[DC] Why is Superman so powerful?

From what I know of Superman, his powers are virtually limitless. He has been portrayed as capable of just about anything. But the source of these powers is, AFAIK, that he's a Kryptonian living on a planet with a yellow sun.

Is that the only thing that marks him out? Are other Kryptonians (like General Zod or Supergirl) equally powerful? Or is there something special about Superman?

Yes, any Kryptonian exposed to yellow sunlight will become as powerful. Supergirl is supposed to be stronger than Kal El, because she was bathed in yellow sunlight while in transit, but she's not as experienced, and doesn't make particularly good use of her powers.

Krypton was a potentially universe-conquering race; their xenophobia and retreat to Krypton was for the good of other civilizations, not them.

The *entire* Green Lantern corps, for example, shits a collective brick at the prospect of taking on a single Kryptonian.
