Hi I am a bit confused. These 6670 and 5670 do not require 6 pin connector(I have). Now it's good or bad ? You may say that it consumes low power. But my problem is, I have a lot or power hungry devices connected to my computer, 2 Seagate GoFlex and a Seagate Expansion. My phone and mp3 player are connected for charging. My CPU is over clocked. (My mobo support 95W) All DIMMs are filled. Wll my mobo be able to power the graphics card?
