I'm gonna install an ATI Radeon HD 4650 into my computer so i can play fallout 3 and l4d without having the dreaded lag. However, I'm scared that this graphics card I'm going to install will take up to much power from the stock 170 W power supply in the computer already causing it to burn out. I can't find any power supplies that will fit into the case and have the required wattage. Is there any sites or types of power supplies that you all can recommend?
