Powering up PCI-E riser

[czr]

Hello there

Need an advice which pins on PCI-e riser should be connected (soldered) to an external 12V power source.
Are these six pins marked in the attached picture correct?

I guess @Aibohphobia and @QinX know something

Answer would be better than advice
Your links do not contain any information about 12V pins localization on PCI-e socket (on soldering side).

They tell you explicitly what pin does what, and assuming you're soldering you should have a multimeter on hand for continuity testing. We can't see all the traces so that's the best the mortals among us can do *shrug*
