Seriously Nvidia?? "12" pin power on 3060ti FE

I got my FE 3060ti today, check out the "12" pin adapter, it only has 6 pins populated. Now my question is, is this a special adapter for the 3060ti or is the 3070/80/90 the same? Any owners help me out here? I'm worried about ordering a third party cable now as they might be different for this card as opposed to the higher end ones. I will probe them with my multimeter tomorrow to see what pins are ground/12v.

Maybe 3070 uses the same one, but 3080 and 3090 doesnt

Thanks for the info, damn it there's at least two seperate adapters then. Maybe the custom cables would work but if a ground and 12v are swapped it will fry the card. I'll have to ask the cable mod guys to see if they are aware of this, don;t want anyone not realising and killling their card.

 

There is a warning in the box not to use third party adapters....Now I see why.

I'd guess each half of the 12-pin corresponds to an 8-pin on the other end, so single-8 cards get half the pins and dual-8 cards get all of them. You wouldn't want to run a 3080 off a single 8-pin anyway, so it makes sense.

So I'm assuming the 3070 is the same? Does that have a single 8 pin to 12 pin? It's still concerning though. Why not have a six pin for the 3070/60ti and a 12pin for the 3090/80?  Cost??

Cost for sure.

Instead of ordering the parts for the 12-pin socket, AND for the ATX PCI-E 6-pin and 8-pin sockets, they can just bulk order the 12-pin.

 

That and they don't need the R&D to redesign a PCB for the RTX 3060 Ti.

Just use the same PCB layout as the RTX 3070.

Makes sense I suppose as the 3060ti is just a cut down 3070.  Makes me wonder if a 3080 adapter would work on a 3070/60ti. I'm certainly not willing to try :P After looking at the cable mod place I was thinking of ordering from, they have seperate selections for the dual and single 8 pin to 12 pin connectors. I have asked them about it just to be sure though.

 

Also makes me wonder if any adapters were put in with the wrong GPU? A dual with a 3070 for example.

I'd expect a dual-8-pin to work fine on a 3070 or 3060ti, as I believe the pinout is just one solid row of 12V and one solid row of ground. One of the 8-pins just wouldn't supply any current.

Well I'm gonna get the multimeter out tomorrow and check that hypothesis. That's the standard on the output of an 8 pin and 6 pin, plus sense pins on the 8. Different PSU makers have different PSU side connections. (I know people who have fried GPU's using the wrong modular cables)

 

Has there been any official confirmation why Nvidia decided to go 12 pin instead of dual/single 8? Seeems like an added expense, one that the board partners obviously didn't want to share.

 

Thanks for the feedback and info people...This forum is great!
