Hi, im leaning towards buying the evga gtx 650 ti boost superclocked 2gb, but i've read somewhere that it needs 24 amps on the +12v rail. I am currently using and hoping to still use my AcBel ce2 500w psu, but im not sure if it can supply the 24 amps required by the gpu. The psu label says it has a max load of 17A on +12v1 and 19A on +12v2. I know my psu is not that good but i would like to use what i do have atm, im just not sure if it can supply enough power for the gpu that i am looking to buy.
