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?

Do these have the 3.3v pin issue?
