Hello everyone! I am new to TechSpot, I was a lurker before, and have gotten some great advice, at looking at other threads. But right not I have some problems. Ok I have a Dell Dimension 4700. It has 1GB RAM, Intel P4 2.8GHZ, ATI X300, and a 305WAT powersupply. A few days ago I ordered a MSI Nvidia 8500GT Video Card from Newegg, all the other brands for this card such as XFX, EVGA, BIOSTAR, said this card requires 300WAT, when I got my card it said on the manual 350WAT+ required. Anyways I also went to Extreme Power Supply Calculator, and put in everything I have along with the 8500GT, it said I need 276WAT, I have 305WAT would I be fine? Also does Dell Underrate there powersupplies. Also what kind of power supply do I have? Like ATX, ATX12V, cuz I cant find out, http://support.dell.com/support/edocs/systems/dim4700/sm/techov.htm#wp1053452. Thats the power supply I have, if anyone can help me that will be great!
