Cool, thank you for your help!
Modular PSU, the 6-pin (but only 4 are used) goes to the PSU. Here is a image of the cables. https://imgur.com/a/C95FjRi
So I should be fine with the current configuration ofPSU 6-pin to Molex, and then Molex to Sata 3.3 adapter that connected only to this one drive?
Good to know, thank you.
The molex cable doesn't have the 3.3v pin on the psu side. So I should be ok?
I don't have kapton tape or want to cut wires as I don't have a spare sata power cable. However I do have a molex power cable and a molex to sata 3.3 adapter that came with my Seasonic Focus GX-750 PSU. It only has 4 wires and does not contain a wire for 3.3v power. The sata connector is crimped and not moulded. My shucked WD180EDGZ-11BLDS0 seems to require the 3.3v pin fix.
