Question What PSU that's future proof for an rtx 4090?

[Wonderclam]

I'm looking for a back up power supply for my gaming PC. I want one ready to go if mine ever fails, even though mine is only 2 years old.

I want one that is quiet, very reliable, will fit in my atx case, and something that will work with an RTX 4090, if I decide to get it in the future

Tom's Hardware ranks
Corsair CX450
as the number one PSU, but I think 450 watts will not be enough for an RTX 4090?

FWIW...I've already purchased my i9-1290KS and NH-D15 Black and I'm about to buy the 3090 Ti Ultra from EVGA for this build. https://pcpartpicker.com/user/frodoz737/saved/zYJZcf To power this I'm picking between these linked below for the quality. The 40 Series cards are rumored to eat a lot more juice and you don't want to cheap out on the PSU.

Just wait for some reviews and see what they really use.
