Hello i have a 2002 year computer when i bought it it does have a brown slot which is a agp slot and i was wondering do i need to upgrade my power supply if i get Radeon Sapphire 9600XT 128MB 500-600MHz AGP?
you prolly have a 300-350 watt psu so you should be OK. You can check what wattage it is by opening your side panel and looking on teh side it should say "DC Output: 300W" or something like that.
