SATS power connectors

post #1 of 5
Thread Starter 
I'm working on building SATA connectors for a 17 drive server setup and would like to know what the orange wire from the power supply cabling does? the Molex to SATA adapters do not have this orange cable.

I think the orange wire provides 3.3v.

As much as I hate to assume, but 3.3v must not be required if the Molex to sata adapters do not include this?

3.3V is something that was barely used, and you can pretty much count on no modern drive using it. I still wire my connectors for it because I am insane and my [modular] power supply provides it. If your power supply has SATA power connectors, it will supply the 3.3V just to be compliant.

Modern drives pretty much all convert 5V/12V to 3.3v onboard, so the 3.3V line is not necessary. Years ago it used to be.
