Help choosing power supply Gateway

[jdissonance]

Hello, I have a Gateway GT5464 and need to upgrade my power supply to use GEForce 8500GT video card. I currently run Delta Electronics 12V output. What are my options?

I thought this card will run even with a 250W PSU. However, if you want to upgrade your PSU, here is a new 400W PSU that even comes with a PCIe power connector.

It says it should work for your PC.
