What are the rest of your system specs?

You are right. I did a quick google search and it looks like the 440watt range is normal for sure. I also see the BIOS update for 500watts also, which I am definitely not running. I jumped the gun making the post before googling. Its been a long day. 
 
Anyhow, I will try to undervolt and see how it performs and if it atleast stays on. 
I did notice, in the brief amount I was able to run the game, FPS was lower than usual and in the particular title I run, it uses and R and G meter to monitor Render and Frametime rates and they were higher than usual compared to how my 3080 was with no change and then BOOM it powered down. 
 
I am throwing the towel in for tonight and will test some more tomorrow when I have some time. Thanks for the suggestions.

Sounds like something an undervolt will be at least a temporary solution for until you can get the PSU situation sorted.  That should lower the draw enough to keep it from shutting down, I think the most I saw while gaming at that setting was 430W or so of draw, and that was in Cyberpunk 2077 with RT stuff maxed at 5120 x 1440, so the GPU was under pretty much the most stress it can be put under outside of Furmark or a similar "burn"/power virus type test.

I ran a 3Dmark Timespy benchmark and saw a max 426w draw. When I loaded up my game it was showing a 440w max draw. 
 
What software aside from HWinfo can I run that will log the values and save incase it shutdown? I like how you can view it in a graph style in MSI afterburner live or go back to it. But the problem is, I have to run my title in full screen mode so I cannot overlay the hardwaremonitor over it in a window to watch it live. I need to go back and view it, unless it doesnt crash then I am ok. I run Triple 1440p monitors @ 7680x1440p with approx. 144fps.

850 ga, which i had, evga is saying it was known issues with evga 3080 ftw ultra. how much more a 3090. hope yer in usa. call em tomorrow. they will take care of u like they did me.

Pretty sure the GA line has problems with the 3090 due to power spikes that it just can't handle.

Give EVGA a call and they'll likely RMA and get you a different model.

I received my FTW3 Ultra 3090 today. I did a fresh install of drivers. I ran a quick 3D mark benchmark and it went fine. I noticed power draw on the card hit 440watts monitoring with GPUZ. I am not sure if this is normal or not, my 3080 was always around 330w. I see the spec sheet shows 350watts for the 3090. I loaded up iRacing which I play on Triple 1440p monitors and the PC crashes about 20 seconds into a race and shuts the PC down. 
 
I have been running this PC with no issues with a XC3 3080 up until today. No other changes were made aside from installing the 3090, I had to add 1 more 8pin cable from the PSU to the card and a driver install. 
 
My power supply is an EVGA GA 850w Gold. 
 
Is my power supply not enough and is it normal for this card to pull this type of wattage?
 
If its the PSU, what PSU should I go with?

 
The EVGA GA has a well known issue with the 3000 series cards.
 
Call EVGA and start an RMA.

As long as it's not a GA you should be fine.

Yeah the 850W isn't the problem as much as the "OMG SPIKEZ" the 3090 (and to a lesser extent 3080s) do that's the problem.  Hopefully the new unit solves your issue.
 
Did you test an undervolt to see if it solved the problem or not?  Honestly even after you get the new PSU, I would advise testing out an undervolt & see if you can find the happy medium of higher than stock clocks with lower than stock voltage.  My 3090 Kingpin seems to like 2100MHz @ 1025mV - still testing 2160MHz at a higher voltage, but it's basically going to be running at "stockish" voltages to get that clock stable.
The 3090 FTW3 Hybrid I had before ran 2040MHz @ 1000mV all day in games etc with zero issues as well.  That's a good point to aim for, that's Kingpin-stock boost clocks, at 1V, basically a +120 offset with an undervolt, on the regular 3090 FTW3.

Dabadger84
Yeah if you're just dragging the curve down you're lowering the clock probably a fair bit.
 
Basic steps for an undervolt that should be pretty solid:
 
Input a negative offset, something like -60MHz on the core.  Apply it.
Bring up the voltage curve (ctrl+F)
Find the point on the graph for 1000mV, drag it up to where it's level with 2040MHz - click apply, close the curve window.

It should "just work" and result in lower power draw & temps, while giving you better than stock performance.  If it proves unstable, lower the clock to 2025 or 2010.  But I'm pretty sure every 3090 FTW3 should be able to run 2040MHz at either 1000mV or 1025mV with no issues.  That drop from "stock" voltage, which is 1062-1100mV, to 1000mV is a huge drop in power consumption, and lowers the "spikes" that are causing your shut downs as well.

You do have to keep an eye on it though, sometimes the undervolt curve will spontaneously decide to jump up 15MHz after a reboot and that can cause crashing - I wouldn't recommend doing "Apply settings on start up", better to have them saved in a preset Profile position, and verify the clock is set correctly after you load it.
 
You want the graph to look like a flat line from the point you set onwards, ala what is in the screenshot I posted earlier in the thread.

in iracing, capping the FPS will get the power draw down too
I ran a 850mv 1850hz undervolt in iracing at the Cup race in Kentucky last night as was pinned at 144 fps and was only pulling 265w (7680x1440) surround on .
I would give it a try: open Afterburner and hit reset button
Go to clock frequency button and drag it down -300 
then hit Ctrl F to open frequency curve then  anywhere between 835-975 pick a voltage you want to run the gpu at , say select 875 and then click and drag the frequency back up to a normal boost clock rate 1830 hit apply then you will see the line go straight across, I then give it a +200 on the memory slider becuase its free speed on almost all of these cards, open up your favorite stress test or open up Kombustor, and see if its stable, you should be at least -100 watts less
