Welcome to TPU. . . .
If the GPU was the last piece of hardware to be installed into your system and then the PSU died then yes.
At cold boot power gets seriously sucked out from a PSU for the first few moment and may have burnt out a worn/faulty component in your PSU causing the smoke and death.
My mates PSU did this a couple of weeks ago but it was a generic job.
He used to have his PC on nearly 24/7.
He's currently using another generic which I think is weaker and is starting to make odd noises but thats his own problem.
