Question:DOES THIS HIGHER WATTAGE UPGRADE MEAN A HIGHER ELECTRIC BILL? Would it hurt my PC which may or may not need that much power ?
Answer: This power supply delivers power On-Demand. That means it only delivers the power that's needed by the system, nothing more. If your PC now needs 500-Watt power because you added more components to your PC, it will use only 500-Watt. If your PC currently uses and needs only a 250-Watt power supply, it will use only 250-watt and operate leisurely.
