  1. Does your power supply unit have a combined +12 Volt continuous current rating of 18 Amps or greater?
  2. Your PSU is sufficient enough to handle that card
  3. the recommended watt for the 6670 is 400+ watts. I have this one at home. You have a sufficient amount
  4. Even a 250 Watt power supply unit like the Seasonic TFX SS-250TFX and the SFX SS-250SFD will work. It's not the power supply's total wattage that determines whether or not the power supply is capable of properly powering the system. Always look at the combined +12 Volt continuous current rating of the power supply.

    There are generic low quality 400 Watt power supply units out there that are unable to provide enough output current on their +12 Volt rail to properly power a system with a single Radeon HD 6670 and yet its 400 Watt label would indicate that it meets the power supply requirement specified by AMD.
  5. that means no need to extra power supply to the 6670 Card.

    I hv seen that ATI RADEON 6670 has no extra power connector unit
