Say your on the edge that PSU will eventually burn out (Peak power and a Normal Power) This is why I typically recommend people get a 500 Watt on the lowest end. Even though HP/DELL etc. tend to ship their systems with a 250–450 WATT PSU (depending) they leave no overhead for Video Card Upgrades.
How much power does my PSU draw?
Yes, a power supply draws power relative to how much is being used. So if your PC hardware is only using 200W, your 500W power supply won’t draw 500W. How much it draws will vary from power supply to power supply. A power supply is just a transformer or a transducer.
