Which would you use for a 250W appliance and why?
I would use a 300W power supply for a 250W appliance. It's recommended to have a power supply that can handle more than the actual wattage of the appliance to ensure efficient operation and prevent overloading. In this case, a 300W power supply would provide enough headroom to safely power the 250W appliance.

Can you use 5 volts 1.2 amp power supply on 5 volts 3.0 amp device?
No you can not. The power supply output of 1.2 amps is under sized. You would need to have a power supply of 3 amps or larger.
Is there any difference in the consumption of electricity by using two sizes of power supply for example a 350watt power supply and a 480watt power supply with all else being the same on the comp?
The computer will only consume what power it needs. No diffference. if you have a 350watt power supply, and it is using more then 70% power consuption, the life of that power supply will be short, so always aim big when picking out a power supply, ie: 50-100 watts more than what you would actually need.
