Hi dv29..... & welcome
according to
THIS i see no reason it wont work, but you already know your generic PSU probably wont cut it, does the existing PSU have a dedicated 6pin plug for PCI-e..??
a 9600 is hardly a power hungry card, depending on the amount of peripherals you have
THIS will run the 9600 all day long & its a solid power unit.
just use a DVI to VGA dongle found
