Older models did not have that problem. I've had the exact same problem as you, so ended up selling, no RMA wil fix that. You can check the w with an external device to really see it.

My original Card was exactly the same and it was an older Non LHR 3080FTW3....exact same results as yourself....running Kumbuster it would get up to 425w max.....it has been mentioned on here numerous times that the Board Power Draw shown in GPU-Z is actually 25w or so less than reality.
As for PCI-E Power #3 being low, as in 1/2 of number #1 or #2 ....perfectly normal for these Cards...google power balancing issue for more details.
My newer 3080Ti LHR Card is exact same with power balancing issue over PCI-E Power ports....#3 being significantly lower than the other 2, although this Card will reach 445w in GPU-Z, so assuming closer to 500w...
Someone earlier had mentioned that this didnt affect "older 3080 Cards", well I can assure everyone that it absolutely did ;)
 
Try running Kumbuster with GPU-Z running in background then check max board draw...n let us know what you get.

Once you start down the rabbit hole you start questioning your hardware based on random opinions of some who have nothing to do with the manufacturing aspect. You don't need to pull 450w - sure, it's cool but then you get lost in the idea your product isn't performing and then you start to second guess which we are one of the only AIBs who encourage that such as overclocking and some like to undervolt but it's not the end all be all. My opinion - everything looks good based on your screens. There has always been a fascination about power draw with these cards. Basically, MOAR POWA but your benchmarks look good.

Memory starts crashing Time Spy at 1100, so 1000~1050 seems to be the best I can do.

Core clock starts crashing at +165, so I presume if I want to attempt to push more there I would need to play around with the voltage curve. I did that with my 2080Ti (used a curve at 2100 1.093v) but for now I think I'll just stick with +150/+1000~1050.

GPU score above improving likely needs core going higher, not memory.

I'm surprised at how well these 3080s watercool, but then again this EK Block also has a nice nickel backplate with thermal pads for some additional passive cooling. My 2080Ti Corsair waterblock just had a standard backplate with no cooling properties.

(I abbreviated your post)
 
Test with even lower Memory OC to see if performance increases   ... crashes are an outright failure of OC.  These new cards will use "error correction" .... so performance can suffer - before crashing occurs ..(edit) If you push the RAM too hard
 
NVIDIA Boost has the last word in your boards final numbers, been that way for several generations.
 
As long as your MHz meet the advertised minimum it is Fine; after that it is the luck of the silicon lottery
 
Getting Max performance before hitting the Watt limit is a Good thing in my book
 
EDIT:  added = (edit) If you push the RAM too hard - for clarity

This is what a good power balance on a 3080 FTW3 looks like:

Yeah that's perfect, so my card is faulty then? Given this is a "2022" model on the basis of being shipped out like a month or so ago, that is incredibly disappointing if EVGA haven't fully remedied something people have been complaining about for well over a year.

Not sure about your card.  The readout from the card above is from literally the first batch of 3080 FTW3 Hybrids in the US, Dec '20.

I would like to say pre-LHR then, however this forum has quite a few pre-LHR owners with the same issue.
 
I seen Jacob was supposed to give an update on the problem in... 2021, and never did, so it looks like it could be a sweep under the rug from EVGA and a "Did you know we now sell Ti cards featuring 450w out of the box!".
 
Pin 3 going to 120w is the main difference in that picture above, my pin 3 is stuck at like 75w.
 
At this point I'm just going to see what CS say in a reply to a ticket and then thanks to your picture above I can further press them on why some 3080 FTW3 Ultra will go to 450w.

Doesn't your HX1000i have Corsair Link Digital support? Doesn't that have an integrated current/power meter?  Check that for each power port.

iCUE is pretty decent for showing some info
 

 
Would it be the 12v power I monitor?
 
A core frequency of around 2160 is basically where a card will tap out with a 400w max power draw. So that lines up with the wall I have. I can't seem to get over 400w, therefore, trying to run above 2160 is basically a no-go with any serious load.
 
 

There is no way your card is doing THIS without the full 450w:
 

 
It's likely just under reporting.  Watch the "12V power" in the Corsair readout at idle vs. maxed out in Furmark, and subtract the change in CPU power use.  I bet its a 400w+ difference.
