So do the SATA connectors that come off my PSU plug into my mobob or my HDD/optical drive
Yea cause I got like 7of those 4-pins with 2 of them having the blue plasti thing over it. So are you Saying the the 4-pins(with blue coer) plug into my HDD and my Optical Drive and the other 5 are for my fans?
If you are connecting your optical drive and HDD to your motherboard via Sata cable, then the sata power connectors will plug into the drives. The connectors are so different that you can basically go off of, if it looks like a spot where a certain connector should go and the connector fits without too much force then thats the right spot.
If your fans are powered by molex connectors and not special adapters then yes they are for your fans.
