would "turn on" but I could not get it to output to the monitor. I spent a few hours doing all the usual troubleshooting (reconnecting plugs, moving memory, swapping cables, new outlets) but it would not start. I contacted Corsair and they had me do the "paperclip" test and it checked out. I have a PSU tester and following Corsair's instructions the PSU was determined by Corsair, based on the data from the PSU tester readout AND that the system starts right up when I put the old PSU back in, to be faulty. Today the replacement PSU arrived and I have the very same no boot issue. What am I missing? What is Corsair missing? Any help will save me further skinning my fingers. Thanks

Out of curiosity what is the old PSU? It's possible that even the replacement is defective. Is there any chance you could try the new PSU on a different system? Perhaps a friend's PC? Did you use new cables when the new PSU arrived or did you use the same cables from the original Corsair?

Corsair TX 650. Yes it is possible the replacement is defective. On a different system is my next move. I used the cables that came with the new PSU. Thank You
