1. I know there are 4-pin to SATA power adapters readily available, but do they work both ways (ie: SATA to 4-pin)?? 2. Also, would there be any negative effects to having a SATA power cable from the PSU going into a 4-pin adapter and then back to SATA?? Reason: The breakout cable for my RAID card has the power built into the cables. It uses 4-pin inputs and then plugs in via SATA, so I would need to convert my SATA from psu power cables to 4-pin then they would convert back to SATA through the breakout cable. ..Or.. I just buy a breakout cable without power and I wouldn't have to worry about it, but thats more money. EDIT: I got this respose from an engineer friend but it is not a definite no: anyone have any input?
