[QUOTE="Taipan, post: 33339, member: 11681"] No, that's just the maximum rated DC power that it can deliver. Typically, PC switch-mode power supplies are better than 75% efficient, so if you are drawing 200W from it, the power supply will be wasting another 25% (50W) as heat and will be drawing a total of 250W from your AC mains. This is true irrespective of the maximum output rating of the power supply - whether it is a 200W or a 500W.... :) [/QUOTE]
