I think i get 1-2 frames less after upgrading from my old 250watt psu to 500watt. I am not sure actually but can that happen?

1-2 fps is within margin of error. You are fine.

Also, just because you doubled the wattage does not mean you used a quality power supply. The PSU could be causing problems but I doubt it considering you are seeing a 2fps drop. Its likely fine.
