Dead PCI-E cables on TX750


Recommended Posts

The PSU has worked fine for the past 3 months. This evening, I add a second GPU and it doesn't power up.


I switched the cables from GPU1 to GPU2 and vice-versa. Now, GPU2 has power and GPU1 doesn't.


My only other option is to try the 4-pin-to-PCI-E adapters that came with the GPU.


I probably need to upgrade to a larger PSU anyway to support the extra card. Even so, I still would like this PSU to be fully functioning in case I put it in a backup system.


Any thoughts?


*EDIT - After moving the cables around some more, GPU2 came to life. Not sure the cause, but perhaps the cables weren't fully seated. :confused:
