I dont wanna really save up for an expensive card i want to wait abit for the maxwell nvidia cards for next gen gaming, I have the Sapphire HD 7870 xt I really want to crossfire it with the same gpu i currently have a corsair tx 650m an is this enough to support 2 sapphire hd 7870 xt crossfire setup? because if i were to buy another psu i would just rather buy a brand new gpu as it would be around 500 dollars over anyway any suggestions?

on saphires site it says that a 600w psu is suffiecient for cfx

your stock cpu is 77w
your mem/chipset no more than 84w
your cards should consume around 144w a peice

couldnt find your specific card but these 3 are the ones i used to get power draw from

this is 449w on 12v rail
your psu pushes 648w on 12v rail

you should be fine even with your over clock
