  1. It should be OK. The GTX 660 does not consume much more power than the 6770.
  2. Am using my EVGA GTX 660 SC on GX550 working fine for me it will be also good for you then :)
  3. thank you very much but some people saying to me what my psu is not branded and it will burn my pc can you post some pictures of your power supply output table so i will compaire with mine
