bro it will take me around another 2 months to get a good amount of money,so iam thinking that I shall buy a graphic card and next month I will buy a good psu and mobo together,but is my psu enough to handle gtx 660 non ti?
If that psu can deliver close to it's rated power it is OK.
Coolermaster is known to lie & exxaggerate their specs
tho. You will prob be ok as neither of these cards actually require
a 500w unit.
