My 850 Watt power supply has 6 pin pie connectors only. My AMD R9 3900 has female 6 pin and an 8 pin connector. Will cable at the URL below work ?

When going from 6 pin from power supply to 8 pin on video card worries me that won't work no matter what, because 6 pin under powered for r9 390!
Should I try plugging in two six pins to the power supply and the 8 pin to the video card. Then plug one power supply 6 pin to six pin on the video card. That would be 3 connections to powersuply and two to video card? My powersuply has only one 8 pin connector for the 12v motherboard connector.
