PCI-SIG now considering changes to problematic 12VHPWR connector


Recommended Posts

The organization behind PCI-Express is considering an engineering change to the 12VHPWR connector, used on NVIDIA's entire stack of GeForce RTX 40 GPUs.

Good, It was a bad design.

Well, thank god. What about all the people that already bought a 4 series? They should get a free cable. I wonder how long it will take before those new plugs matriculate down to the end user in NIB GPUs.

...it looks like my 4090 already has that (option 2 per link above) 😀. FYI, the first 12VHPWR replacement cable has arrived now, the 2nd one (a freebie from Seasonic) is on the way.

In any event, I just removed my 4-into-1 dongle connector for the first time since I got the card almost three weeks ago. I had done a slew of early benchies (up to 575 W actual per HWInfo) at 25 C+ ambient....Looks pristine to me, though I had made sure a.) no sharp twisting / bending and b.) fully insert and 'seat' the connector during the original install.

No, I think the design change is for the cable side of it. Check your dongle and the sideband cables as they go from the connector to the sleeving. I think they are looking to just extend that plastic shroud to the end of the plug whereas right now it ends early and the wires are "in the open".

I am talking about the gap where the sideband cables dock...on some cards, it was/is recessed and thus potentially leaves 'room for error' (the 'before' pic in the drawing) whereby option 2 having "only a shroud extending beyond the plug body". As you can tell from my pic above, it is flush.

Your pic is of the card side, not the plug on the cable. The PCI-SIG before/after pic is of the cable side.

...ahem, obviously, they have to match on the cable end and card side connector (it's a male - female thing...). What I am trying to underscore is that there were different connector styles (some with / without) recess that were harder to fully seat and also left potential gaps. My 4090's connectors worked perfectly so far and are in pristine shape (per pic) even with hard benching and spikes > 600 W because they weren't twisted, and were the right type from the get-go (no recess or gaps). In addition, one set of the new custom cables is already here anyway (again meeting 'option 2', as was the original). So there you have it, my last comment on (various!) 'cablegate' threads at this forum 🤣

Well I promise I am not trying to be dense. Its just my understanding that the PCI-SIG change is only about this part here:

But I was also not aware there were different female plugs on the cards themselves. From my initial look online, they all look like yours (Looked up the FE, Zotac, ASUS, Gigabyte, MSI), so I really don't think the PCI-SIG proposed changes linked in this thread had anything to do with that. It's just the part I circled in red on the plug.
