i have a gtx 770 evga sc, i also have a cx500 psu, i bouight it off cyberpower and it said i needed a 500w or greater for my system so i got one. later i found out that my gpu required a 600w or greater. am i damaging my gpu? what should i do? ive noticed that my performance in bf3 has dropped, i have never gone under 60 fps until recently. And if it is broken its been past 30 days so id have to pay for shipping, now why the hell would i have to spend shipping for something they didnt tell me about and that i spent 1300 bucks on, and im 15, it took almost my whole life to get that money
