Question Can using a single PCIe power cable (pigtails) hard crash a PC to a black screen on a high TPD GPU?

Hello,

I have a 6800 XT Red Dragon that crashes in some instances under heavy load. I wonder if this can be due to the fact that I have a single cable coming from the PSU? PSU in question is an ASUS Rog Strix 750 W. I can't test daisy-chaining yet.

Yes it could.

Yes it could.

Is there any kind of math I can do to calculate the likelihood of this?
