You need a special tool to measure the power consumption of a computer, called a clamp meter. Most only have the ability to measure AC power consumption, so it tells you how much it draws from the wall, not how much is drawn from the power supply. But with the AC power consumption combined with the efficiency ratio of a PSU, you can quite easily calculate how much of a load is on the actual PSU. It's my best estimate that computer draws 150W at peak, based on a 70% efficiency PSU. __________________ __________________
