What is the voltage for the poweredge 1500SC power Supply. I am trying to install a new Video card and it requires a 350volt power supply. Right now when I start the computer with the video card it is starting but I get no Video.  I am installing a Nvidia fx5200 with 256ram PCI. Please help I do online BF Vietnam gaming and need this new card to work. I have upgraded the Bios to A06
