the case name is: Thermaltake V3 Black Edition Mid Tower Case - ATX, Micro ATX, 120mm LED Fan, 4x 5.25 Bays, 5x 3.5 Bays
and the PSU i believe is 500W
The make and model would be helpful. A low quality 500w PSU may not power the card while a high quality unit wouldn't have a problem. A low quality unit may even damage other components when put under a load, you could be playing BF4, hear a pop, release the magic smoke and fry the whole system.
