Can I substitute a 12V DC 700 ma power supply or wall wart with for a 12V DC 500 ma rated supply?

Yes you can but for devices use 12 v and 500 ma( 0.5 a)
<<>>
No, the output of the 500 mA power supply will be too small for a device that requires 700 mA to operate. It can be done the other way around though, a 700 mA power supply will operate a device that only requires 500 mA with 200 mA to spare.

What supplies power to a computer?
The "power supply" supplies power to a computer. A computer's power supply is a "switchmode power supply" responsible for converting the AC voltage from the wall into several DC output voltages.
What is the function of the power supply cable?
· A power cord, line cord or mains cable is known as the supply cable, which temporarily connects an appliance to the mains electricity supply to a wall socket. · A supply cable connects the refrigerator to the mains electricity supply via a wall socket.

Is power supply and inventory are same?
No, an inventory is what is in stock; a power supply powers an electronic device and determines wattage and voltage, usually from a wall outlet.
What is the difference between an external USB 2.0 hard disk that needs a power supply and one that does not require a power supply?
A USB hard disks that does not require a power supply is powered by your computer via the USB connection. Where as others require an external power supply because of the amount of power they require. It is usually a "wall wart" type that plugs in to your wall socket with a lead that plugs in to the disk drive.
What is the function of power supply in system unit?
The function of the power supply is to convert wall current to the correct current for the computer and distribute power to all the internal computer components.
What regulates the wall voltage to the voltages required by the computer chips?
The Power Supply
Can you plug a tattoo power supply directly into a domestic wall socket?
yes
What voltage does the power supply uses in US?
Input would be 120v at 60hz. Standard US wall power.
Which device converts 120volt ac from what if your wall to 12vdc for your computer to use?

Can the power supply cause the computer to be difficult to turn on?
Yes. If the power supply is of a low wattage and has too many pieces of hardware connected to it, it can. Try buying a power supply with a wattage over 300. One thing to check before replacing the power supply is the voltage selector in the back. If you use 120 volt power, then setting the power supply to 240 volts will cause the PC to only get half of the power it needs. External peripherals with their own power supply will not impact the power supply or current in the computer. Printers and monitors usually get their power from the wall socket, not the computer, and the same goes for external modems that plug into the wall. Keyboards and mice take negligible power.
