Took a bit of digging but found the old notes:
HP 6-pin to 8-pin PCIe supplemental video power supply cable adapter:
Newest version is option part number N1G35AA = 683867-001
There was an earlier 460621-002 version.
The ATX standard for 6-pin PCIe supplemental power cable is 75W (6.25A x 12VDC).
From the side label of a HP Z620 power supply the same type of cable is rated at a significantly higher amperage than 6.25A. It is rated at 18A....... 18A x 12VDC = 216W. Thus, you can see that HP non-standard approach allows for certain things that a standard power supply would not. And, that is why I truly thiink it might be well worth the effort to find real HP ones, or at least to search out a high quality version that is not missing wires. I don't have a non-HP version to recommend.
