3080TI 8 pin giving unequal watts to card

[botwright]

Hello everyone so I just installed a used Gigabyte 3080ti in my system and it's having some issues. Upon running some benchmarks its score is way below where it should be on 3Dmark. During benchmarks and idle, I have GPU-Z open to monitor the sensors. The voltages for both 8 pins are both 12v. However, 8 Pin power #1 gives power reaching up to 150W underload while 8 Pin power #2 stays at 4W during benchmark and idle. This causes the Clock speed to drop to the low 700s. I've tried it in a new rig as well. Also, we are not using daisy chains on this system. The power supply in both systems is 1000w as well. Also, check where the 8pins go and there seems to be no damage. Important note: The previous owner replaced the GPU fans and I've heard to open up the card, unplug, and replug them back in. Also, temps on the GPU are fine.
The next step right now is to open it up and replug fans and DDU the drivers. Lastly, I did an OC scanner on MSI afterburner and received a response. Below is a 3D Mark score report, and GPU-Z screenshot (not during benchmark but gaming).

What CPU/board/RAM is it paired with? What model PSU are you using? The card should pull ~75W from the PCIe slot, putting you around 200-225W... which is still much lower than the 360 or so that a healthy 3080 Ti pulls.

This means basically nothing, it just didn't find a stable OC and the limit was voltage, which is always the case on these modern cards as Nvidia does not let you up the voltage much.

Somewhat sounds like he rather damaged the 2nd input somehow and downplayed it hoping you wouldn't notice.

Yeah, just DDU the drivers and the same issue. Time to open it up to see although no visible damage to the ports from the outside.

Is there a way to replace the port myself?

[Kilrah]

Would need to figure out what's wrong first... almost certainly not the plug itself but some components down the line.

First of all ignore the MSI overclock tool , I think I got it to work once in the half dozen cards I've tested on it.

 

Can you actually try running a daisy chain from the working pcie cable and see what happens.

 

Can you post a screenshot of the sensors under load aswell , it looks like you posted the idle.

Has the card been shunt modded?

Check the pins inside that second power connector. Gigabyte had issues with the power and ground pins inside the connector pushing out on the cards that have a shorter PCB. (Eagle, Aorus Master, Vision and Gaming).

They used a special pigtail and just had issues with the pins staying connected. Picture below is for a non TI, but the power connectors are the same for the ti.

The pins look fine from the outside are you saying to open it up and take a look?

If those pins on the graphics card side look fine(but all of them. Not just specifically those three)then I wouldn't take the card apart to make sure. 

If you do take it apart for some other reason then there's always some checking that can be done.

Here’s pics of the ports on the GPU

Those don't look messed up.

What about your GPU-Z sensors under load? The link is cut off and broken.

What’s the board power draw when your perf cap reason is power (green)

Theres some other minor things there I’m not a huge fan of

Honestly not too sure what a perf cap is. How can I see what the power draw for that is?

Okay disregard my previous messages I’ve figured it out.

When it’s green board power draw is 224w

heres a photo I took during a benchmark

At least these 2 look twisted, something's wrong there. Could be melty on the other side.

What’s a possible solution to this? Twist them straight?

Need to take the card apart to see how messed up the back of that (and the rest) is, then see from there...

Sounds good will do. Thanks.
