i was thinking of picking up a Dell Dimension on the cheap. Its an AMD X2 system with integrated graphics. I wanted to upgrade the graphics but the system only has a 305W PSU. Does anyone know if I would have any problems with throwing in something like a 7600GT or X800GTO? If so what cards would be recommended for such a weak PSU. Thanks in advance.
The first thing you need to do is look at the specifications of the motherboard. Make sure it has a PCI-e x16 slot because many of the cheaper brandname PC with integrated graphics do not have dedicated GPU ports.
If the PC does have a PCI-e x16 slot then the 7600GT should work. At stock speed (either 400MHz or 450MHz Core), it consumes only 35.8w. There are many brands though that sells overclocked versions of thr 7600GT and naturally consume a little more power.
