Hi:

I believe that the HD 6670 will work fine if you replace the 220W power supply that came with your PC for a better one.

It has a 66W power draw, which would place a heavy burden on an old PC's 220W power supply.

The HD 6450 card I recommended for you, while it certainly is not as powerful as the HD 6670, only has an 18W power draw and would be safe to use in your PC as is.

Without replacing the power supply, I wouldn't recommend buying any graphics card that has more than a 40W - 50W power draw in a PC with a 220W power supply.

I wouldn't be able to help you with finding or replacing a power supply.

I only install graphics cards without changing power supplies and I buy graphics cards that I know will work within the limits of the existing power supply.
