Can you use a 12v 1200 ma power supply on a 12v 3 amp monitor?

NO. At the very least... NOT FOR LONG. (1200ma = 1.2 amps). Your 3 amp monitor draws nearly 3 times the current that your supply can safely pass thru its circuitry. It will either fail due to burnt component(s) on its circuit board, or its internal protection circuit will trip, preventing said damage. SO... either way... NO.

No, you should not use a 12V 1200mA (1.2A) power supply on a 12V 3A monitor. The power supply needs to provide at least the same amount of current (or more) than the device it is powering. In this case, the 1.2A power supply would not be able to provide enough current for the 3A monitor, and it could potentially damage the power supply or not provide enough power for the monitor to function properly.

Can a 12V 3.5A lcd monitor be replaced with a 12V 4.5A power supply?
Yes. However you will not be able to see anything as the 12V 4.5A power supply does not come with a screen.
What is a 12 volt rail on a power supply?
The + or - 12V output connection.
Can you use a 12v dc 1a power supply on device that requires 12v dc 3200ma?
No, 3200 ma = 3.2 amps
Say the power consumption of my 12v devise is 80 mA or less and the instructions say use a 12v 300 mA power supply and I use a 12v 800mA OK or not?
Generally, yes. If your devise will only draw 80mA, it will do it whether it is connected to a supply that is capable of supplying 300mA or 800mA. The amperage rating on the power supply is the highest current that it is rated for. It will easily and safely provide less current. The load that is connected to the power supply will determine the actual amount of current.
How does 12v dc 1.5 amp power adapter differ from 12v dc 3 amp power adapter?
12v 1.5amp power adapter is 18 Watt, can't load more than 18W power consumption,3amp power adapter can load 36W.
Can a 12V 3.5A lcd monitor be replaced with a 12V 4.5A power supply?
Yes. However you will not be able to see anything as the 12V 4.5A power supply does not come with a screen.
How you convert a power supply into 12v DC?
DC 12V power supply can convert 110/220V AC power source to 12V DC.
What are the 5 voltages produced by and ATX power supply?
+12V, -12V, +5V, -5V, +3.3V
What are five voltages that can be produced by an ATX or BTX power supply?
+3.3v +5v -5v +12v -12v
Why does a computer use 12V?
The input power of a computer Power Supply is usually 110-240VAC. The power supply usually transforms the input voltage into 3.3V, 5V, and 12V...all in DC. Different components require different voltage...either (1)ONE of a combination of these. 12V is one output voltage of the PSU(Power Supply)
How much does an average 12v Power Supply cost?
The average price of a 12v power supply depends on the item for with the power supply is needed. Universal AC/DC adapters can be as little as a few dollars, to branded items with is dependent on the manufacturers pricing structure.
What three voltage levels are commonly found on an ATX Power supply?
+12V, -12V, +5V, -5V, +3.3V
What is a 12 volt rail on a power supply?
The + or - 12V output connection.
Can you use a 12v dc 1a power supply on device that requires 12v dc 3200ma?
No, 3200 ma = 3.2 amps
What does a dual voltage power supply do?
It convert 220v or 115 to -12v and +12v by using many components and step down transformer.
What will happen if i connect a power supply of higher current rating to lower current load?
The supply won't have to work as hard. It is perfectly acceptable, for example, to use a 1A, 12v supply to supply a 12v, .5A load. The current rating indicates the ability of the supply to dissipate heat caused by the current flowing. If the load current is above the power supply current rating, the power supply will overheat.
How the power supply works in the computer?
The power supply in a computer runs the 110 volts mains power through a transformer into a lower voltage, then lowers that into different voltages (+5v, -12v, +12v, +3.3v) which i believe are then stabilised independently. The power supply also handles the turning on/off the voltages triggered by a signal from the motherboard.
