I currently have a Dell XPS 410 with a few upgrades(Intel Q6600 CPU, OCZ Vertex 2, 4GB RAM) and am going to upgrade the video card to a Galaxy GTX 460 and need a new power supply to do so. I don't really know much about power supplies which is why I am asking what will fit into my computer/work well with new video card. Probably looking to get a 600w or so. Thanks to anyone who can help.
