Ive recently moved my pc into a new case, 1 problem i dont have enough molex power cables for the fans/hard drive/dvd-rw. Can i use sata power cables for the hard drives instead? they have the sata connection just not sure if i can use it plus i have a load of spare sata power cables spare. There both western digitals i think
If your drives are sata drives then certainly use sata connectors which will free up the molexs. AFAIK only the older Western Digitals have dual power inputs.
