Sorry, should have been more clear.

Are you using a adaptor cable or a custom 12 pin cable for the 3080 and was wondering if that may be the problem.
good point.

An GTX 660 or even 670 wouldn’t require as much wattage as a 3080 so a faulty power cable wouldn’t show up as easily, especially in general use.

Never normally a good idea on higher end GPUs.

Can you change it for 2 x cables from the PSU to the GPU at all?

Do you have another system to test the 3080 in at all to see if its dead?

I have no other system capable, I will try the two separate cables at some point, looking at just buying a 7700xt and ebaying the 3080 as spares and repairs.

Yeah, good idea as can at least get some money back for it.

How old is the card? Is it out of warranty?
