I just purchased a Dell Inspirion 580 with an i5-750 processor and want to upgrade the Power Supply Unit from the standard 300 watt to something that can sustain a higher end graphics card. Since this is a new computer, I do not want to damage it so I inquired with a Dell rep before messing around with it. They told me upgrading the PSU would fry the motherboard. This made my BS meter rise a bit and so wanted to see if I can put teeth to it or not.
Has anyone upgraded this model? If so, any issues?
Are there any special considerations regarding connector types, or are they standard? In past experiences upgrading machines, would you assume that since the form factor and wattage are appropriate that the pinouts would be standard, or should they be verified before installation?
