Any thoughts on trying a 4090 with a 1000 watt power supply?  Also have a i7 13700k, 32 gb ram and some M2 storage.  Newegg calculator says 800 to 900 watts.  Seems close.  Safer to go with 4080 super or is 1000 watts enough?

I have no problems with my 800 watt power supply, but my 5800X3D CPU ain't as power hungry as the intel CPUs.
