"What power supply do I need ? To answer this question we came up with a tool that determines the overall computer power supply wattage as well as amperage required for +12V, +5V and +3.3V rails for your desktop computer, server, or any pc computer system that uses ATX power supply." - eXtreme Outer Vision
"The Wattages listed are maximum peak wattage for each component. The total amount this calculator figures is for all devices running at peak utilization. It is important to bear in mind that this amount will never be reached under typical operation. However, I feel that this tool will give you a better idea of how much power your system will need.
After all - when it comes to power, having excess wattage on a power supply is never a bad thing!" - Journey Systems
"The PSU Wattage we recommend only gives you a general idea on what to consider while selecting a power supply." - Newegg.com
