The CPU is 12v too, yes.

Unless I'm misinterpreting, looks like that Asus bios held more voltage (suggesting it did pull more power) than the stock bios if that was running the same flavor of Kombustor both times?

The GPUZ pic is cut off. What did the 3rd 8pin read with the Asus bios? You should try one of the other bios I linked in Overclockers (yzonker).

I don't know if anyones suggested it or not, but flashing the bios from a 2x8pin 3080 might work for you. I say this because thats what worked for my 3090. Specifically the XC3 bios. The power reporting was off after that, but the 3rd 8pin pulled the full 150w after that and consumption was somewhere around 500w.

Interesting, I'll try that tomorrow along with the suggestion above for other BIOS. I'll get some pictures of power reporting from each.

As it seems the earlier pictures are probably accurate accounting for my 5950x adding on its power draw above idle from running Kombustor.

It's not the heaviest on the CPU but chances are to boost under the load it's likely adding at least 30w+ to the 12v power package.

 
Not that it should matter, but here is Precision X1 instead of Afterburner. Simply refuses to go above 105% power, pegged at around 400w.
 
Question for EVGA would be what is the point in releasing this 450w BIOS if the card refuses to use it.
 

 
Bump the memory clock up and the core drops/power target drops a bit lower.
 
Highest reading for pin #3, 73w. Rubbish. So the card is basically acting as a fake 3 pin card.

 
So I flashed a Gigabyte BIOS, which totally messes up power readings https://www.techpowerup.com/vgabios/236702/gigabyte-rtx3080-10240-210611
 

 
Overall 12v power still seems to be peaking where it did before.
 

 
Bumped Kombustor up to a higher resolution and I caught a peak of 546w on 12v power.
 
Take 546 - 80 = 466w. But the CPU will be utilised more at a higher resolution so this 12v power spike might not be off the GPU.
 
With all the power readings totally broken with a Gigabyte BIOS it probably makes it even harder to figure out how much power its drawing. Best thing I can look at are the frequencies maintained, and it seems as if they're pretty identical to the EVGA bios.
 
Think I'm just going to wait at this point for EVGA to respond to my ticket. It is interesting though how a BIOS alone can completely break software power readings! Implication being you have to wonder if EVGA have broken their own power draw readings. I don't have enough knowledge around what Kombustor core frequencies other people can achieve with a 3080 at 2560x1440 or 1280x720. If anyone wants to test, cheers!
 
My target is 2160 / 1.05v and +1600 on memory.

Sorry, one more post, most conclusive evidence that the card is NOT drawing power correctly
 
400w standard BIOS
 

 
450w OC BIOS
 

 
Same curve profile in afterburner, barely any difference between the two. In fact, for the bigger laugh, the power draw spike of 403w on the default BIOS is higher than the 401w on the "450w BIOS". Pegged around same frequency. Same iCUE 12v power reading. There has been no increase in the ability for the card to draw more power, even GPU-Z correctly states performance cap due to Power.
 
Will forward this onto EVGA. Either the BIOS is faulty (unlikely) or EVGA has lied about this being a proper 3 pin power delivery card. In which case it's wrongly advertised, though chances are they'd weasel their way out of this saying it's sold rated for up to 400w. Or, it's a total lottery if your card is manufactured better than other people's 3080s and you MIGHT have the ability to draw power correctly on the third pin.
 
Now I understand the total silence from EVGA/Jacob. Poor show given how good EVGAs customer service normally is and how they handled the New World blows up GPUs drama.
 
Given other manufacturers of 3 pin cards do not suffer from this, my conclusion at the moment is AVOID all EVGA 3080/3090 products (other than Ti, apparently they didn't cheapen out there, unsurprisingly). Can this be fixed with a BIOS/Firmware update? Doubt it, seeing as EVGA have done absolutely nothing for around a year now and they seem to be refusing any RMA requests based on power draw. Seems they seriously cheapened out on whatever the controller is that manages card power delivery on the 3080/3090 FTW3. Incredibly stupid move given the FTW3 cards are always some of the most expensive RRPs.
 
I will stand corrected if wrong and/or this can be fixed, and as I said above I am recognising EVGA's usual great customer service. Radio silence on explaining this though is very poor.

Customer service asked for my BIOS version and said they'd check with the technical team, I'm guessing I either won't get a response or it will just be "you have the latest firmware" lol.
 
Of course not blaming CS, they're always friendly and as helpful as can be any time I contact them. Someone in technical needs to answer what is going on here and EVGA have been silent since Jacob said last year he'd look into it.
 
Given comments like this I worry it's a hardware fault
 

My first RMA failed. They sent me a faulty 3090 FTW3 Ultra Gaming again. 
The second RMA has been a complete success.
They gave me a brand new Rev. 3, EVGA 227, which reaches easily 450 W. Even reaching at last 501 Watts isn't a big deal for the card.
EVGA did a great job exchanging the power buggy card. Just look at it by yourself

 
https://forums.evga.com/FindPost/3427435 and unless you gamble on an RMA you'll just have to be happy with your card having a hard power wall where others do not :(
 
I just don't understand if it is something to do with hardware why cards manufactured this year when it was known about in 2020/2021 wouldn't have been a new revision.

Thank you for coming back with additional Information about BIOS.

Please find one of the Stable BIOS available received from Technical Team..

 
BIOS update Instructions (Windows Installation):

•        Download the 3897_Normal_450W.zip file.

•        Extract the files to a location on disk.

•        Make sure no programs are running in the background, and double click 3897_Normal_450W.exe

•        Press "Y" to begin the update.

•        DO NOT TURN OFF POWER OR RESET DURING THE UPDATE PROCESS!

•        After the update, restart the PC.

and let us know the results after updating the BIOS.
 
So customer service is asking me to flash a version of the BIOS that is not suitable for LHR cards and not only that, an older version that by normal means would reject overwriting a more up to date version...

Gotta wonder if +1600 on the memory is inducing errors and dropping GPU performance. Try setting your memory core offset to +500 and see what you get.
