In modern PSUs, the 12V rails power everything that uses a lot of power, so that's the most important thing. You seem to have two 12V rails, cabable of operating at 12A and 16A. Since this is a poor quality PSU, I'd say you won't get more than 25A (absolute maximum) combined.
What exactly do you want to use the PSU for? I can tell you if it will suffice.
I asked on here before about running a GTX 750 on this, since it will only take another 23 watts when replacing my current GPU, and GTX 750 requires atleast 18 amps.
