Hi guys

I just got a Geforce 2 GTS but I would like your input before I try to plug it.

On the first picture you can see a jumper on the top left corner, near the GPU Heatsink. The current position is maybe the right one, maybe not.
I do not understand how it supposed to be set. Having a closer view it seems someone put it wrongly and burned 1 or 2 jumpers on it.

I'm wondering if I can start it without any of the jumper, or if I should not try at all. Don't want to burn my mobo 🙁

There are two jumpers with two positions each.
Upper row is JP1, lower row JP2. You use a jumper to connect the middle pin to one of the outer pins one each row.
Right now you have position 2 on JP1 shorted with position 2 on JP2. This is not a valid setting as far as the silkscreen goes.

I see, it make sense !
I believe they tried wrong position and that caused short circuit and burned the jumper.
I'm now wondering if it's safe to test this graphic card on my mobo 🤔

If it's just the plastic ob the pins that is damaged (ie if nearby traces and components are undamaged) it should be OK. I would test it if I had it.

Agree ! Worth testing and having them in wrong postions should not have shorted anything out.

Hate posting a reply and have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. 🤣 Second computer a 286 12Mhz with real IDE drive ! After that came 386, 486, Pentium, P.Pro and everything after....

I'm guessing the center pin on each row goes to a different signal connection, probably on that CH7007A chip.
The outer pins on each row are probably +5V and GND, or similar. Setting the jumpers would signal each of those lines with one of those voltage levels.

Somehow it seems the outer pins are the ones that got burned - like somebody tied the outer pins together. I'm not sure how that would happen without deliberate effort.

The fact that the plastic burned means something got hot and a lot of current was flowing. Damage seems likely.
If anything is damaged then hopefully it's just the TV out feature.

To be safe, I'd find an AGP pinout and check for shorts between any of the voltage lines to GND with a multimeter.
If you have a junk motherboard smoke test it in that first.
Otherwise, at least use a good PSU that you trust with overcurrent protection, and which preferably does *not* have gobs of amperage capacity (you want it to trip before your motherboard does).

That was a good guess and advice
So I took my multimeter and figured out the below

So the previous owner put the jumper directly on GND - 3.3V twice...
By the way, I really feel this is a design issue from the manufacturer to put GND pins that near to 3.3V pins without any reason since it's not used in any "official" position

Now I'm just wondering if I take the risk to put this card on a current motherboard I have, or If I can use this excuse to buy another one 😀
