Do I trust this Corsair Type 3/4 Pcie Cable?

hi

really hope someone can give me a clear answer on this one. Am using a second-hand Corsair 750w psu (TM) for almost a year now and all is good but wanted another pcie power cable as it only came with one and heard to use two cables from psu if gpu had two 8 pin connectors required. I have ordered and received one but when I checked the pin layout compared to the existing one plugged into the psu I notice that the 'empty' pin in the new cable is different - the new cable its 'bottom-right'.

Weirdly I checked the Corsair site before I bought cable and it says 'type3/4' are same and looking at other sites with pictures I can see the new cable I have bought is the same as everyone is selling but why is my existing pcie power cable layout different to my new one?

I dare not connect the cable to my psu until I feel it is safe to do so.

Thanks for help.

It appears that all the pics of pcie type 3 or 4 cable the same pin layout as the one I have just bought but the one already fitted to my psu is the one that's different?

To clarify things a bit. The psu is a Corsair TX750M and as was bought in a second-hand build it only came with some cables; presently I only have one pcie power cable connected to my 2080 and was wanting another as heard it is better to use two separate cables than just the one.

This is a picture of the pcie power cable that I have bought (connector that goes into psu)

This is (a bad) picture of the present pcie power cable (connector that goes into psu)

As can see the pin layout is different with the new cable that the existing one. The wird thing is that a couple pictures I have seen of corsair pcie power cables is that the layout is like the new one that I have bought rather than my pre-existing one!

Can anyone confirm the layouts to be okay and the same as theirs.

Thanks again.

I think the second pic is not a PCIE connector, its a peripheral connector for sata or molex power [EDIT or possibly CPU cable]

No, its to a pcie power 2 x 6+2 as is the first cable.

Thanks for replies.

Seeing the pin layouts being different has so far prevented me from using the new cable - I presumed they would/should be all the same layout.

Using the one cable has caused no problems so far; reading posts recently where people have had gpu problems and a common suggestion is to run it on two cables rather than one. Would love to know if it has any difference to the gpu.

I shall continue to run the 2080 on the single existing power cable for now.
