 That's a highly variable parameter. You can use a kill-a-watt meter to find out the power consumption of the whole system or you can just guess using the watts posted on the devices. A typical household outlet can provide anywhere between 1800w to 2400w depending on the fuse fitted with it (15A or 20A).
