No... The power supply is simply a battery in the back of the laptop. But if you use a Desktop it is like any other power source.
The ocz 1kw pro xstream is considered the most efficient pwer supply.

No. The 240V lamp will pop the circuit or fuse because the draw is higher than the supply.
In the USA (110 voly supply) you should fit a 5 amp fuse. In Britain or Europe (230 volt supply) you should fit a 3 amp fuse.

The answer is 1
main circuit started with electricity supply flowing through the service fuse
Very unlikely. When a power supply "blows", a fuse is destroyed in the power supply. This is what the fuse was designed for. When a high voltage comes through, the fuse will burn out to prevent the surge from reaching the rest of the electronics. A surge protector does the same thing, but is better at catching voltage spikes than the power supply.
49 factors.
The fuse is rated to protect the equipment, the supply, and you. Change the fuse for a higher rating and you compromise your safety and equipment and supply safety; increasing the risk of electric shock and of fire.
If you mean the fuse in the plug that connects to the mains... no more than a 5 amp fuse.
To calculate the fuse rating for a 600 watt appliance on a 220 volt supply, you can use the formula: Fuse rating = (Power/Voltage). In this case, it would be 600 watts / 220 volts, which equals approximately 2.73 amps. Therefore, you would need a 3 amp fuse for the 600 watt appliance on a 220 volt supply.
