12VHPWR or 4 x PCIe ?

I’m using the adapter.

Could using the 8 pin PCIe adaptor that comes with the cards be the safer option for now?
It probably won't fail on the PCIe side and if it fails on the GPU side they can't reject your warranty as you used the adaptor they included.

What would stop them saying it was your PSU in any case? They can just say it without even looking at it in person and that's it. After that happens, you can have a long legal battle in front of you, to get it fixed.

They'll struggle to reject it, I think, if you use your PSU's native cable as well. But as per the end of the video... if you have to go the RMA route, just don't say anything about the PSU.

There's absolutely no science to this, to be honest, not least because there aren't really enough data points. But it feels like there's a trade off if you use the 8 pin adapter, whereby you gain a little safety through spreading things across multiple ports at the PSU end, but potentially lose a little if the bulk requires a tighter bend in the cabling in your case.

tl;dr version: Just don't do anything obviously stupid and hope for the best.

Spreading the load on PSU side of things do not seem to be making a difference. The problem is almost always on the GPU side of things where differences in resistances on cables cause overheating of specific pins and then plastic melts. It's only few W on 1 pin required, as it's a tiny connector and few W is a large amount of heat already. Increasing number of cables coming in makes no difference as number of connectors on GPU side do not change either way.

On the plus side, it hardly ever actually kill GPU - replacing (soldering) connector seems to be the cure when this happens.
