I hook up my 3.5 WD HD through SATA. Nothing detected in bios no matter what I do. Then I remember this
Drive won't power up. New SATA spec supported, Need to stop voltage on 3.3 rail.

Buy these and cut one line don't like molex, fire hazard.
Orange Wire is the 3.3 Volt

Remove it.
But the Grey should be yellow @ 12 V.
Confused.
Cut the Grey. Grey lines up with Yellow on power supply and that is the 3.3V.
Yup works.
Even with my brand new power supply need to do this.
