Broken connector on GPU?

[cudlik]

Hello, I bought gpu (asus tuf gaming RTX 3060ti) from second hand for my build yesterday. Today I found out that one of the connectors on PCI E is smaller than others. Is it broken or it should be like that? I cant test it because parts didnt arrive yet. Thanks.

That's normal.

Thanks! I could not find any photos or anything about that. I was a little worried about that. Thanks once again!

Totally normal. It fooled me too when I first got my gpu many many moons ago.

All GPUs I've owned are like that - not an issue.

Thanks, I was worried so I'd rather make sure.

Totally fine. Unless you see obvious signs of damage a short pin in an electrical connector is probably intentional. They're generally like that because the designers of that connection want that pin to be connected after other pins. Wall plugs usually connect the ground first, and USB has two shorter data pins so they're connected after the power pins on the outside.

correct, it's intentional.
AFAIK it's to denote the PCIe lanes, Der8auer talks about it on a recent video.

I don't think Der8auer is 100% correct about how it works. The reason those pins are shorter is so that they connect last when hot plugging. No having those pins shorter than the rest doesn't mean they're not ID pins.

 

I don't have a copy of the standard in front of me, but I suspect they more relevant for a smaller width card in a larger slot (x4 into x16) than they are for larger card in smaller slot (x16 into x4). Host device can sample whether each ID pin is pulled low to determine the lane width of the card before it establishes communications with it; if the slot only has x4 pins, it can't sample x8/x16 ID pins.

 

EDIT: TIL: there's no x2 presence detect pin, only x1, x4, x8, and x16. However, x2 is a valid PCIe arrangement (I have one sitting on my desk right now).
