The Silencer 500 Dell PPCS500D replacement/upgrade Power Supply is higher wattage than my old power supply. Will this hurt my Dell computer?
The higher wattage will not have any negative effect for your Dell computer. It simply allows you to add additional drives and upgrade your video card, which the original Dell power supply would not be able to handle.
