The do release power updates sometimes. Don't know if they will though.

Do they void your warrant if you flash a different bios?

This is likely the limitation due to 1) PCI+2 connectors and 2) thermals with the lesser fan and shroud design. I don't see them upping it. This would have been a great candidate for SLI configuration especially 3-slot (my current configuration with dual 1080 Ti SC2 with only 1 slot between them (Hero X). Unfortunately, NVidia is abandoning SLI so this card's purpose is probably best relegated to SFF and eGPU cases.

Does your power slider actually work? Mine doesn't. Leave your power slider at stock and open GPU-Z and run a demanding load. Note the max board power draw. Then max out the slider and re run the same test and again not the load. Make sure you reset before runs. For me the slider is useless and does not increase the power limit beyond 320w with 330w excursions or fluctuations. 

  Mine is the same way. 100% or 108%, performance, power draw and clocks stay the same.

Power slider on XC3 is broken right now,
 
check out this guys video though, about half way through he has an undervolt/clockspeed chart,
 
his XC3 is shunt modded and it goes well above 500 watts at 1 volt
 

We've been trying to bring this to the attention of EVGA reps so we can get a clear answer on if/when it's going to be fixed. As it stands Asus TUF $699 3080 is 350w with 375w max with the power slider. It's also a 2x8pin so no excuse that the "Ultra" card can't do the same IMO. 

I don’t know guys. Just saw a tweet today from Jacob saying the power limit on the 3090 XC3 is only 366W. And that’s the 3090!!!!!! Un less this is a typo but I dunno.

I wouldn’t hold your breath hoping the XC3 get some magic boost with out modding yourself. Looks like this pcb was just designed like a entry card.

I hope my 10 year old PSU can handle a 3080.

they can push it to 375W (117% PL) and still be in spec of the 2x8-pin connectors

The cooler on the XC3 is quite lackluster, at 500 watts it goes to 75c with 100% fan speed. That’s why your not getting any more power limit

Cooler is fine with 130 core overclock with around 70% fan speed mine stays around 65c. Need good air flow.

What holding boost clock does that equal???

You have ultra? Or normal XC3?

Which case are you in if you don't mind me asking?

  If there is headroom, I would like to see an actual power limit increase as well. XC3 3080 owner.  The card already draws 380w and as far as I know thats the limit for 2 8pin pcie connectors at 150w each + 75w for the pcie slot on the motherboard.

That is the limit, 375W for a 2x 8 Pin card.
 
150+150=300 + 75W for the PCIe Slot= 375W.

+1 here
any chance of getting a power limit increase?

Same request from me. Have a XC3 Ultra, peaks at about 330W of power. Should definitely be able to clear at least 360W safely. My card stays at or below 75C at 55% fan speed with max stable overclock at the 330W power limit. I have tons of room to OC more thermally....just no room on the power target. I even ignored raising memory clock and fan speed more to provide as much core power as possible without hard mods (which I do not want to do since I am waiting on stepup to a FTW3). Attached a GPU-z for the duration of the Watch Dogs Legion benchmark.

Just got my XC3 Ultra this week.  It's only pulling about 290-295W and GPU-Z is reporting vrel and vop (both) as the PerfCap constantly.  Voltage is stable at 12.1 on both 8-pins.  What am I missing?
