What about P5 3988 Hybrids?  I have 2 here that both have severe power balancing issues.
 
XOC Bios, Power slider set to max running port Royal.
 

Just fyi I sent the requested information in to the email about my 3090 power draw issues and the response is only to ascertain if an RMA is warranted. It is not to be able to get a new better BIOS.

Well, at least there is an official acknowledgement that it is an issue. Thanks for sharing!

I have the same exact problem 8 pin 3 has low power usage.

The email also states too that an RMA replacement may not fix the issue. Said they make no guarantees. And we are only allowed one free RMA replacement for this specific issue. So an RMA may be a waste of time.

I interpret this as them stating your OC results aren't guaranteed however they recognize the issue we experience is related to power delivery.  EVGA has never (to my knowledge) guaranteed a specific level of performance like boost clocks or the like but do expect the cards to operate within their power scope as it pertains to the relevant bios. 

• There are NO other benefits that should be expected by replacing your card.  
• The new replacement card will already have the XOC BIOS applied to the secondary BIOS position.
• There are no expected changes or improvements to the stock running speed, boost clock, or stock overclocking on the default BIOS. 

Edit:  Emphasis added by me.

I have that card that Jacob mentions, so it seems that there will not be a BIOS solution at all as from what I understand and read what you guys are posting...

Since the XOC BIOS will already be loaded on the RMA replacement, I'm guessing EVGA is manually testing 3090 FTW3s to see which ones aren't affected by the power balancing issue and sending those as the replacements. But again, that's just my guess.

Yeah at idle I'm around 28C as well. This was using the 1000 watt kingpin bios set to 540 watt. My card hits voltage limit at 500 watt. With the XOC 500 watt bios I usually sit around 450 watt usage. I went back to the XOC bios as the Kingpin 1kw bios does not play nice with the nicehash miner.
 
  

But my one is 28C when it's fully loaded...

Huh are you using a chiller along with liquid metal paste? Not sure how 28C is possible at full load ~500W without exotic cooling.
 

OK so to summarize, the power balance issue is revealed in one of two ways:

1. Low #3 8-pin input power
2. High out of spec PCIe input power

Eg. of Low #3 8-pin input power;
Afterburner 107%
GPU Power: 400.9W
GPU PCIe +12V Input Power: 73.1W
GPU 8-pin #1 Input Power: 117.0W
GPU 8-pin #2 Input Power: 107.3W
GPU 8-pin #3 Input Power: 104.6W
 
Eg. of High PCIe Input power
Others have mentioned values above 90W here
 
Anything else?
What sort of power delivery spread would we expect to see?
