EVGA 3080 xc3 ultra is very little ultra. This card has a big power problem! It basically takes too much current from the pcie and too little from the 2 PSU connectors. In practice it goes into Power limit before 320 w when it should reach 340 \ 366 instead. It is a big problem for the boosts which are limited, it is also a problem for the safety of some motherboards as the power spikes on the pcie could put stress on the board and other components on it. EVGA worked very badly, I hope it can be resolved soon with a BIOS upgrade otherwise on January 31st, fortunately limit time given by Amazon for purchases in this period , I will go back it immediately. For now I set limit tdp to 300W for safety to avoid doing damage. I was from a very good Turing EVGA, but with ampere they made quite a mess.

as you can see the pcie connector It already delivers 67 w And this is already the maximum it can deliver. I'm not the only one with this problem, but it's also true that not all cards have it the same way.

I cannot see your image (need more then 100 posts)
PCIe standard draw is 75W max.
So your power draw is bellow max.

The PCI standard is 75 , but 67 from 12vand 8 from 3.3v This the image https://i.postimg.cc/prjX...0201121-123006-442.jpghttps:// i.postimg.cc/prjX...0201121-123006-442.jpg

I have an xc3 ultra. There is def nothing ultra about it. Its a black with backplate and 30 mhz. Why there isn't a backplate on a 700 dollar card is a joke to begin with. Last ultra at least we got a beefed up cooler. It's probably the most unjustified 80 dollar premium over the base I have seen evga do to date. Same goes for the FTW3 ultra pcb design at 109 and 300. I have the 80 FTW3 ultra as well, and I am getting the KPE 90 as well. I have bought products from evga every graphic generation, but I will call it as I see it. The FTW is not what it use to be with the 20 and 30 series. On the 3090 FTW3 which I owned shortly, the 300 premium over the FE for that kind of of pcb design is extremely disappointing to say the least.

It must be activated with a particular procedure, you can find plenty of guides on the internet. But it has nothing to do with the problem If you turn up the tdp, and fortunately it does not happen because the limiter works, you risk breaking the motherboard.

This is the command you will have to run to show the ultimate power plan if it's not showing. Ran in the windows 10 search bar. powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61

2 x 150W (8 pins from PSU) = 300W even 67W from PCIe brings total 367W I have no idea about your rig spec so can't see your problem. Images are not loading btw.

The problem is, it doesn't go beyond 315W 320 at times.Tried with everything, it doesn't work. Because the consumptions are badly distributed they take too much current from the pcie and arriving at 67 rightly stops. Should the opposite happen, they should be limited to 150wx2 on the connectors and then Just in case use the pcie a bit. I'm not the only one to have this problem otherwise I would not have opened the post. I would appreciate a response from an EVGA technician, I have also opened a ticket.

It's irrelevant. Red herring. Ignore these suggestions. Makes zero different to the subject of this thread.
ASRock Z77 • Intel Core i7 3770K • EVGA GTX 1080 • Samsung 850 Pro • Seasonic PRIME 600W Titanium

The problema il clear , EVGA engeneeers , wrong to calibrate where the card draws power. it takes too much from the pcie, and when it reaches the limit, which is 67W on 12V, it stops , so as not to ignite the pcie socket of the motherboard. Waiting a fix from EVGA ! Or at least a response from their support.

Mine goes up into the high 300s with a slight OC. But I have a high end PSU and MOBO. No issues what so ever.

My Ultra is very Ultra IMO.
Boosts to almost 2000mhz with no OC at all and doesn't budge. Also only draws about 40-45 watts from PCI-E slot according to GPU-S. Runs super cool to boot. I honestly couldn't be happier all around with the performance. Now my only worry is if it will develope issues like soooooo many cards seem to be around this forum.

man, consider yourself lucky... just by saying that it draws only 40/45 watts from pci-e slot i can say that your model is not affected by the issue that all others are having, and... let me guess, it has the red lip at the end of pcb, right???

I am running into the same issue with mine, I have my card water blocked and my temps never go above 50 C atm cuz of winter time. Card cant go over 320 Watts at all. Please let me know what EVGA's reponse is to you

Wonder if this is a problem more common on the 3080 XC3 Ultra. My 3090 XC3 Ultra draws nearly 360-370W constantly and hits as high as 380W. The card pulls up to 156W per 8-pin and up to 73W from the PCI-E slot. And this is with it undervolted/overclocked at 1995@950mV (+135 offset), 100% stable.
