Hi guys,

We are putting together a new machine and using the GPUs from a previous build.

We had a pair of 780 ti's in SLI and they were running fine together on the old machine,

Now we have issues in the new machine and after narrowing down the problem to one of the gpus we are stumped!

One of the GPUs alone works fine. In SLI the system powers off after 30 seconds or so. We switched the GPUs around and same issue and then finally tried the second card alone and git the same issue again. Therefore we presume something is going on with that GPU... but what?

It was working fine a couple of hours ago and has been handled correctly (we have built many machines now!). What could be the cause here? For the record we are using the same PSU as before as well (Corsair AX1200i)

appreciate any help
