Broken pinout PCIe EVGA GeForce RTX 2080 Ti XC Ultra

Hi everybody, this is my first post . I need a little help from all of you.

My big or little problem is that I broke the PCI pinout connector from the pcb... the first one with 11 pins each side before the notch . I want to soldering it back, I downloaded from internet the universal PCIe schematics but I think I have a shortcut because the ground and the +3.3v line have continuity.
In another post I readed that it’s not necessary to reconnect all the pins because the new generation of graphics cards don’t really use the power from the PCIe but from the power supply, I just need to resoldering some data pins.
Could anybody send me a schematic of the PCIe connectors of this graphic card to soldering it and repair it correctly or just tell me if the ground and the +3.3v line really have continuity and which pins are really necessary to solder?

This is what I found on the internet:
Side B Side A
1 +12V PRSNT Hot plug presence detect
2 +12V +12V
3 +12V +12V
4 GND GND
5 SMBus clock JTAG2 / TCK
6 SMBus Data JTAG3 / TDI
7 GND JTAG4 / TDO
8 +3.3V JTAG5 / TMS
9 JTAG1 /+TRST +3.3V
10 +3.3V +3.3V
11 Wake PWRGood

I will really appreciate it.
Sincerely.

Vito Pacillo

Soldering won't help until you physically attach the broken bit to the rest of the card. I suggest epoxy glue. Then think about soldering. Hovewer i don't see much hope for this card. How did you managed to break it so bad??

What a pity….
The pieces look like this after polishing the damaged edges and putting tin on the contacts.
I was hoping to have to solder just a couple of pins, only Data and 3.3 Volts and isolate the copper layers from PCB with some epoxy glue.
The real history is that my brother wanted to make a SLI with another MB and he broke the RTX 2080 Ti…. I almost killed him!!!
My Motherboard is safe because I didn't have the chance to plug it back… Right now, I´m using the integrated graphics from Intel .
What about to isolate the broken edge with epoxy and place a PCIe connector from a dummy board and with a wire connect each pin from its source?

To be honest I think the equipment you are using is doing more damage than good, there are signs of the PCB being overheated. Some of those tracks are very fine. Plus without a printout of the PCB layout there is no way of telling what passes through the board to the other side or connects to internal hidden tracks.

There are professional PCB repair companies, but they firstly may charge more than the card is worth, and secondly may not want to take on something which already has had a repair attempt.

Best solution .. if you brother was SLI-ing with another identical card, keep his and give him the broken one

For what its worth here is a teardown of an evga 2080TI though not necessarily an identical model.

You maybe able to salvage parts but that probably needs a professional hot air desolder station etc to be practical and when would you ever need them anyway?
