I have been racking my brain trying to figure out which T2 from EVGA I should use. Setup:

z490 dark k|ngp|n edition
Siliconlottery.com binned, delidded 10900K
3090 ftw3 ultra
4400MHz GALAX Hall of Fame OC lab 2x8GB
soundblaster AE-9
samsung evo plus 1TB
arctic freezer II 360

I want to clock this CPU to 5.4GHz at 1.45V. I’d like this memory to push 5.1GHz. This alone I’ve read will draw up to 400W. The 3090 ftw3 ultra draws up to 460W at peak 106% overvoltage sider on Precision X1.

I am concerned. The 1600W is overkill, but the 1000W PSU maybe pushing SLIGHTLY over 900W. Should I factor in “best efficiency is at 50% power draw” here? I am SO stuck with this decision. I am going to be using this machine for RDR2 and Cyberpunk but I want to also use it for benchmarking a few times... so I have to pick here one way or another? If benchmarking I will have to use the 1600W, and for gaming much less probably the 1000W as gaming doesn’t max out CPU and GPU at the same time.

1300watt model? Extra cushion?

If the price is right it wouldn't hurt. There's something to be said about keeping your psu closer to the 50-75% load area to improve efficiency and potentially reduce fan noise.

Does anyone have a 10900K with a 3090?

I would greatly appreciate the help from someone who is pushing both to extreme overclock levels to chime in! I have both PSUs sitting at my feet, unopened. One must be returned!

Again, I know one will run hotter than the next, more fan noise, etc... I would like some more input & opinions

^^^^ This !

is there even a point in sound cards anymore?

Sound cards?  Unless you have an ancient motherboard or a defective motherboard, no.

I'd suggest a 1300w PSU if you were wanting to run two RTX 3090's in NVLINK. 1000w is more than enough for one. Even a base-line system, Guru3d recommends 750w PSU for the founders RTX 3090 which might not take as much power as yours.

5.4GHz is easy for any i9 10900K, just need the right motherboard for it. When playing around with my i9 10900K I found a manual overclock to 5.3GHz all core was the most stable... but honestly, the built in overclocking software runs it well past that and only pushes the processor when I'm playing games.
 
A Platinum certified or higher 1000w PSU would easily keep up with your needs. Just depends on how many accessories you want connected to... For instance, I have a similar set-up but with a RTX 2080Ti instead... I also have 2 D5 water pumps and 9 120mm fans hooked up to it.
 
If you watch things like GamersNexus, don't get caught up in the LN2 stuff. They are using a crazy amount of voltage just for those benchmarks. It's also the most advanced in terms of overclocking and a 1600w PSU is what they use for that kind of stuff to make sure there is no shortage of power.

FWIW, at one time I ran two 1080 Tis OCed to 2025MHz (and +500 on the VRAM), 8 spinning drives with a PCIE RAID controller, a PCIE SSD, a dual 10 GbE card, an X99 Classified, an Intel 6950X at 4.4GHz, 64GB of 2800MHz RAM overclocked to 3200MHz (8 sticks), three AiO water coolers, and about 10 fans of various sizes - all on a platinum 1000W Seasonic without issue.
 
I'm betting I was drawing more power than you will. 
 
With that said, nothing wrong with going with a 1600W Titanium EVGA PSU - I'm actually running one now (popped it in when I upgraded to an X299 FTW K and a 10940X).

Since I got a binned 10900k and z490 dark kingpin... i want to really push this CPU hard, also went out of my way for a 5.1GHz overclockable RAM kit...

I’m fearing the CPU may pull over 400W at the same time the GPU pulls 460W.... this will be a problem, if not at least be very inefficient as the efficiency curve does’t behave well at 90-100%

There is no EVGA titanium 1300W

Aside from the obvious efficiency improvement, when comparing across the same platform, platinum supplies typically perform better than titanium, and gold performs better than platinum.  It's because they don't have have to make as much of a compromise for efficiency.  That 1300w Seasonic Prime Gold I got is quite possibly the most performant psu on the market, except for efficiency.  IMHO the best performing psu that EVGA makes is the 1600w G2 (super flower leadex gold GTX), though the 2000w G+ foreign market model that Kingpin is using might be better.

Looks like the 1200w P2 is pretty good.

I just think, let’s say 3090 hits 440, cpu hits 330, sound card 75... well that’s like

845.

add in fans, m.2 ssd... and even make that 3090 from 440 to 460...

that’s still max 950 right? THESE ARE ALL MAXED! meaning it cannot possibly draw more than 950 ever

That's correct and it's unlikely all of them will ever be maxed out at the same time..
