It's not enough. 22A on 12V rail is too little for that card - you'd be pushing it too close. I'd suggest getting a cheap but quality power supply unit from reputable brands, such as Antec/Corsair/XFX or Seasonic. For example, Antec VP-450 or Corsair CX 430.
It's too hard to find stuff where i live, i'm not american but anyway thanks for helping. Cheers
Watts mean nothing.
