I have a Gateway GT5082 desktop of my wifes and I have a extra 8800 GTS laying around and was goin to put it in her desktop. Now my first question is it has a 300 watt power supply in it and I dont think it will be big enough to hold it but someone else told me it would. The pc just has a dual core amd processor, has bout 1.5 of ram running at 400 mhz. and one optical and one HDD. Now I dont think the 300 will hold it but I was just wanting to verify. Now my 2nd question is if it cant will any aftermarket power supply fit in there or will I have to find one that will go. Because actually I think I will have to find another power supply cause I dont think the one in it has a pci-express connector. Thanks guys.
