Thank you all for your information.
All higher-end gpus have 2 or 3 connections, so if for example i power 1x3070 which has 2 connections there should be no melted connectors? because 2 connectors would be able to support up to 300W?
If so, then this melted connector problem should only apply to really powerful cards, like 3080ti, 3090

Each situation is different, but let's suppose you're mining with a 3070, it's something like 150w from the wall with adjustments, so 2 connectors is way more than necessary.
If you are gaming or using 3080, 3090 etc and have all cables, it's better to use 2 separate cables to power your card, 2 PSU ports.
I found an interesting image, I think it's from Seasonic old manuals:

But now they do the manuals with a slightly difference:
