I was thinking of upgrading the power supply that came with my case to something more stronger so I wouldn't have to worry about it in the future. The two I'm thinking about getting are OCZ ModStream or Antec TRUEPOWERII. My computer is ASrock 939 dual sataii,AMD64 3200 ocd to 2.34, 6600gt agp ocd ( I want to upgrade it soon),1gb 2x512mb ram, a dvd drive,cd drive, 2 hardrives, floppy drive and some case fans.
