Is there any ampere requirement for Power supply

[nawazish1]

Hello guys I have a question that is there any Ampere requirement for the power supply to power two GPUs
one more question is how many watts are required to power two 6950 at stock for scrypt mining.

The various rails/power connectors will be rated for different Amperages, but Voltages and Watts are more important.  There is a chart on the side of the PSU's packaging box that will list Volts, Amps and Watts for each rail.  In your case, a 750 Watt power supply should do the job.

If you think you will be mining with those video cards 24/7 it is a good investment to get a high-quality, 'gold' rated power supply. It'll save you power costs, have less likely chance of burning out, and even if you stop mining it's just great to have one of these things; it'll last you a very, very long time.
