Is it safe to use a molex to sata cable that is crimped not moulded to power a shucked drive? (alien.top)

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.

crimped or molded, doesn't really matter. it's only a problem when the conductors in the molded plastic get hot enough to drift till they make contact. if you're mindful of your currents, it's fine. molded simply provides a little channel for heat to escape.

you're not gonna get 3.3v from a molex connection for this. that's only available on the mobo connector and sata cables directly from the psu.

the 3.3v fix involves taping off those pins on the hard drive so this fix isn't really necessary. I've yet to find a sata drive that requires 3.3v.

so yes, it's safe. just don't go crazy with daisy chains and trying to draw too much power off one molex or sata power connection.

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?

What is this 6 pin you speak of? Are we talking modular psu or OEM? The only molex I'm concerned about is the one that carries 12v, 5v, and a couple grounds. The only 6pin I'm aware of is normally for a GPU and that only has 3 12v wires and grounds.

Maybe some pictures will 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

Ok. All that is fine. There's no 3.3v wire to worry about. The drive won't miss it.

Cool, thank you for your help!
