Powering a PC SATA Power Conenctor

[DW1961]

How would I g about powering an SATA power connector using a bench power supply?

What I want to do is power a 5V LED controller so I can test computer ARGB lights before installing them. Unlike 12V RGB lights, which just require  + and -, the ARGB requires a signal to turn them on. So, I have to get a cheap controller, and then power it. All of the controllers HAVE SATA connector. I don't have a problem just cutting the SATA connector and using a + and - connection from the bench power supply, if that is all that's needed.

Connect negative to the black wires and +5V to the red. If you need 12V, that's the yellow.

SATA has 12V lead? What uses that?

Older SATA 3.5in drives use the 12V supply, though more modern ones do not. SSD drives use 5V only, and pretty much nothing uses the 3V3 supply, deriving it from the 5V rail instead. Optical drives also use 12V.

Get a basic  molex to sata adapter cable, cut the molex connector and connect the wires to your power supply. Example cable : https://www.amazon.com/12in-SATA-Power-Cable-Adapter/dp/B0002GRUV4/

You only need the 5v and 12v wires ... red is 5v, yellow is 12v. Blacks are ground or negative.

Rubbish. 3.5" drives almost if not entirely exclusively use the 12V rail for the spindle.

HA!

It's been so long since I used a mechanical drive, I'd forgotten about the 12V sata purpose!

Could I  just cut one side of an SATA connector off and use the + and - wires with the power supply alligator clips?
