It's not really a major question but: Can I get a PSU that has a higher wattage than is necessary? What I mean is: Let's say I have a PC that only needs 450 watts of power. But I buy a 650 watt PSU because I plan to upgrade the GPU in the future. Would the 650 watt PSU damage the PC? Or would everything work as though it was running on a 500 watt PSU? Thanks for your help.
