Isn't the newer 12v6x2 connector supposed to fix this? I think nvidia has been putting this on all new GPUs .
yes, the 12V6x2 lengthens the power pins for more connection surface area, while also shortening the sense pins to prevent any operation at all if the plug is not fully seated. The updated standard seems to be doing better so far.
Do you need both a new cable and the updated gpu pcb port to take advantage of this?
The primary changes have been to the male pin connector which exists on the GPU or PSU side not the female socket connector which exists on the cable. So the cable is fine but the gpu is not.
It could likely be replaced on thr GPU by a good repair shop. The PCB plug is a quite easy solder job all things considered.
Don't you have that reversed? Isn't the cable the male inputs? You have to slot them into the GPU/PSU.
well, the plug standard is a bit confusing.
The "female" mechanical socket on the motherboard contains the MALE electrical contacts. And the "male" mechanical plug on your cable contains the FEMALE electrical contacts. This way they slip inside one another without exposed contacts.
I was talking about things from the electrical point of view since that's where the only spec modifications were made.
Plug/cable end.. note the electrical contacts are hollow tubes (female)
Socket/PSU or GPU end.. Note the singluar male pins in the holes.
Yea that makes sense. Thanks for clarifying. It seems some PSU makers also have new 12v2x6 cables? Are you sure they didn't change the cable at all?
Doesn't seem to have changed the cable at all, no. The only mechanical changes I can find anywhere, and I've looked quite a bit, are strictly to the electrical male pins on the device side to improve contact on the current carriers and shorter sense pins as to prevent operation if the insertion is even a tiny bit incorrect- everything else was kept the same as to maintain mechanical compatibility between the two specs.
PSU makers rebranding cables as 12V2x6 is probably just a marketing/keeping up with the spec thing. It should also mean that they changed the pins on the PSU side as well for modular power supplies.
Gotchya. Yea this entire thing is incredibly confusing and frustrating. This entire standard is a fucking disaster. Whoever designed this bullshit should never work in the industry again. I hope the 12v2x6 tweak is enough to finally get past this so people don't have to worry about their fucking PCs catching on fire.
