My PSU is 400W.It actually came with my I-ball cabinet i bought. I don't know the exact model name.its about 3 yrs old. The case is i've bought a Zotac GTS450 amp edition card. Can i run it ?

😀 
simply buy a 750 watt PSU from cooler master or ANTEC or cosair,it is best to buy a 750w psu for future upgradings and present decent performance and of course latest 750w psu's are energy efficient than Iball psu's, if i say in twitter buy Antec high current psu. here is link for reference
