Best Graphics Card for 400w PSU

I'm currently looking at either an EVGA GTX 550TI or an XFX 7750. Both cards require a 400w PSU. I have an Antec 400C 400w PSU, on newegg it says I have +12v rail 30A. Is this how many amps I have? Is this enough to run a GTX 550ti?

    Yes and yes
  2. Thanks, GTX 550ti it is
  3. i'm sure u can run a 6850 and its better then the 550 ti
  4. how about the hd7770? they use low power
  5. Depending on the age of the PSU, he could even run a 7850 GPU, if he wasn't OC'ing and was just running at stock speeds. I wouldn't recommend it on an older (2+ years) PSU, but it could be done. I'd rather see a 430w or better PSU for the 7850 GPU, but since he's on the 7750/7770 GPU, he should be fine.
  6. get hd 7770 over gtx 550ti
