I'm Looking to upgrade a PSU for a Dell Dimension 2400, either 300-450w range. I'm not very tech savvy to say the least, so I'm not sure if it's even possible to upgrade on a 2400. If it is possible to upgrade I'm not concerned price wise, more concerned if it would fit my case, and compatibility. Any suggestions on a good PSU? Thanks in advance. 7ce - Current PSU is 200w, upgrading for a new vid card which requires a min of 300w. - Searched Forums, no luck on finding similar threads. If so hopefully someone can point me in the right direction.
