450W 80-Plus Bronze PSU
DO NOT cheap out on the Power Supply Unit. Its not as simple as adding up the wattage of the components and buying the closest rated of the available ones. A cheap PSU may output the wattage required but it may not stay there without fluctuations, which can damage components. A typical reliable PSU is categorized by its efficiency ratings (80 plus bronze/silver/gold). What it means is for every 100W drawn from the grid, atleast 80W will be supplied to the internal components and the rest is dissipated as heat. In my experience, the wattage is widely dependent on your GPU. My budget restricted me to get a non-modular one. 😐
