And they're trying to help you get that information. Say you had a computer with an OC'd Q6600, 8GB OC'd RAM, 4 DVD drives, and 2 floppy drives. It would take about a 700W PSU to power all of this, and 700W is well above what is recommended for a 9600GT. However, because of all of the devices drawing on the PSU, the video card would not get enough power because it draws 180W and some (don't know how many) amps from the PSU rail. This is why Mr. Big and Reinier
asked you what else (like cd drives) you had hooked up into your computer. Your PSU brand and model would be VERY useful info, too.
