Hi. I currently have the Radeon 9550 and am not pleased with the performance I am getting in games. I am planning on getting something a little faster, but still affordable. I have found two cards, either the Radeon HD 2400 Pro or 2600 Pro both AGP. I will probably try to get the 2600. I will need a new power supply. I have found a 500 W Power Supply ATX and I would like to know if it is powerful enough to run the card. Currently I have a generic 300 Watt PSU which I assume probably wont run it correctly.

Check this link for specific power supply and tell me if it will be able to run on my pc and will it be enough to power the card.
