What is the best gpu i can get on a 300W psu

Hi. Wich gpu is the best one for a psu with 268w max on the 12v rail and 19A max on the +12v and 0,8A max on the -12v dont know anything about the 12v rail + and -

Considering a radeon 7750 or a 7770
Will go for a 7770 or better if it has the power. If you need more specs from the psu ill help you out.
This is the full easy list of the specs i picked up:

300W psu
268W max 12v rail
+12v 19A
-12v 0,8A

Please do answeres thats about this and do help me. Keep it inside the barriers. I just whant to know wich gpu i can go for or if i can go for something better/worse without blowing my psu. I know i should get a better psu but right now i wont do it. So i whant to know what i can use for it, wich is the best gpu to go for or if you know a better one with the same or less power consumption

Btw. Looked up some other forums and they say the 7770 would run fine. Its only drawing 80w at load. I dont know the amp draw though.. Ive heard it does make difference if the amp from the pau is low or high.
