[URL] Safe connections would use 2X sata power for each 6 pin You should have ONE  cable with 2 6 pin that goes into an 8 pin. The other 2 X 6 pin to 8 PIN comes from 4 SATA Power connections. I'm getting the 1300w unit for mine so I dont have to worry that it will DIE and FRY. There are lots of separate extra Sata power connections inside. DO NOT BUY a single sata to 8 pin. Those are not safe. cutting corners on safety to save $12 can cost you your life when it burns the house down.  4 wires is minimum safe margin for the connector. This is because each 6 pin is rated at 6.25 amps and each 8 pin has a 12.5 amps rating for 12v [IMAGE]connectors [URL]   [URL] [IMAGE]Each wire has a max current rating which is why do DO NOT just double up what you have the other way [IMAGE]USE THESE WITH AN ADAPTER
