Would you upgrade to a 5090?

Final Edit: Thank you, everyone, for all of your input. I feel a lot better about using this upgrade, I guess I'm just more paranoid about that connector than I should be. knock on wood

Would you do it? Would you upgrade if you had the chance?

I have a 4090 FE, and can upgrade to a 5090 FE, but I'm super paranoid about the power situation. I know this is very much a first-world problem, but please entertain the idea and with the info we know about how that connector works.

Edit: To clarify, for me, it would only be about a $400 difference once I sell my 4090 FE to a friend, if I decide to keep the 5090 FE.
