Why am i missing pin?

[charbel1011]

I got the evga 2080 ti rtx and i just have a question about the cables like if u look at the picture inside the connector theirs a missing metal pin is that normal?

maybe it wasnt needed to provide the full power so they didnt add it to cut costs

have you used the card with that cable yet?

is that a cablemod extention kit?

yh thats an 8 pin for the gpu

I would say that is not normal, while its not going to short anything out the 2080ti is a thirsty boy and if its not getting enough power thats bad

One looks to be keyed (see shape of bottom right outside of the enclosure for that specific pin) for 8pin Motherboard power and another for 8pin PCIE power. 

 

That's just a guess, but they are not keyed the same.  One can fit in one slot, and not the other...due to the shape of the plastic.

not normal? are you sure or you're just giving your opinion?

The missing pin is the sense pin:

 

Not sure why it's missing though unless the connector on the GPU is shorted to the other connector's sense pin.

 

EDIT: Is this a PSU to PCIe cable? Because I just noticed the different keying.

that's the back of my psu. you're right just noticed they keyed. what's that means. it's normal? i noticed the one missing a pin can go to the psu and the one full pin can go to the gpu.

this is what it should look like

i just noticed the shape like somebody mentioned is different like the one missing a pin can go to the psu because it has different shape and the one without missing pin can go to the gpu so i guess that's normal?

As long as it's not a power pin, it's fine.

If its keyed for that, I wouldn't question it personally, I would plug it in...and if it works it will work.  If it fails to deliver power it will boot up with a black screen saying not enough power to the GPU.

i just checked the original pcie cables that came with my RM650x psu and they have a missing pin as well.

Yes, that's the PSU side Cable, wich uses EPS12V Pinout. They are different from the GPU Side and have only 4 Ground, GPU has 5 Ground.

Thus its one Pin missing and one double used.

So i can use this cable on my gpu no problem right that's normal?

Yes, if it came with the PSU you have, no problemo.

BUT: If the GPU has two 8pin PCIe Connectors, use 2 PCIe Cable and not 1!

lmao of course!

Some people are telling me the rtx having doffculties to run with 1 cord with 2 8 pin connectors. I have 2 cords 8 pin connectors am i fine?

Yes, use one cable from the PSU to the GPU per 8pin Connector.

Yes thats what i meant. Please correct me if im wrong. I have right 2 cords seperate and both they are 8 pins. Like they are 2 seperate cords not 1 cord with 2 connectors. Please confirm.

That is correct, 2 unique cables (I call power cords "rails" off the PSU...they used to be referred to as 12v rails back in the day) from the PSU to provide power to each 8 pin port from the PSU individually.
