I heard of psu many times in this forum but didnt understand actually. Does it relate to power supply? If i buy a graphic card for my system do i need a separate power supply? I have no idea about the specifications of my smps , currently a 7200GS is working in it.i want to buy a 9500GT or above . do i need a psu or will it work with my old smps?
