Building a new PC - will this work?

[thejeremy]

Are you saying that my 430W PSU won't be enough? I'm not going to have multiple hard drives or anything, just one SATA drive, a DVD-ROM drive, one floppy drive, a video card, that's mainly it. No RAID setups or anything. I was looking at some of the component specs to see what the wattage was for them and I think I'll be ok but there were some that didn't show how much wattage it took. I don't wanna buy another PSU if this one is going to work. Are there any good websites that give approximate wattage ratings for all computer components so I can be sure?
