I want to buy an Nvidia Geforce GTX 480 but I'm not sure if my psu will be able to handle it. I'm not sure what psu I have. My system specs are listed below: Intel Core 2 Quad Q8300 2.5GHz 6GB DDR2 RAM/MEMORY Nvidia Geforce GT 320 1TB HDD.
Im wondering if you can workout my psu or something with those specs that came with this computer.

If you don't have its package,then open the case and check the model(you may need to take it out)
A GT320 would suggest an OEM prebuilt PC, so I suspect it has a low wattage 300 - 350w PSU but let's see what the OP comes back with.
