Regarding the voltage controller firmware (that limits draw to 1:1.66), it can be updated separately with P1 OR as a package with vBios flashes. The original firmware allowed 85 on PCI, for a total limit of 85+ 85*1.66*3 = 508W when not limited by a board power limit. It is a shame the only way to have this older firmware is via the original 450W bios, so you are capped at 450W total board draw. This explains some more of the user variation as well, between those who flashed direct bioses, those who have launch day cards vs others, and those who used P1 and/or the EVGA update utility. 
 
Regarding the fuses, please use the high res pictures on tech powerup, ex 
or yes BMJets helpful pictures in his shunt mod calculator (XC3 pictures):

THIS!  EVGA can and will fix this... It probably isn't easy. Come Jacob!! We believe!

Which is the opposite effect of more power limit.
If you had a limit of say...550watts for example. You will notice very little fluctuations in your clocks. If your getting for example 2130mhz, as long as temps are okay you will see that value continuously without really dropping or bouncing around at all

Wild swings and instability is a strong indication of power cap

Something really weird is going on with the BIOS switch on my card.  I believe that my BIOS switch has not worked correctly since I got the card on October 30th or I have another problem with the GPU.
 
After I had the card for a day, I decided to try the optional 3090 FTW3 Ultra XOC beat BIOS that EVGA's Jacob Freeman posted here.  I had the BIOS switch on the OC position and flashed the beta BIOS using the program linked in the first post here. The flash worked correctly. EVGA PX1 was reporting a 117% power target. When I checked GPU-Z, it  showed the correct power target and BIOS version.
 
Later, when I wanted to compare that BIOS later to the "normal" BIOS, I shut down the PC and switched to the normal BIOS using the switch, then rebooted. EVGA PX1 showed a 119% power increase instead of 107% with the switch in the "Normal" position.  I thought that was unusual, so I shut down the PC and slid the switch back and forth a few times. The switch seemed to operate properly. When I rebooted the PC with the switch in the "normal" position again, PX1 and MSI Afterburner both showed a 119% maximum power target instead of 107%.
 
Leaving the switch in the "normal" position, I downloaded and ran the program to go back to the default "Normal" BIOS and rebooted the PC. When I got back into Windows and started up EVGA PX1, it showed a 107% power target.  When I checked GPU-Z, it  showed the correct power target and BIOS version.  Then I shut down the PC and switched the BIOS switch to the OC position. When I booted back into Windows, PX1 showed a power target of 107% with the optional beta BIOS already flashed to the OC BIOS switch position. I thought this was unusual. So I shut down the PC, confirmed the switch is operating properly, and booted into Windows again. PX1 still showed a 107% power target with the switch in the OC position after the OC BIOS was previously flashed to the beta BIOS with a 119% power target.
​
After multiple BIOS flashes with the switch in either position, it appears that whatever BIOS is flashed to one position also shows up with the switch in the other position.  I'm assuming the switch does nothing on my card.  I also tried the card in my old PC and had the same issue.  I have tried three different Nvidia driver versions and the switch behaves the same with all driver versions, including the studio drivers.  Both PX1 and Msi Afterburner report the same power limits.
 
When I contacted EVGA support and explained the problem, the support person suggested I RMA the card and set up a RMA for me.  The support person said its either the switch or another hardware problem.  If it wasn't for this XOC Beta BIOS I would have never noticed the problem.
 
TL;DR:
My BIOS switch doesn't seem to work.  Whatever BIOS is flashed to one position shows up when the switch is in the other position.  The same issue happens in a different PC.  The issue happens with any driver version with in PX1 and Msi afterburner.  Support said either the switch doesn't work or the card has some other hardware issue.  EVGA support set up a RMA for me.

Not an opinion. 

I just reviewed the last 400 of 2080 Ti's sold on ebay, a solid 5% had waterblocks, either OEM or aftermarket. 

Of the last 200 FTW3 cards, 9 were hydrocoppers and 6 had aftermarket blocks.

Thanks for looking that up. Thats a data point that helps prove what I was saying. 95% of people, even on high end cards, do NOT watercool. 

Right because Ebay is the right measure to use because every 2080ti ended up on eBay and you you looked at the last 400.. There also people whom took the block off and installed the air cooler back on before selling. What about EKWB and companies who make water blocks? What about their metrics?? A majority do liquid cool their blocks and majority do not...enough said...

A piece of verifiable data was posted that backed my statement.

Please post verifiable data that backs yours. Otherwise ... Enough said....

Not everyone goes to Ebay to sell their cards. Ebay is not verifiable data just because someone else looked up 400 sold cards for you to back your perceived point. Why didn't YOU come up with the data and back your own perspective? Companies that make waterblocks wouldn't exists just like Ebay wouldn't exist without sales. Forums dedicated to liquid cooling have an enormous amount of builds. Toms hardware and other private forums users use to sell items to avoid paying Ebay fees. Again, those are not verifiable results because we do not know who put the stock cooler back on to sell it in "retail like condition" nor we are not accounting for cards sell elsewhere. Why do you think everyone needs to sell their card? I have a 2080ti in my lian case under water and I am not going to sell it. Why? It works well and until it craps out then it will go in the trash.... Instead I built another PC for the 3090 build. You and I both cannot provide full records because you don't have all the facts and I certainly do not have access to company financial records and statistics with quarterly projections. There are also alot of people out there that want to LC their their rig but don't know how and won't take the leap to do it because there is some risk involved and if you are living on a shoe string budget and used last weeks paycheck to buy a new component then taking risks might not be the way to go. This argument is pointless..We are both right in our own minds and I will block which ever card I decided to keep and if you water cool or not I could careless..maybe all your friends are air cooled folk, mine are mostly liquid cooling people. Who knows...speculation right? Have a nice night, I won't be responding back because it isn't worth any more of my time. Do your own homework...

Enough said..

Ironic someone that says "do your own homework" while doing no homework on their own.  Probably best for you to not respond back .. i agree with that since you have no point to be made.  
 
Have a good day yourself.

It's a PX1 bug where the old power target is shown still.

Use GPU Z to see the 500W or 450W max, and then you'll know why I switched to AB again.

Wait,  are you able to adjust voltage settings or prioritize slider in AB?    I can't move voltage bar no matter what settings I seem to do in AB w/ the 3090.  
 
Thanks

So just a heads up the new bios does sustain 500w. Port royal doesn't get it up there consistent gotta use a really taxing program. Furmark or as I call it "hairy donut" gets up there and does not cause spikes to kick it over 500 so it throttles down within seconds like port royal does.

Port Royal is much more taxing than furmark on my system. I can't get furmark to use more than 400w. Power limit still shows as engaged though. Power limit is active for Port Royal as well, but the usage reported is between 430 and 450. 

Do you have Furmark on 8X MSAA?

Yes, running at 3440x1440

All - just to verify the correct XOC 500W Bios for the 3987 card is: 94.02.26.48.F8
The picture above shows a 3987 card with: 94.02.26.48.16
