Hi guys, thanks for your time, i'm putting together a new rig and was just wondering whether or not i should get a new power supply thta has the pci express power cable, or save the money and buy the pci e cable adapter for the 420watt power supply that came with my case. I am not sure if the power is enough for c2d 6400, corsair 1gig (512x2) ddr2 800, 250gig sata2 hdd, 7900gt 256mb, and a samsung dvd burner. thanks again
