Any ideas on what is going on with the 8-Pin #3 Power draw on my new 3090 FTW3? These were the max numbers on my first Port Royal run on my card. Default settings (no OC), running the OC Bios (same results with the Normal Bios). Power Supply is a 1300 G2. Please let me know if I missed any pertinent info that you guys need.

Thanks!

It's been a known problem with this model card, most people are having the same issue.

If it's a known problem, and most people are having the issue, why is the fix not easier to find?  I can't find anything on how to fix this.  

There is no official fix.

Well, as far as I understand everything, I'd much rather have one of my GPU power cables pulling an extra 8 watts, as opposed to my PCIE slot overdrawing. At least this way if something fries, I think it will be limited to the 8-pin power cable and possibly the PSU, not the motherboard... I'm not sure if the GPU would be damaged if the 8-pin fried, anybody know?

Thanks guys! :)

I think you are missing the point of the problem.  The card is limiting itself to lower performance because 8-pin #3 is *only* pulling 75w when it should be pulling 150w.  

I'm having the same issue with my new 3070 FTW3.  Right now at idle 8-pin #1 is showing 15W and 8-pin #2 is showing 3W. 
 
Running OCCT real quick to load it shows #1: 127.825W and #2 88.546W.  GPU PCIe +3.3V Input Power (est)  is also holding firm at 0.336W.  Is this too low, or is the HWiNFO64 showing the decimal in the wrong place?
 
Before upgrading to 3070 FTW3 I was using an evga 1060 SC and could throw any benchmark at it fine.  That's still the case but 3Dmark has been rebooting to bios collecting systeminfo and at the start of a OCCT "Power" benchmark the computer does the same, kicks me to a black screen and it POSTS like normal.  I was using a ThermalTake iRGB 750W so I swapped in a Corsair RM850 and I'm still showing the same uneven readings.  Thing is I can game just fine at max settings.  the only game giving me random errors is COD Warzone.  Every other game (World of Warcraft, Overwatch, Rise of the Tomb Raider, Battle Front 2 to name a few) play fine.  I left Unigine Heaven running for about 30 mins and had no crashing.  Can the power from the wall make a difference?  Should I switch electrical outlets to check?
 
The other thing is even if I use Precision X and try to OC the Memory Clock or GPU clock by 1 Mhz I get that same reboot, sometimes seconds after I click apply.  Adjusting Power Target seems to yield the same results so i've kept it at default 100.
 
 

I don't get it. All these 3090 FTW3 card use identical design and components. Why is there such a  difference in plug power usage between cards even when the power supply is not the issue. Bad design? Bad components? 

It's not just the 3090's having this problem, my 3070 is acting similar> and Pin 2 drops voltage.
